Description

The invention relates, in particular with several aspects of the invention, to a chainsaw, especially a motor chainsaw. It is an object of the present invention to create a chainsaw that has special, in particular improved, properties. In particular, it is intended to enable improved shielding of an area of ​​the chainsaw housing against mechanical environmental influences. This problem is solved by the subject matter of the independent patent claim. Preferred embodiments are the subject matter of the dependent patent claims. The wording of all patent claims is incorporated by express reference into the present description. The invention aspects mentioned above and / or below can be implemented individually or jointly. A chainsaw according to one of the invention aspects can, if necessary, also be further developed according to another invention aspect. In particular, the invention aspects can be implemented in the same chainsaw. Embodiments of the invention – unless expressly specified in a complete manner or otherwise mutually exclusive – can in principle be based on any of the invention's aspects individually or on a combination of some or all of them. The same applies in particular to expedient specifications. A chainsaw according to a first aspect of the invention comprises a housing. The housing has a lower longitudinal edge region that connects a bottom surface of the housing with a side flank surface of the housing. In particular, the longitudinal edge region extends substantially along a longitudinal direction of the chainsaw. The chainsaw also has a side plate section, which is designed to partially shield the housing, particularly mechanically. The side plate section can partially cover the housing in order to shield a covered area of ​​the housing. The side plate section covers at least a portion of the lower longitudinal edge region of the housing.In this case, at least the section of the lower longitudinal edge is covered by the side panel in such a way that a base area of ​​the side panel, extending at an angle to the lateral flank surface, essentially runs in lateral extension of the underside base surface of the housing. The base area of ​​the side panel may be angled relative to the contact surface. The base area of ​​the side panel may be folded over onto the longitudinal edge area towards the base surface. The base area of ​​the side panel may geometrically complete the base surface of the housing and / or functionally reinforce the edges. In this way, the lower longitudinal edge area of ​​the housing can be at least partially shielded from external mechanical impact by means of the side panel. This can be particularly advantageous if the housing in the lower longitudinal edge area has a housing material that is relatively soft compared to the side panel, or if it is made of such a material. The housing material of the chainsaw can be made of a polymer material, if appropriate. The phrase "essentially extending laterally" can be appropriately understood as "essentially running in a common plane to one side" and / or as "essentially flush," in particular "flush with the surface." "Essentially" may include an offset, which may or may not be present, for example, a surface offset of up to 0.2 mm and / or an angular offset of up to 5°. In an embodiment of the invention, particularly starting from the first aspect of the invention, the side panel part has a contact surface for attaching a saw chain guide bar for the chainsaw. The contact surface extends substantially parallel to the lateral flank surface of the housing. In a further embodiment of the invention, particularly starting from the first aspect of the invention, the chainsaw has a mounting device. The mounting device defines a mounting plane, in particular for the chainsaw. The mounting device is designed to contact a surface for the chainsaw within the mounting plane, especially when the chainsaw is mounted or placed on the surface. A gap is present between the mounting plane and the bottom area of ​​the side panel. This gap can be a minimum of 1 mm and / or a maximum of 10 mm, in particular between 3 mm and 7 mm, and more, in particular, approximately 5 mm. The gap can be measured perpendicular to the mounting plane. The mounting device may expediently have at least one base, for example two or more bases, and / or at least one support rib. At least one base and / or at least one support rib may project from the underside of the housing, in particular integrally. In a further embodiment of the invention, particularly starting from the first aspect of the invention, the side panel part has a collar section extending around its outer circumference. Specifically, the collar section extends around the outer circumference of the side panel part and / or projects at an angle, particularly perpendicular, to the housing relative to the contact surface. The collar section forms the base region of the side panel part. In other words, the base region of the side panel part can be a portion of the collar section. The circumferential collar section can mechanically stiffen the side panel part. The collar section can border and / or frame a lateral flank section of the housing. In a further embodiment of the invention, particularly starting from the first aspect of the invention, the side panel has a transition area that extends longitudinally parallel to the lower longitudinal edge area of ​​the side panel. The side panel also has a contact area that comprises or forms the contact surface. The transition area of ​​the side panel connects the contact area of ​​the side panel with the lower bottom area of ​​the side panel. The transition area is rounded, particularly at least on its outer side, and especially opposite the housing. Specifically, the transition area has at least one edge rounding with an outer radius of 1 mm to 10 mm. Such a transition area can counteract the chainsaw from tilting against the tree trunk when pruning a tree trunk with a chainsaw. In a further embodiment of the invention, particularly starting from the first aspect of the invention, the transition area of ​​the side panel section has a substantially planar inclined surface area. This inclined surface area is designed to slide, particularly tangentially, along a tree trunk to be pruned. In a further embodiment of the invention, particularly starting from the first aspect of the invention, an air gap is present between the side panel part and the housing in certain sections, measuring approximately 0.6 mm, and in particular approximately 0.1 mm, perpendicular to the contact surface. In particular, the air gap is present only in certain sections, so that the side panel part and the housing can contact each other without gaps in other areas. In a further embodiment of the invention, particularly starting from the first aspect of the invention, the side panel part is made of a sheet metal part with a thickness of 0.2 mm to 0.5 mm, in particular 0.3 mm. Alternatively or additionally, the side panel part has such a thickness at least in certain areas. In particular, the sheet metal part is a steel sheet or an aluminum sheet. The side panel can be designed monolithically for practical purposes. In a further embodiment of the invention, particularly starting from the first aspect of the invention, the lower longitudinal edge region of the housing has a groove. The groove can extend longitudinally along the longitudinal direction of the chainsaw. The groove of the lower longitudinal edge region is designed to receive the underside bottom region of the side panel. In particular, the underside bottom region of the side panel is at least partially received by the groove. The groove can be advantageously designed to accommodate the bottom section of the side panel in a manner that is essentially flush with the contact surface. If necessary, the bottom section of the side panel can be accommodated by the groove in a manner that is essentially flush with the contact surface. In a further embodiment of the invention, particularly starting from the first aspect of the invention, the chainsaw has a machine width measured perpendicular to the contact surface of the side plate. Specifically, the machine width is measured without the chainsaw handle, i.e., with the handle removed. It can therefore be a handle-free machine width. The side plate has an extent measured parallel to the machine width. The extent of the side plate, measured parallel to the machine width, is less than 50% of the machine width. Specifically, the underside bottom area of ​​the side plate extends along the machine width and terminates towards a longitudinal median plane of the chainsaw that bisects the machine width. In other words, the bottom area can project along the machine width towards the longitudinal median plane and / or terminate at a distance from the longitudinal median plane. In a further embodiment of the invention, particularly starting from the first aspect of the invention, the chainsaw has a catch hook section that points away from the housing. The catch hook section is detachably attached to the housing by means of a detachable fastening of the side plate part. In particular, the catch hook section is detachably attached to the housing of the chainsaw by means of a screw connection such that the side plate part is clamped between the catch hook section and the housing. The catch hook section serves in particular to catch a saw chain that jumps off the guide bar, especially by hooking it. In particular, the side plate can have an opening in the area of ​​the catch hook section through which components behind it can protrude to provide force support. Alternatively or additionally, it may be conceivable to provide the side plate section with another opening for other components, especially for sealing these components to each other without involving the side plate itself. In a further embodiment of the invention, particularly starting from the first aspect of the invention, the housing carries a drive motor, especially an electric one, for the chainsaw. The drive motor is designed to provide drive power for a saw chain guided circumferentially on the guide bar. The side panel has a through-hole for passing a drive shaft of the drive motor through it. The drive shaft can carry and / or drive a drive pinion for the saw chain. In a further embodiment of the invention, particularly starting from the first aspect of the invention, both the housing and the side panel each have positioning aids for assembly. The positioning aids of the housing and the positioning aids of the side panel are complementary to each other. In particular, the positioning aids of the housing are formed by laterally projecting bolts, and the positioning aids of the side panel are formed by bores, each for receiving one of the bolts. Two such bolts and two such bores can be provided. The housing's positioning aids can also be used to attach the saw chain guide bar, which is equipped with corresponding holes. The bolts are threaded bolts. Nuts can be screwed onto these threaded bolts to clamp the saw chain guide bar between the mounting surface and a sprocket cover of the chainsaw. In a further embodiment of the invention, particularly starting from the first aspect of the invention, the saw chain guide bar can be mounted between the sprocket cover of the chainsaw and the contact surface of the side plate. The sprocket cover is arranged at a distance from the mounting surface, with this distance between the sprocket cover and the mounting surface being 25 mm to 35 mm. In particular, the distance is measured perpendicularly from the mounting surface to the point of the sprocket cover closest to the mounting surface, in particular the lowest point, when the chainsaw is mounted on the ground. A chainsaw according to a second aspect of the invention has a housing and a brake lever that is pivotably mounted relative to the housing. In particular, the brake lever can be pivoted for actuation. Specifically, by actuating the brake lever, a saw chain guided circumferentially on a guide bar for the chainsaw can be braked, in particular stopped. The chainsaw has a side plate section designed to partially shield the housing. This side plate section has a contact surface for the guide bar of the chainsaw. The brake lever has a shielding contour. The side plate section has a shielding section. The shielding section of the side plate section and the shielding contour of the brake lever are complementary to each other.The shielding contour of the brake lever and the shielding section of the side panel part work together to shield the housing, especially in the area of ​​a bearing device for mounting the brake lever relative to the housing. The interaction of the shielding section and the shielding contour prevents the ingress of foreign matter, particularly in the form of chips, into the bearing assembly for the brake lever. In particular, the interaction of the shielding section and the shielding contour allows the bearing assembly to be sealed, at least partially, against the external environment of the chainsaw, and especially to be at least or exclusively chip-tight. The brake lever can be referred to synonymously as the chain brake lever. The chainsaw expediently has a setup device, wherein the setup device defines a setup plane and is designed to touch a surface in the setup plane. Advantageously, the housing has an upper longitudinal edge area extending along a longitudinal direction of the chainsaw, which connects an upper top surface of the housing opposite the mounting device with a, in particular, a lateral flank surface of the housing. The brake lever should point away from the setup device. Advantageously, the brake lever is mounted by means of the bearing device so that it can pivot about the pivot axis relative to the top surface, the pivot axis being parallel to the installation plane and perpendicular to the longitudinal direction of the chainsaw. The contact surface of the side panel part is expediently extended in a manner that is essentially parallel to the lateral flank surface of the housing. In an embodiment of the invention, particularly starting from at least the second aspect of the invention, the shielding section of the side panel part projects beyond an edge region of the side panel part, in particular in a tongue-like manner. Alternatively or additionally, the shielding section of the side panel part can project beyond the upper longitudinal edge region of the housing, in particular in a tongue-like manner. In particular, the shielding section projects beyond the collar section of the side panel part, in particular in a tongue-like manner and / or substantially parallel to the contact surface. In a further embodiment of the invention, particularly starting from the second aspect of the invention, the shielding contour of the brake lever extends segmentally along an imaginary circle concentric with the pivot axis of the brake lever. In this way, the shielding interaction of the shielding section and the shielding contour can be maintained over the entire pivoting range of the brake lever relative to the housing. In a further embodiment of the invention, particularly starting from the second aspect of the invention, the pivot axis of the brake lever runs between the top surface of the housing and the mounting device of the chainsaw. In a further embodiment of the invention, the shielding section of the side plate part is slidably attached to the shielding contour of the brake lever. In particular, the shielding section is slidably attached to the shielding contour axially with respect to the pivot axis of the brake lever and / or not radially with respect to the pivot axis of the brake lever. In particular, the shielding section and the shielding contour can be in surface contact with each other. In a further embodiment of the invention, particularly starting from the second aspect of the invention, the shielding contour of the brake lever has a recessed receiving groove. The receiving groove can be axially recessed with respect to the pivot axis of the brake lever. The receiving groove receives at least part of the shielding section of the side plate part. Thus, at least a part of the shielding section can project into the receiving groove, particularly axially with respect to the pivot axis of the brake lever. In particular, the shielding contour and the shielding section can interact in the manner of a labyrinth seal. Advantageously, the shielding section of the side panel has a flange section projecting radially outwards with respect to the pivot axis of the brake lever, the flange section being abutted against the shielding contour of the brake lever. In particular, the flange section is abutted against a groove bottom surface of the receiving groove of the shielding contour. In a further embodiment of the invention, particularly starting from the second aspect of the invention, the shielding contour of the brake lever has a contour collar section, wherein the contour collar section projects axially with respect to the pivot axis of the brake lever. In particular, the contour collar section has a radially outer groove flank of the receiving groove of the shielding contour. In particular, the shielding section of the side plate part does not contact the outer groove flank. The side plate part has at least one edge-interrupting recess through which the contour collar section extends, in particular along the circle concentric with the pivot axis of the brake lever. In particular, the side plate part has two such edge-interrupting recesses that flank the shielding section of the side plate part and through which the contour collar section extends. In a further embodiment of the invention, particularly starting from the second aspect of the invention, at least one lever section of the brake lever, which integrally incorporates the shielding contour, comprises or consists of a polymer material. It is conceivable that the entire brake lever is formed with or from a polymer material. In a further embodiment of the invention, particularly starting from the second aspect of the invention, the side panel part is made from a sheet metal part with a thickness of 0.2 mm to 0.5 mm, in particular 0.3 mm. Alternatively or additionally, the side panel part can have such a thickness, at least in certain areas. The sheet metal part can be made of steel or aluminum.

A hand-held processing device 100 in the form of a chainsaw 1 has a housing 4. The housing 4 has a lower longitudinal edge region 5. The lower longitudinal edge region 5 extends, for example, along a longitudinal extension direction 11 of the chainsaw 1. The housing 4, for example, has a bottom surface 5A and a side flank surface 6. The bottom surface 5A and the side flank surface 6 are connected to each other by means of the lower longitudinal edge region 5 of the housing 4. The lower longitudinal edge region 5 can form a transition between the side flank surface 6 and the bottom surface 5A. The side flank surface 6 can run essentially perpendicular to the bottom surface 5A. In handheld operation of the chainsaw 1, the side flank surface 6 is specifically oriented away from the user operating the chainsaw 1. The housing 4, for example, has an upper longitudinal edge region 12 that extends along the longitudinal direction 11 of the chainsaw 1. The housing 4 also has a top surface 12A. The upper longitudinal edge region 12 connects the top surface 12A with the side flank surface 6. The housing 4 can be made of multiple parts. The chainsaw 1 has a side panel 7 for partially shielding the housing 4. For example, a front area of ​​the housing 4 in the longitudinal direction 11 can be shielded by means of the side panel 7. For example, the side panel 7 adjoins the housing 4 in a lateral direction 81 of the chainsaw 1. The lateral direction 81 is perpendicular to the longitudinal direction 11. The flank surface 6 of the housing 4 is, for example, oriented essentially orthogonally to the lateral direction 81. The side panel part 7 is, for example, made from a sheet 27. The sheet 27 can have a thickness of at least 0.2 mm and / or at most 0.5 mm, for example 0.3 mm. Alternatively or additionally, the side panel part 7 has a thickness 28 of at least 0.2 mm and / or at most 0.5 mm, in particular 0.3 mm. The sheet 27 can be a steel sheet or an aluminum sheet. The side panel part 7 can be a formed part, for example a deep-drawn part. The side panel part 7 is, for example, monolithic. The side panel 7 has a contact surface 8 designed for the attachment of a saw chain guide bar 50 for the chainsaw 1. The saw chain guide bar 50 is designed for the circumferential guidance of a saw chain 51. The contact surface 8 of the side panel 7 extends substantially parallel to the lateral flank surface 6 of the housing 4. In particular, the contact surface 8 is oriented orthogonally to the lateral direction 81. The chainsaw 1, for example, has a brake lever 13, by actuating which the saw chain 51 can be slowed down, in particular stopped. The brake lever 13 is pivotally mounted relative to the housing 4. For example, the brake lever 13 has a shielding contour 16, which is particularly integral. The side plate part 7 has a shielding section 18 that is complementary to the shielding contour 16 of the brake lever 13. The shielding section 18 and the shielding contour 16 interact in such a way that they jointly shield the interior of the housing 4 in certain areas, particularly from chips lifted by the saw chain 51. For example, the chainsaw 1 has a bearing assembly 14 by means of which the brake lever 13 is pivotally mounted relative to the upper surface 12A about a pivot axis 15 that runs parallel to the lateral direction 81 and perpendicular to the longitudinal direction 11. In this case, the shielding contour 16 and the shielding section 18 interact in such a way that they shield the bearing assembly 14, in particular against the ingress of chips from the outside, and in particular seal it. Specifically, "seal" can be understood as "shielding that is not gas-tight and / or liquid-tight." The chainsaw 1, for example, has a mounting device 2. The mounting device 2 defines a mounting plane 3 and is designed to contact a surface 400 in the mounting plane 3 when the chainsaw 1 is mounted on the surface 400. The mounting plane 3 can run parallel to the width direction 81 and / or parallel to the length direction 11. The mounting plane 3 can run substantially parallel to the underside surface 5A of the housing 4. Alternatively or additionally, the underside surface 5A can face the mounting plane 3 and / or be exposed. The side panel part 7, for example, has a bottom area 10 that extends at an angle, in particular at right angles, to the lateral flank surface 6 and / or to the contact surface 8. For example, the side panel part 7 covers at least, in particular only, a section 9 of the lower longitudinal edge area 5 such that the bottom area 10 of the side panel part 7 extends substantially laterally in line with the lower bottom surface 5A of the housing 4. For example, the bottom area 10 of the side panel part 7 can extend the lower bottom surface 5A of the housing 4 substantially parallel to the lateral direction 81. For example, there is a gap 19 between the base area 10 of the side panel part 7 and the mounting level 3. The gap 19 can be at least 1 mm and / or at most 10 mm, for example approximately 5 mm. The gap 19 can correspond to a base height and / or a base rib height of the mounting device 2. With respect to the lateral direction 81, a gap may be present between the facing edges of the base surface 5A of the housing 4 and the base area 10 of the side panel 7, which extends longitudinally, in particular, along the longitudinal direction 11. Alternatively, the facing edges of the base surface 5A and the base area 10 may be joined together essentially without gaps. The side panel part 7 has, for example, a collar section 20 that extends, in particular substantially, around its outer circumference. "Substantially" can refer to the fact that, under certain circumstances, one or two edge-interrupting recesses 47 may be provided in the side panel part 7. The angled, in this case right-angled, projecting bottom area 10 of the side panel part 7 is, for example, a subsection of the collar section 20. The side panel part 7, for example, has a contact area 22 that includes or forms the contact surface 8. The side panel part 7 can also have a transition area 21 that extends longitudinally parallel to the lower longitudinal edge area 5 and connects the contact area 22 with the underside bottom area 10 of the side panel part 7. In this case, the transition area 21 is rounded on an outer surface of the side panel part 7 facing away from the housing 4. An edge rounding 23 of the transition area 21 can, for example, have an outer radius 24 of at least 1 mm and / or at most 10 mm. The transition area 21 has a substantially planar inclined surface area 25. The inclined surface area 25 extends, for example, parallel to the longitudinal direction 11 and is set at an acute angle relative to the mounting plane 3. The inclined surface area 25 is designed to slide along the outer circumference of a tree trunk being delimbed by means of the chainsaw 1. For example, an air gap 26 exists between the side panel part 7 and the housing 4, in this case only in sections. The air gap 26 can have a maximum extent of approximately 0.2 mm perpendicular to the contact surface 8. The lower longitudinal edge region 5 of the housing 4, for example, has a groove 29. The groove 29 extends longitudinally along the longitudinal direction 11 and is recessed perpendicular to the longitudinal direction 11. The groove 29 can be a longitudinal groove of the longitudinal edge region 5. In this case, the groove 29 serves to receive the lower bottom region 10 of the side panel part 7. It is conceivable that the bottom region 10 is received in the groove 29 essentially flush with the contact surface. The chainsaw 1, for example, has a sprocket cover 39. The saw chain guide bar 50 can be attached, in particular detachably, between the sprocket cover 39 and the mounting surface 8. A distance 40 can be present between the sprocket cover 39 and the mounting surface 3, which in this case is 25 mm to 35 mm. The shielding section 18 of the side panel part 7, mentioned above, projects, for example, beyond an edge region 7A of the side panel part 7. The collar section 20 can have the edge region 7A. In this case, the shielding section 18 projects tongue-like beyond the upper longitudinal edge region 12 of the housing 4. When the side panel part 7 is mounted, the edge region 7A and the upper longitudinal edge region 12 can run essentially parallel to each other. For example, the shielding contour 16 of the brake lever 13 extends segmentally along an imaginary circle 17, the circle 17 being concentric to the pivot axis 15 of the brake lever 13. The pivot axis 15 of the brake lever 13 runs between the top surface 12A of the housing 4 and the mounting device 2. Accordingly, the bearing device 14 can be located at least partially inside the housing 4. The shielding section 18, for example, rests against the shielding contour 16 in a sliding manner. There can be no radial contact between the shielding section 18 and the shielding contour 16 with respect to the pivot axis 15, whereas there is only axial contact between the shielding section 18 and the shielding contour 16. In particular, the shielding section 18 and the shielding contour 16 are axially aligned with each other over a flat surface. The shielding contour 16, for example, has a receiving groove 41. The receiving groove 41 can be axially recessed with respect to the pivot axis 15. The receiving groove 41 receives at least part of the shielding section 18. The shielding section 18 can have a flange section 43 projecting radially outwards with respect to the pivot axis 15. The flange section 43 can be positioned against the shielding contour 16. For example, the flange section 43 is laid flat against a groove bottom surface 44 of the receiving groove 41 of the shielding contour 16. The shielding contour 16, for example, has a contour collar section 46. The contour collar section 46 can project axially with respect to the pivot axis 15. For example, the contour collar section 46 has a radially outer groove flank 45 of the receiving groove 41. The groove flank 45 and the flange section 43 can be radially spaced apart from each other with respect to the pivot axis 15. As already mentioned, the side panel part 7 can have at least one edge-interrupting recess 47. In this case, the side panel part 7 has two such edge-interrupting recesses 47 that flank the shielding section 18. The contour collar section 46 extends through the edge-interrupting recesses 47 along the circular line 17 and / or is movable. The shielding contour 16 can be an integral part of a lever section 48 of the brake lever 13. At least this lever section 48 comprises a polymer material, in particular a plastic material. It is conceivable that at least the lever section 48 of the brake lever 13 consists of such a polymer material. For example, the chainsaw 1 has a handle-free machine width 30. The machine width 30 can be measured along the width direction 81. The side plate part 7 can have an extent 31 measured parallel to the width direction 81, which is, for example, less than 50% of the machine width 30. The chainsaw 1, for example, has a longitudinal median plane 31A orthogonal to the width direction 81. In this case, the longitudinal median plane 31A bisects the machine width 30. The underside bottom area 10 of the side plate part 7 extends, for example, in the width direction 81 towards the longitudinal median plane 31A, in particular without cutting into or touching the longitudinal median plane 31A. The chainsaw 1, for example, has a catch hook section 32 on which the saw chain 51, which may jump off the saw chain guide bar 50, can become entangled. The catch hook section 32 can be detachably attached to the housing 4, for example by means of a screw connection 33. The side plate part 7 can be fastened between the catch hook section 32 and the housing 4, in particular by means of the screw connection 33. The catch hook section 32 can thus fulfill a dual function: catching the falling saw chain 51 and fastening the side plate part 7, in particular by means of a washer. The housing 4, for example, carries a drive motor 34, in particular an electric one, for the chainsaw 1. The drive motor 34 is designed to provide drive power for the saw chain 51, which is guided circumferentially on the saw chain guide rail 50. The side plate part 7, for example, has a through-hole 35 through which a drive shaft 35A of the drive motor 34 passes. If the saw chain 51 jumps off the guide rail 50 towards the housing 4, the side plate part 7 can prevent the saw chain 51 from contacting the housing 4. In particular, the handle-free machine width 30 can be measured in the area of ​​the drive shaft 35A of the drive motor 34, especially on a rotation axis of the drive shaft 35A. For example, the drive power provided by the drive motor 34 can be based on electrical energy drawn from a battery pack 200. The chainsaw 1 can have a receiving device 49 designed for the interchangeable receiving of the battery pack 200 in a receiving direction 60. Simultaneously with receiving the battery pack 200, it can be electrically connected to the chainsaw 1. The received battery pack 200 can be removed from the receiving device 49 opposite the receiving direction 60. The receiving direction 60 can be at an angle, for example, perpendicular or – as in this case – acute, to the mounting plane 3 and / or parallel to the longitudinal center plane 31A. In this case, the receiving direction 60 is directed away from the saw chain guide bar 50, so that the battery pack 200 can be received from the front top to the rear bottom. The chainsaw 1 or...The processing device 100 trained by the chainsaw 1 can be battery-electrically operated. For example, housing 4 has positioning aids 36A. Side panel part 7 can have complementary positioning aids 36B. The positioning aids 36A and 36B of housing 4 and side panel part 7 can be coordinated for relative positioning of housing 4 and side panel part 7 for assembly. The positioning aids 36A of the housing 4 can be formed by, in particular, two and / or in the longitudinal direction 11 spaced apart from each other, laterally projecting bolts 37, whereas the positioning aids 36B of the side plate part 7 are formed by bores 38 each for receiving one of the bolts 37. The positioning aids 36A of the housing 4 can, for example, also be used to attach the saw chain guide rail 50, which is provided with corresponding bores. The bolts 37 are, for example, threaded bolts. Nuts 370 can, for example, be screwed onto the threaded bolts to detachably clamp the saw chain guide rail 50 between the contact surface 8 and the sprocket cover 39. The nuts 370 can be placed against the sprocket cover 39. In its state when mounted on the chainsaw 1, the saw chain guide bar 50 can be extended essentially along the longitudinal extension direction 11 and / or parallel to the longitudinal center plane 31A. The illustrations in Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 to 11 can refer to the same embodiment of the chainsaw 1. In particular, the details shown can be those of a single processing device 100 in the form of the chainsaw 1. In an alternative embodiment, for which bracketed reference numerals are shown in Fig. 3, the aforementioned function of the side panel part 7 can be divided between two separate sheet metal parts 7B and 7C. A first sheet metal part 7B can be a contact plate part having the contact surface 8, while a second sheet metal part 7C functions as a housing lower edge cover. An edge of the side panel part 7 and / or an edge of the contact plate part 7B can run along a dividing line T. Under certain circumstances, one of the sheet metal parts 7B or 7C can be omitted, particularly if only one aspect of the invention is to be implemented. In the illustration of Fig. 12, the sheet metal part 7B is shown separately by way of example, which may be used alone as a side sheet metal part 7, in particular to realize only the first aspect of the invention by means of this sheet metal part 7B or side sheet metal part 7.
