[0032] Further advantages and features of the invention will become apparent from the claims and the following description of preferred embodiments of the invention, which are illustrated with reference to the drawings. Like reference numerals refer to like, similar, or functionally identical components.

[0033] It is understood that the features mentioned above and those to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention. Fig. 1 shows a schematic perspective view of an embodiment of a hand-held battery-operated electrical processing device according to the invention, Fig. 2 a detail of the electrical processing device in a schematic perspective view, wherein a battery pack, hidden for better clarity, is held by a holding device of the electrical processing device, Fig. 3 in the representation of the Fig. 2 corresponding representation an embodiment of a processing system according to the invention with the electrical processing device according to the Fig. 1 and Fig. 2, and Fig. 4 a further embodiment of the electrical processing device according to the invention in a roughly schematic plan view.

[0034] A hand-held, battery-operated electrical processing device 1 according to the invention has a receiving device 3. The receiving device 3 serves to replaceably receive an electrical battery pack B. The battery pack B can be exchangeably received in a receiving direction A of the receiving device 3. The receiving device 3 has a receiving recess 4 that extends along the receiving direction A and is essentially designed to complement the battery pack. In addition, the electrical processing device 1 has an output device 5. The output device 5 is configured to automatically output a message M to a user of the electrical processing device 1 if no battery pack B is received by the receiving device 3.

[0035] The electrical processing device 1 is comprised by a processing system 100 according to the invention. The processing system 100 has an electrical battery pack B for storing electrical energy. The battery pack B of the processing system 100 is removably received by the receiving device 3 of the electrical processing device 1, so that the output device 5 of the electrical processing device 1 automatically outputs the message M to the user only when the received battery pack B is removed from the receiving device 3.

[0036] A method according to the invention serves for assembling and—alternatively or additionally—disassembling the processing system 100. The method comprises a step according to which the electrical battery pack B of the processing system 100 is picked up by means of the receiving device 3, in particular in the picking direction A. Alternatively or additionally, the method comprises a step according to which the picked up electrical battery pack B is removed from the receiving device 3, in particular counter to the picking direction A. The method also has a step according to which the message M is automatically output by means of the output device 5 of the electrical processing device 1 if no battery pack B is picked up by the receiving device 3.

[0037] Alternatively or additionally, the output device 5 can be configured to automatically output a different message to the user when the battery pack B is picked up by the receiving device 3.

[0038] The electrical processing device 1 can be designed as a power saw 2, as in the present case. The output device 5 is configured to output the message M only when no battery pack B is received by the receiving device 3. The message M can be output temporarily or, as in the present case, continuously, as long as no battery pack B is received by the receiving device 3. The output device 5 can be electrically, electromechanically or, as in accordance with the Fig. 1 to 4 - be purely mechanically designed.

[0039] The electrical processing device 1 can have a user-operable locking device 19 for releasably locking the received battery pack B on or in the receiving device 3, in particular without tools.

[0040] The electrical processing device 1 in the present case has a lever 6. The lever 6 can be designed to be battery pack-actuated, i.e., the lever 6 can be actuated by means of the battery pack B. The lever 6 is pivotally mounted relative to the receiving device 3. In the present case, the lever 6 is pivotally mounted relative to the receiving device 3 about a lever axis HA of the lever 6, wherein the lever axis HA runs perpendicular to the receiving direction A and perpendicular to a longitudinal extension direction LE of the electrical processing device 1. Alternatively, the lever axis HA can run perpendicular to the receiving direction A and parallel to the longitudinal extension direction LE.

[0041] The lever 6 has a swivelled-out position PA (see Fig. 1 and Fig. 4). In the pivoted-out position PA, a free end portion 7 of the lever 6 protrudes transversely to the receiving direction A beyond the receiving recess 4. Alternatively or additionally, the free end portion 7 of the lever 6 can protrude transversely to the receiving direction A into the receiving recess 4.

[0042] The lever 6 also has a pivoted-in position PE (see Fig. 2). In the pivoted-in position PE, the free end section 7 is displaced by means of the accommodated battery pack B, as can be seen particularly in conjunction with the Fig. 2 and Fig. 3. In this case, the end section 7 can be displaced by means of the received battery pack B in the pivoted-in position PE in such a way that the free end section 7 is placed on an inner side 8 of a battery compartment 9 of the receiving device 3 along the receiving direction A, in particular flush.

[0043] For example, the lever 6 can be pivoted from the pivoted-out position PA into the pivoted-in position PE by means of the battery pack B. In the present case, the lever 6 can be pivoted in when and—alternatively or additionally—by the battery pack B being picked up. The lever 6 can be pivoted out from the pivoted-in position PE into the pivoted-out position PA as in the present case, for example automatically. For example, the lever 6 can be pivoted out when and—alternatively or additionally—by the picked-up battery pack B being removed from the receiving device 3.

[0044] The electrical processing device 1 has, for example, an elastically deformable pretensioning device 10. By means of the pretensioning device 10, the lever 6 can be pretensioned into the pivoted-out position PA, for example, in a self-resetting manner.

[0045] The free end section 7 of the lever 6 in this case carries a label 11 of the output device 5. For example, the label 11 is carried integrally by the end section 7. The label 11 can display the message M. In this case, the label 11 is carried by the free end section 7 in such a way that the current position of the lever 6 relative to the receiving device 3 is transmitted, in this case directly, to the label 11.

[0046] The lever 6 and—alternatively or additionally—the plate 11 can have a sliding contour 20. The sliding contour 20 can serve to contact the battery pack B when picking up and—alternatively or additionally—when removing the battery pack B from the receiving device 3. The sliding contour 20 can have a radius section, for example, an integrally formed one. The radius section can be advantageous with regard to frictional forces acting between the sliding contour 20 and the battery pack B. In particular, the sliding contour 20 is raised relative to a region of the plate 11 bearing the message M, so that this region of the plate 11 does not make sliding contact with the battery pack B, particularly when picking up and / or removing the battery pack B. In this way, abrasion of the region of the plate 11 bearing the message M can be reduced or even completely avoided.The sliding contour 20 may alternatively or additionally have a rotatable roller and / or a rotatable wheel.

[0047] In this case, the receiving device 3 has a receiving opening 12. The receiving opening 12 opens the receiving recess 4 outwards, counter to the receiving direction A. The battery pack B to be received can be inserted through the receiving opening 12 into the receiving recess 4 in the receiving direction A. It is understood that the battery pack B can also be removed from the receiving device 3 through the receiving opening 12 out of the receiving recess 4, counter to the receiving direction A.

[0048] The dispensing device 5, in this case the plate 11 of the dispensing device 5, can be configured to automatically cover the receiving opening 12 at least partially, in particular not completely or completely, when no battery pack B is received by the receiving device 3. According to Fig. 1, the shield 11 is configured not to completely cover the receiving opening 12 when no battery pack B is received by the receiving device 3. For example, the output device 5 is configured to exclusively cover the receiving opening 12 as long as no battery pack B is received.

[0049] The sign 11 can be provided primarily to cover the receiving opening 12, wherein the displayed message M is empty. Such an empty message M can, for example, be displayed exclusively by the position of the sign 11 relative to the receiving device 3, in particular wherein the empty message M does not include any characters or—alternatively or additionally—graphics or—alternatively or additionally—pictograms.

[0050] For example, the electrical processing device 1 has two output devices 5, as can be seen in particular from Fig.4. The two output devices 5 can be arranged opposite one another perpendicular to the recording direction A. In this case, the two output devices 5 are configured to jointly output the message M. Alternatively or additionally, the two output devices 5 can be coordinated with one another to jointly output the message M. The two output devices 5 can be designed and / or arranged mirror-symmetrically and / or point-symmetrically when viewed along the recording direction A.

[0051] The electrical processing device 1 in this case has an electrical drive device 13. The electrical drive device 13 is designed to generate drive power for a tool device 14 that can be attached to the electrical processing device 1. The tool device 14 can be detachably attached to the electrical processing device 1. The electrical processing device 1 in this case has a tank 15. The tank 15 defines a tank interior 16 of the electrical processing device 1 for storing a lubricant for lubricating the attached tool device 14. In this case, the lever 6 is configured to activate the lubrication when the battery pack B is inserted and—alternatively or additionally—to deactivate the lubrication when the battery pack B is not inserted. The activation of the lubrication and—alternatively or additionally—the deactivation of the lubrication can be positively controlled by adjusting the lever 6.“Deactivating lubrication” can be understood as a synonym for “interrupting the lubricant supply for lubrication.” “Activating lubrication” can be understood as a synonym for “releasing the interruption of the lubricant supply for lubrication.” The lever 6 can thus fulfill a dual function, namely, on the one hand, carrying the plate 11 and, on the other hand, activating and / or deactivating the lubrication. The interruption of the lubricant supply depending on the position of the lever 6 relative to the receiving device 3 can serve to counteract a leakage of the lubricant when the battery pack B is removed. For example, the lubricant supply is interrupted in the pivoted-out position PA of the lever 6, whereas the interruption of the lubricant supply is canceled in the pivoted-in position PE of the lever 6.

[0052] Message M may include an instruction regarding refilling the lubricant. Alternatively or additionally, message M may include a further instruction regarding a position of a filler opening 17 of tank 15, in particular relative to receiving device 3. Alternatively or additionally, message M may include a further instruction regarding a maintenance and / or servicing and / or adjustment and / or inspection measure, in particular for the tool device 14 attached to electrical processing device 1. Message M with the instruction regarding a maintenance and / or servicing and / or adjustment and / or inspection measure may relate to the chain tension of a saw chain 18 provided by the attached tool device 14. The instruction may be visualized textually and / or graphically in message M.

[0053] In embodiments not shown, the dispensing device 5 can have a, in particular different, shield 11 that can be adjusted, in particular linearly, along the receiving direction A by means of the battery pack B. The, in particular different, shield 11 has a first position relative to the receiving device 3, in which it covers the receiving recess 4, in particular at a receiving opening 12 of the receiving device 3. The, in particular different, shield 11 also has a second position relative to the receiving device 3, in which it is displaced in the receiving direction A by means of the received battery pack B. The, in particular different, shield 11 can be prestressed, in particular self-resetting, into the first position by means of a, in particular different, elastically deformable prestressing device 10 of the electrical processing device 1.
