Embodiment Construction

[0033] figure 1 A power saw 1 is shown schematically as an example of a hand power tool. The power saw 1 has an internal combustion engine 2 arranged in a housing component 4 . The housing component 4 is designed as a motor housing and is closed by a housing cover 3 . The handle housing 12 is fastened to the motor housing via an anti-vibration element 13 . The handle housing 12 has a rear handle 5 and a handle tube 6 . Furthermore, a fuel tank 14 is fixed to the handle housing 12 . Advantageously, the fuel tank 14 is formed in one piece with the handle housing 12 and is integrated in the handle housing 12 .

[0034] The internal combustion engine 2 is designed as a single-cylinder motor, advantageously as a two-stroke motor. However, internal combustion engine 2 can also be designed as a four-stroke motor. The internal combustion engine 2 drives a drive pinion 7 on which the saw chain 8 is arranged. The saw chain 8 is guided on guide rails 9 . The guide rail 9 is faste...

Abstract

The present invention relates to a handheld machine tool which is provided with at least one cutter driven by an internal combustion engine (2), wherein the internal combustion engine (2) is provided with a crankcase (20) which is at least partially composed of an oil pan (28), wherein the machine tool comprises a housing component (4) which is made of plastic; the oil pan (28) is made of metal and is injected into the housing component (4) of the machine tool; the internal combustion engine (2) is provided with an ignition device which is provided with an ignition module (31). If the ignition module (31) is directly and conductively fixed to the oil pan (28) made of metal, a simple structure of the machine tool can be realized. For manufacturing the machine tool, the invention prescribes that: before injection and packing of the material of the housing component (4) are performed to the oil pan (28), at least one fixing component used for fixing the cutter rack is fixed to the oil pan (28).

Description

technical field [0001] The invention relates to a hand-held power tool of the type specified in the preamble of claim 1 and also to a method of the type specified in the preamble of claim 19 for producing a hand-held power tool. Background technique [0002] A motor saw is known from DE 103 93 139 T5, the metal oil sump of which is injected into the housing component. A section is integrally formed on this metal oil sump, to which a fastening element for fastening the guide rail is fastened. The guide rail rests against the metal oil sump here. [0003] The internal combustion engine in a hand tool machine is usually ignited from an external source and has an ignition system with an ignition module. This ignition module must be grounded. For this purpose, the ignition module is usually connected to the metal crankcase via connecting wires. Contents of the invention [0004] The object of the present invention is to create a hand-held power tool of the same type which h...
