发明名称 Portable handheld work apparatus and method of making the same
摘要 A portable handheld work apparatus has at least one work tool which is driven by an internal combustion engine (2). The engine (2) has a crankcase (20) which is formed, at least in part, by a crankcase sump (28). The work apparatus has a housing component (4) of plastic. The crankcase sump (28) is made of metal and is injection molded into the housing component (4) of the work apparatus. The engine (2) has an ignition unit which includes an ignition module (31). A simple configuration of the work apparatus results when the ignition module (31) is fixed directly and electrically conductively to the metal crankcase sump (28). For making the work apparatus, at least one attachment element for attaching a work tool carrier is fixed on the crankcase sump (28) before the crankcase sump (28) is injection molded therearound by the material of the housing component (4).
