| Symptom | Manual Section | Unwritten Fix | |--------|---------------|----------------| | Trigger jams or won't lock | Page 8 (Trigger lock) | The internal trigger rod deforms. Disassembly: remove 4 long screws, lift top cover. Clean old grease. Do not lubricate trigger switch itself (dry contact). Replace switch if arcing visible. | | Variable speed stuck on max | Page 10 (Speed control thumbwheel) | The potentiometer wiper inside the thumbwheel cracks. "Fixed" means soldering a 100k linear pot from an electronic parts store (Bosch original not available). Epoxy it into the wheel housing. | | Blade won't stay clamped | Page 12 (SDS clamp) | The clamp lever spring breaks. Manual says "replace lower blade holder assembly (part 2 609 200 435)". Reality: you can fix it using a 5mm E-clip and a modified ballpoint pen spring as a temporary field repair. | | No pendulum action | Page 14 (Orbital adjuster) | The plastic cam inside the gear housing cracks. You must disassemble, clean metal shavings, and glue with epoxy putty (e.g., JB Weld). Manual omits that the cam must be re-greased with lithium complex grease (not general purpose). | | Carbon brushes arcing | Page 40 (Brush replacement) | Manual says "replace when below 5mm." It doesn't stress that you must also clean the commutator with a fine eraser or 600-grit sandpaper and blow out carbon dust. Failure to do this burns the new brushes in 2 hours. | You mostly cut wood (softwood, plywood, construction lumber)
