check fuel filter it may be only getting enough fuel to run up to so many rpm

Order an maintenance kit for it , when the working hours are on the tool , all given parts in the kit must be replaced its not a good idea to only grease it, the tool should not leaking by the chisel. then there will be a bad break-force and give a long working job..

If selled some capacitor or new ignition parts order it always with statement of the serial motornumber and the year of build , because of modifications on marketing technical dicisions can be made for your engine, that can prevent a next disappointment. may be for the problem a new sparkplug the supression capacitor can also be bad a bad sparkplug connection cable .are some small sugestions.

This is a possible problem. Check and see if the compressor has a fuse in it. If you have the manual it will tell you if it has a reset fuse if not check and see if the outlet there’s a fuse. I’ve had the same problem with the one I have. Hopefully it works if it doesn’t I’m sorry

Replace the "O" ring seals.

One of the first things that you want to check, is the wire connections above the light that is flickering. It would be a good idea to check the first light also, and the switch connections, due to the age of the wiring. If all this fails, then you are probably right and the socket of the flickering light should be changed.
It would not hurt to go in grids and work your way thru the house, checking the wiring and tightening the wire nuts, or connectors.
Enjoy :)

Beware Time for service something does blocking the armature if that happens a bearing or other broken part.

First to look for faultering contacts on electric field and carbon brushes sometimes a suppression capacitor can give some problems a worn commutator on the armature a switch can be overhauled with a direct cable contact to test to know if it is the switch test it out only with 2 persons for safety in that case.

Bosch Parts Service Online Illustrated Part List Control the power cable for wire breakage second remove the carbon brushes and control them on the collector surface for if there is a little black pin was coming out of it thats an auto protection build in then replace the brushes , but there are more things because there can be a problem with the electric field on a contact measure both coils and all the collectors (commutator around) on the armature that there is no-one lost the last option is the electronics

It probably went on strike to demand more money and/or more benefits.

demolition hammers require hydraulic oil in most cases.
Any good tool shop should have hydraulic oil to suit.

Position 856 1617000836 a broken hammer piston in the worst case but you have to order 1 617 000 A15 a maintence kit and special lubrication used 50 ml 1 615 437 512 INSPECT CAREFULLY THE 1 617 000 838 Hammer Pipe for rips if all parts are unmounted of the hammer pipe tap it with a metal object then it should not have any dull sound treat like a tuning fork for control for rips. thats important before repair consideration before.
