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.

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. The lubricant will be quite thick and that can also be the case only , (only have had its working hours on it) the revision of this hammers are easy to do it yourself clean solvent all metal parts that you re-use again to do the job you have a bench-vise and tools , for the striker pin in case there are no special tools neccesary like other hammers like a suggestion the Milwaukee 500S or other proffesional hammer because of the need of special seals and tools are neccesary , in between 1 and 2 hours are taken to service this Bosch hammers sometimes its neccesary to be aware of 1 ring to replace first of all because its easy to forget this ring on position 104 1610210095 o-ring that will very easy forgotten in practise with some grease replace it first of all spare parts.

Striker pin problem / broken connecting rod OR 1 o-ring 1 610 210 195 pos 165 thats become soft and not round anymore that will lock the striker in the sleeve when the lubrication gets older The most caused suggestions but a cylindrical gear thats broken is rare http://www.powertools-aftersalesservice.com/public/bosch-pt/service?p_auth=qwTIfM5m&p_p_auth=fCklnOO5&p_p_id=WSRP_bc93764e__6873__4b00__9a29__b331c9759da9&p_p_lifecycle=1&p_p_state=normal&p_p_mode=view&_WSRP_bc93764e__6873__4b00__9a29__b331c9759da9_wsrp-navigationalState=L0JPUy9QVEFTLVBULVNJUy1TaXRlL2VuX1VTLy0vVVNEL1ZpZXdQcm9kdWN0LURpc3BhdGNoO3BnaWQ9YmNkZTdkNTFiZjM0NGE0YTU1ZjYzYTYyOGY0Mi1yM1JtZlhPO3NpZD1ySWdEM2JoYjhNb25oZUR1YVZRZkpyZlF1a093UDNGQU5vbUFkanI3WlpPWjNLNlFIMm89

There is no grease but oil used in this tool There is a special consumables kit for to order But BEFORE you made a self service for this machine there could be a rip somewhere in the spindle control first by ringing listen to the sound tap on it it with a piece of metal that the spindle sounds well without also all in and outside parts naturally and off if it does is the sds chisel drill conduction inside the spindle is not round toppen instead of square topped because of faultering on the chisel or drill in short time to expect. in that case if the spindle is bad its better to remplacement the whole tool by Bosch for the working hours on all parts are reached, but if the spindle is smooth order 1 615 437 511 oil reservoir and 1 617 000 A16 thats the right maintenance partsset for this machine and its is easy to service by yourself a little 2 or 3 hours without special tools for special kevlar rings like some other brands often have. but a bank vice and some little screwdrivers noseplier, shaft retaining ring pliers a solvent cleaner for the old lubrication to remove. AND IMPORTANT dont forget part 104 best to give that o-ring some grease that it will not move out by insert the spindle (sometimes) one thing is very important there must inside be 2 adjust rings between the gears 47 and 51 if there is only one shimring = used then order some shim rings ( there must be made an adjust between 0,08 and 0,22 mm between the gears tooth but only when there is only 1 ring was used that can be happen in a rare case. the drawing is to find also by bosch in america the partnumbers are the same. http://www.powertools-aftersalesservice.com/public/boschprof/service?p_auth=ZdEJ7pFj&p_p_auth=R78yYhDo&p_p_id=WSRP_bc93764e__6873__4b00__9a29__b331c9759da9&p_p_lifecycle=1&p_p_state=normal&p_p_mode=view&_WSRP_bc93764e__6873__4b00__9a29__b331c9759da9_wsrp-navigationalState=L0JPUy9QVEFTLVBULVNJUy1TaXRlL25sX05MLy0vRVVSL1ZpZXdQcm9kdWN0LURpc3BhdGNoO3BnaWQ9YmI5NWI3MGRjM2E3NzQxY2ExYzA0OGYyM2IzMDdhNWQ4RkJCO3NpZD1Zdks0RVZOU3dzVm1OZ3M3YnNlazZselpkRGtMODVwSi1QTTd1dEh5ZERrTDg1cEotUE09
