try asking the place you bought it

The o-rings are most likely worn out. Take it to a service center and have them diagnose it. It probably needs a service kit installed.

How can i see the previous answers ?

Makita A-90582 or (the equivalent)

Hitachi 981840 Hammer Grease

But dont forget to replace all o-rings and seals at the same time some older models have special wear tear parts sets for service also called maintenance spare parts. If the brushes are short then its time for service.

Lack of oil in the gearbox.

Ureythn GE00 is madr by Fuchs in Germany - see their website.
Darina is made by Shell - see internet for comparable grease

get a multi-meter and test switch and wiring

no information generic answer --notify the manufacturer or owners manual for assistance

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

I think there is some faults to cause the generator stop, focus on checking the oil circuit, gas path and generator load. https://www.dieselgeneratortech.com/diesel-generators/faults-caused-by-low-load-operation-of-diesel-generator.html

If an oil sight glass is in the modelrange of the brand ROK Rottela 40 , but if no sight glass is used in the model then often is to use special Grease lubrication. or only an special volume of oil and most used of them are zinc-free hydraulic based and included in the manual instructions of a maintenance set (service kit)wear parts set.

If it's like mine, it probably won't charge. First time I let it run down, it was screwed, a real POS.

3 to 4 ounces for first fill. You actually unscrew the oil gauge with the little wrench that should have come with the tool and add the oil there. After putting the cap back on, hold the tool upright to check the oil level. Check daily and add oil when the level drops to 1/4 when checking as described above.

Hello,

You can try to watch this video: https://youtu.be/udj28_tLJvU

Dont forget to lubricate o-rings when mounting parts in. For flat x rings you can hold then in hot water to make them softer and thrn put ring in a place

You need to check armature gear it can be damaged. Connection rod can be broken or you just need new o-rings and grease

A dangerous work wear safety glasses and a leather apron because there could be metal pieces come off the parts , make first the part the disassembled toolholder hot with a large gas burner and in a bench vise with a hammer Interim anything like WD40 spray. sometimes it could be a long prolonged work if you have inserted an invalid chisel.
