Where do I put the oil?

Most breaker hammers have no oil if they have no high speed.
But special grease with high thermal conductivity.
very important .
If there is loose grease buy a consumables kit only complete , only then it makes sense.

Bosch gbh5 will keep loosing its hammer

It sounds like the gearbox oil is getting low. The GBH5 uses oil in the gearbox, not a grease - the grease is used for assembly only. The correct type is a PG-150 (fully synthetic gear oil). Unable to find it in small quantities, I now use PAG150 oil for automotive a/c systems, it's available in small bottles. As for quantity, no-one seems to know... I just fill to cover the big bottom gears.

What is this on? If it is a breaker, the grease is to coat the feed wires to keep the corrosion and resistance down

this tool does not require daily maintenance, but if the grease needs to be refilled it takes 60g/2oz of hammer grease part number A-90582. This is packaged in 1oz tubes. They also show oil and that part number is 181118-7. If you go to their site "" you can download or look at the section on maintenance and it shows you how to fill the reservoir. Good luck.

Best practice is to purchase service kit part # 1617000050 . It is available from several outlets including link below. The kit includes items that need to be replaced at time of lubrication.
If you do not want to purchase the kit then use Bosch 1615430015 Hammer Grease 15oz

How do I drain the gear oil from a Bosch Brute Jack Hammer

Brute hammer uses special grease sold as service kit. This kit contains enough grease to lube hammer and replacement bolts that hold springs along the bottom. Check for parts and kit. Remove the lower half (tube) of hammer, also remove three bolts that hold springs and remove assembly from tube. Wash out old grease. Grease will be oil-like only when hammer is very hot, otherwise grease is paste-like. Good luck.

Bosch Breaker Hammer Service Kit Install

The grease in the upper drive area used to be a purple looking grease and the grease in the barrel was a different color and weight. If you ordered the rebuild kit with the O rings and bolts I would use it in the barrel (light film coat on the parts )
