Question about Bosch 15.0 Amp Brute Breaker Hammer With Service Minder Shock Mounted Handl
I own a Bosch Brute hammer that runs good, just will not hammer with any force. Can you let me know what I need to do to fix the problem. I have torn the unit apart, and looked at the cylinder/driver assembly. Everything looks correct, but it still does not work. Can you let me know what I need to look for? Let me know. Thanks,
What age is the machine? If it is fairly new it might just need to be run a while for the grease to loosen up. If it is older you will need to make sure it has enough grease. These tools don't need a great deal of grease, but too little will soon be thrown about and disperse too much. Another problem with these is if the inner cylinder, that moves up and down to create the pressure for teh striker, has a hairline crack, it can be quite hard to see when the part is dirty. When running though air will leak out and you will loose hammer action but still have plenty of vibratiion. Another thing to check is to take the piston/cylinder and striker out and hold it facing down. The striker should slide out slow and steady. If it falls out too fast then the cylinder and/or striker is worn. You may be able to rectify this by applying a bit more grease. If it doeesn't fall out at all then there is a build of grease behind the striker causing a vacum holding it all together. You can solve this by pushing the striker in a little way, and leaving it standing for an hour or so with cleaning solvent on top. It should work it's way in and help release it. It may still need to be 'persuaded' out a bit aswell.
