Piston travels, but...
Question by Carl

Hi. My Bosch 11305 demo hammer seems to be in basically good order, but the tool is not being impacted by the impact bolt. I have confirmed that the piston is shooting in and out just fine (motor, gears, piston all good) but it is as though the impact bolt striker are not long enough to reach the base of the tool. Ideas?

Question by Doug C

How much oil is needed from the service pack I received. Is the oil poured into the chamber noted
on Fig//abb.1 # 828

Leaking fluid
Question by Paul D

I went to use my Bosch jackhammer after lengthy storage and I see evidence of an oil leak on the lower body. Is this fluid I need to top off and/or replace O rings?
