Reply: 11220evs Hammers Sometimes
Usually the tool will develop a 'dry' pocket where the striker loses its ability to move inside the chamber to create the percussion..:) in other words its probably time to service..a service pack is available..# 1617000263 it has all the o-rings,brushs,etc..check out the link
not aware of a video at this time..
hope this helps..
