    Default hammers only when started several times

    Hey BUBBA,
    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..
