Question about Electric Demolition Jackhammer
To trouble shoot, easiest to hardest:
1. Check both brushes, they should be 1/4" long or more and evenly worn, the spring should push carbon firmly against armature. If there is a small pin pushing out of the center of the brush it is worn too far and needs to be replaced. The pin is designed to push excessively worn brushes off the armature so as not to damage it. >
2. Check for power at cord going into the switch with a multimeter, if 0V replace the cord, if 110V; push trigger and check for power coming out of the switch, if 0V replace the switch, if 110V >
3. If these are all OK you need to check the armature on a growler to see if it's OK.
