Hammer drilling operation
.Position the drill bit a t the location for the hole, then pull the trigger.
Do not force the tool. Light pressure gives best results. Keep the tool in posi- tion and prevent it from slipping away from the hole.
When holes becomeclogged
.Do not apply more pressure when the hole becomes clogged with chips or par- ticles. Instead, run the tool a t idle, then remove from the hole. By repeating this several times, the hole will be cleaned out completely.

CAUTION:
When drilling in concrete, it is quite possible that the drill bit could hit a reinforcing rod or some other object that could cause a kickback. Although this tool is equipped with the torque limiter, protect yourself by holding the tool firmly with both hands. (Be sure the side grip is secured tightly before operation.)
