OPERATION

Hammer drilling operation
002447
CAUTION:
There is a tremendous and sudden twisting force
•
exerted on the tool/bit at the time of hole
break-through, when the hole becomes clogged
with chips and particles,
reinforcing rods embedded in the concrete. Always
use the side grip (auxiliary handle) and firmly hold
the tool by both side grip and switch handle during
operations. Failure to do so may result in the loss
of control of the tool and potentially severe injury.
When drilling in concrete, granite, tile, etc., turn the
action mode changing knob to the position of
to use "rotation with hammering" action.
Be sure to use a tungsten-carbide tipped bit.
Position the bit at the desired location for the hole, then
pull the switch trigger. Do not force the tool. Light
pressure gives best results. Keep the tool in position and
prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at
an idle, then remove the bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
