OPERATION

Hammer drilling operation

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.

First, turn the action mode changing ring so that the

arrow on the tool body points to the

adjusting ring can be aligned in any torque levels for this

operation.

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.
