The depth gauge is convenient for drilling holes of uniform depth. Loosen the

The depth gauge cannot be used at the position where the depth gauge

strikes against the tool body.

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, or when striking 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

lever to the position of

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 posi-

tion 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.
