Depth gauge
1
The depth gauge is convenient for drilling holes of uni-
form depth. Insert the depth gauge into the hole in the
grip base. Adjust the depth gauge to the desired depth
and then tighten the clamp screw to secure the depth
gauge.
NOTE:
The depth gauge cannot be used at the position
where the depth gauge strikes against the tool
body.
OPERATION
Hammer drilling operation
Set the change lever to the
Position the bit at the desired location for the hole, then
pull the switch trigger. Do not force the tool. Light pres-
sure gives best results. Keep the tool in position and pre-
vent 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.

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.
Blow-out bulb (optional accessory)
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.

Hold the tool firmly with both hands. Turn the tool on and
apply slight pressure on the tool so that the tool will not
bounce around, uncontrolled. Pressing very hard on the
tool will not increase the efficiency.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.
