Depth gauge
The depth gauge is convenient for drilling holes of uniform depth. Loosen the
clamp screw and adjust the depth gauge to the desired depth. After adjusting,
tighten the clamp screw firmly.
NOTE:
• The depth gauge cannot be used at the position where the depth gauge
strikes against the gear housing/motor housing.
OPERATION
Hammer drilling operation
Set the change lever to the symbol.
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.
CAUTION:
• When the bit begins to break through concrete or if the bit strikes
reinforcing rods embedded in concrete, the tool may react dangerously.
Maintain good balance and safe footing while holding the tool firmly with
both hands to prevent dangerous reaction.
Blow-out bulb (optional accessory)
After drilling the hole, use the blow-out bulb to clean the dust out of the hole.
Chipping/Scaling/Demolition
Set the change lever to the symbol.
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.
