OPERATION
Hammer drilling operation
009131
Set the action mode changing knob 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 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.
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.
NOTE:
Eccentricity in the bit rotation may occur while operating the
tool with no load. The tool automatically centers itself during
operation. This does not affect the drilling precision.
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 action mode changing knob 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.

Use the optional drill chuck assembly. When installing it,
refer to "Installing or removing the bit" described on the
previous page.
Set the action mode changing knob so that the pointer
points to the
symbol.
CAUTION:
•
Never use "rotation with hammering" when the drill
chuck assembly is installed on the tool. The drill
chuck assembly may be damaged. Also, the drill
chuck will come off when reversing the tool.
•
Pressing excessively on the tool will not speed up the
drilling. In fact, this excessive pressure will only serve
to damage the tip of your bit, decrease the tool
performance and shorten the service life of the tool.
