Keep the tool in position and prevent it from the slipping away from the hole.
Do not apply more pressure when the hole becomes clogged with clips 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 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.
DRILLING IN WOOD OR METAL
Use the optional drill chuck assembly. When installing it, refer to “installing or
removing the bit” described on the previous page.
