Set the change lever and the shift 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 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:
• 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.

After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.

Set the change lever and the shift 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.

Use the optional drill chuck assembly. When installing it,
refer to "Installing or removing the bit" described on the
previous page.
Set the change lever and the shift lever to the
symbol.
You can drill up to 13 mm diameter in metal and up to 30
mm diameter in wood.
CAUTION:
• Never use "rotation with hammering" when the drill
chuck assembly is installed on the tool. The drill
chuck assembly may be damaged.
Drilling in wood
• When drilling in wood, best results are obtained
with wood drills equipped with a guide screw. The
guide screw makes drilling easier by pulling the bit
into the workpiece.
Drilling in metal
• To prevent the bit from slipping when starting a hole,
make an indentation with a centerpunch and
hammer at the point to be drilled. Place the point of
the bit in the indentation and start drilling. Use a
cutting lubricant when drilling metals. The
exception is brass which should be drilled dry.
CAUTION:
• Pressing excessively on the tool will not speed up
the drilling. In fact, this excessive pressure will only
