The bit can be secured at 24 different angles. To change
the bit angle, depress the lock button and rotate the
change lever so that the pointer points to the
symbol.
Turn the bit to the desired angle.
Depress the lock button and rotate the change lever so
that the pointer points to the
symbol. Then make sure
that the bit is securely held in place by turning it slightly.
Depth gauge

008546
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.
Dust cup
1
001300
Use the dust cup to prevent dust from falling over the tool
and on yourself when performing overhead drilling
operations. Attach the dust cup to the bit as shown in the
figure. The size of bits which the dust cup can be
attached to is as follows.
Bit diameter
Dust cup 5 6 mm - 14.5 mm
Dust cup 9
12 mm - 16 mm

OPERATION
CAUTION:
• Always use the side grip (auxiliary handle) and
firmly hold the tool by both side grip and switch
handle during operations.
Hammer drilling operation
008547
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 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
