Depth gauge
► Fig.15: 1. Depth gauge
The depth gauge is convenient for drilling holes of
uniform depth. Loosen the side grip and insert the depth
gauge into the hole in the side grip. Adjust the depth
gauge to the desired depth and tighten the side grip.
NOTE:
• The depth gauge cannot be used at the position
where the depth gauge strikes against the gear
housing.
Dust cup
► Fig.16: 1. Dust cup
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.
Dust cup 5
Dust cup 9

OPERATION

Hammer drilling operation
► Fig.17
Set the action mode changing knob to the
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 rein-
forcing 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)
► Fig.18: 1. Blow-out bulb
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.

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.
