the grip base 2. Toothed side of the depth
gauge
At this time, the depth gauge needs to be inserted so
that its toothed side is directed to the toothed side of
hex hole marking on the grip base as shown in the
figure.
► Fig.18: 1. Lock button
Adjust the depth gauge to the desired depth by moving
it back and forth while pressing the lock button. After the
adjustment, release the lock button to lock the depth
gauge.

NOTE:
• Inserting the depth gauge with its toothed side
not directed to the toothed side of hex hole
marking on the grip base as shown in the figure
does not allow the depth gauge to be locked.
Dust cup
► Fig.20: 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
There is another type of dust cup (accessory) which
helps you prevent dust from falling over the tool and on
yourself when performing overhead drilling operations.
Installing or removing the dust cup
► Fig.21: 1. symbol 2. Grooves 3. Dust cup
Before installing the dust cup, remove the bit from the
tool if installed on the tool. Install the dust cup (acces-
sory) on the tool so that the
is aligned with the grooves in the tool.
► Fig.22: 1. Bit 2. Chuck cover
To remove the dust cup, pull the chuck cover in the
direction as shown in the figure and with the chuck
cover pulled take the bit out of the tool.

NOTE:
• When installing or removing the dust cup, the
cap may come off the dust cup. At that time, pro-
ceed as follows. Remove the bellows from the
attachment and fit the cap from the side shown
in the figure with its carved side facing upward
so that the groove in the cap fits in the inside
periphery of the attachment. Finally, mount the
bellows that has been removed.
► Fig.27
NOTE:
• If you connect a vacuum cleaner to your ham-
mer, cleaner operations can be performed. Dust
cap needs to be removed from the dust cup
before the connection.

OPERATION

Always use the side grip (auxiliary handle) and firmly
hold the tool by both side grip and switch handle during
operations.
Hammer drilling operation
► Fig.28
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 pres-
sure 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.
Set the action mode changing knob to the
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)

dust out of the hole.
