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 (optional accessory) (Fig. 22)
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
006406
There is another type of dust cup (optional 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 (optional
accessory)
Before installing the dust cup, remove the bit from the
tool if installed on the tool. Install the dust cup (optional
accessory) on the tool so that the
cup is aligned with the grooves in the tool. (Fig. 23)
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. (Fig. 24)
And then grab the attachment at the foot of dust cup and
take it out. (Fig. 25)
NOTE:
• When installing or removing the dust cup, the cap may
come off the dust cup. At that time, proceed as follows.
Remove the bellows from the attachment and fit the
cap from the side shown in the figure with its flat 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. 26, 27 & 28)
NOTE:
• If you connect a vacuum cleaner to your hammer,
cleaner operations can be performed. Dust cap needs
to be removed from the dust cup before the connection.

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 (Fig. 30)
CAUTION:
• There is 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 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.

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.
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. 31)
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.
Drilling in wood or metal
CAUTION:
• Never use "rotation with hammering" when the quick
change drill chuck is installed on the tool. The quick
change drill chuck may be damaged.
Also, the drill chuck will come off when reversing the
tool.
• Pressing excessively on the tool will not speed up the
drilling. In fact, this excessive pressure will only serve
to damage the tip of your bit, decrease the tool
performance and shorten the service life of the tool.
• There is a tremendous twisting force exerted on the
tool/bit at the time of hole breakthrough. Hold the tool
firmly and exert care when the bit begins to break
through the workpiece.
• A stuck bit can be removed simply by setting the
reversing switch to reverse rotation in order to back
out. However, the tool may back out abruptly if you do
not hold it firmly.
• Always secure small workpieces in a vise or similar
hold-down device.
Set the action mode changing knob to the
You can drill up to 13 mm diameter in metal and up to
32 mm diameter in wood.
For Model HR2631F, HR2641, HR2630
Use the drill chuck assembly (optional accessory). When
installing it, refer to "Installing or removing the bit"
described on the previous page. (Fig. 33)
To install the bit, place it in the chuck as far as it will go.
Tighten the chuck by hand. Place the chuck key in each
of the three holes and tighten clockwise. Be sure to
tighten all three chuck holes evenly.
To remove the bit, turn the chuck key counterclockwise in
just one hole, then loosen the chuck by hand. (Fig. 34)
For Model HR2631FT, HR2320T, HR2630T
Use the quick change drill chuck as standard equipment.
When installing it, refer to "changing the quick change
chuck for SDS-plus" described on the previous page.
