(4) Removing dust
Excessive dust in the dust box will reduce dust-collecting
eff ectiveness. Empty the dust box regularly.
Push the lever to remove the dust box from the dust-
collecting unit, and empty and clean the box (Fig. 13).

(5) Replacing the rubber cap
Wear of the rubber cap will reduce dust-collecting
eff ectiveness.
Replace the rubber cap when it becomes worn.
How to replace the rubber cap (Fig. 14)
(1) Remove the nozzle seal from the nozzle.
(2) Replace the rubber cap with a new cap.
Fit the rubber cap making sure that it is correctly oriented.
(3) Attach the nozzle seal.
Insert the lip of the nozzle seal securely into the groove of
the nozzle.
At this time, make sure that the groove between the
nozzle and the nozzle seal is uniform all the way round.
4. When not using the dust-collecting unit
When using the rotary hammer without the dust-collecting
unit, attach the provided cover in the unit attachment hole
(Fig. 15).
CAUTION
If no cover is attached, dust or other particles may be
sucked up from the hole, causing damage to the motor.
5. Rotation only
NOTE
The dust-collecting unit cannot be used. Remove the unit
and attach the provided cover in the unit attachment hole.
CAUTION
If no cover is attached, dust or other particles may be
sucked up from the hole, causing damage to the motor.
This rotary hammer can be set to rotation only mode by
pressing the push button and turning the change lever to
the mark. (Fig. 16)
Turn the grip slightly and confi rm that the clutch has been
engaged with a click.
To drill wood or metal material using the drill chuck
and chuck adapter (optional accessories), proceed as
follows.
Installing drill chuck and chuck adapter: (Fig. 17)
(1) Attach the drill chuck to the chuck adapter.
(2) The part of the SDS-plus shank is the same as the drill
bit. Therefore, refer to the item of "Mounting the drill bit"
for attaching it.
CAUTION
○ Application of force more than necessary will not only
expedite the work, but will deteriorate the tip edge of the
drill bit and reduce the service life of the rotary hammer in
addition.
○ Drill bits may snap off while withdrawing the rotary
hammer from the drilled hole. For withdrawing, it is
important to use a pushing motion.
○ Do not attempt to drill anchor holes or holes in concrete
with the machine set in the rotation only function.
Dust-collecting eff ectiveness is reduced if the fi lter in the
dust box becomes blocked.
Use the table below as a guide to replacement of the dust
box.
Drill diameter of 6 mm / depth of 28 mm: 130 holes
Drill diameter of 8 mm / depth of 30 mm: 75 holes
Drill diameter of 12 mm / depth of 50 mm: 20 holes
Dust box has been fi lled and emptied 100 times
○ Do not attempt to use the rotary hammer in the rotation
and hammering function with the drill chuck and chuck
adapter attached. This would seriously shorten the
service life of every component of the machine.
6. When driving machine screws (Fig. 18)
First, insert the bit into the socket in the end of chuck
adapter (D).
Next, mount chuck adapter (D) on the main unit using
procedures described in 4 (1), (2), (3), put the tip of the
bit in the slots in the head of the screw, grasp the main
unit and tighten the screw.
CAUTION
○ Exercise care not to excessively prolong driving time,
otherwise, the screws may be damaged by excessive
force.
○ Apply the rotary hammer perpendicularly to the screw
head when driving the screw; otherwise, the screw head
or bit will be damaged, or driving force will not be fully
transferred to the screw.
○ Do not attempt to use the rotary hammer in the rotation
and hammering function with the chuck adapter and bit
attached.
7. When driving wood screws (Fig. 18)
(1) Selecting a suitable driver bit
Employ plus-head screws, if possible, since the driver bit
easily slips off the heads of minus-head screws.
(2) Driving in wood screws
○ Prior to driving in wood screws, make pilot holes suitable
for them in the wooden board. Apply the bit to the screw
head grooves and gently drive the screws into the holes.
○ After rotating the rotary hammer at low speed for a while
until the wood screw is partly driven into the wood,
squeeze the trigger more strongly to obtain the optimum
driving force.
CAUTION
Exercise care in preparing a pilot hole suitable for
the wood screw taking the hardness of the wood into
consideration. Should the hole be excessively small or
shallow, requiring much power to drive the screw into
it, the thread of the wood screw may sometimes be
damaged.
8. Hammering only
NOTE
The dust-collecting unit cannot be used. Remove the unit
and attach the provided cover in the unit attachment hole.
CAUTION
If no cover is attached, dust or other particles may be
sucked up from the hole, causing damage to the motor.
This rotary hammer can be set to hammering only mode
by pressing the push button and turning the change lever
to the mark (Fig. 19).
