(1) Mount the drill bit.
(2) Pull the trigger switch after applying the drill bit tip to
the drilling position. (Fig. 11)
(3) Pushing the rotary hammer forcibly is not necessary
at all. Pushing slightly so that drill dust comes out
gradually is just suffi cient.
CAUTION
When the drill bit touches construction iron
bar, the bit will stop immediately and the rotary
hammer will react to revolve. Therefore please
grip the side handle and handle tightly as shown
in Fig. 11.
3. Rotation only
Turn the change lever fully in the direction of the " "
mark to set "rotation only". (Fig. 10)
To drill a wood or metal material using the optional
drill chuck and chuck adapter, proceed as follows.
Installing drill chuck and chuck adapter : (Fig. 12)
(1) Attach the drill chuck to the chuck adaptor.
(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 work at all, but will deteriorate the
tip edge of the drill bit and reduce the service life
of the rotary hammer in addition.
● Drill bit 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 use the rotary hammer in
the rotation and striking mode with the drill
chuck and chuck adapter attached. This would
seriously shorten the service life of every
component of the machine.
4. When driving wood screws (Fig. 13)
(1) Selecting a suitable driver bit
Employ plus-head screws, if possible, since the driver
bit easily slips off the heads of slotted-head screws.
(2) Tightening wood screws
Prior to tightening 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
in the holes.

Chuck adapter
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.
5. Using depth gauge (Fig. 14)
(1) Loosen the knob on the side handle, and insert the
depth gauge into the mounting hole on the side
handle.
(2) Adjust the depth gauge position according to the
depth of the hole and tighten the knob bolt securely.
