1. Switch operation
The rotation speed of the drill bit can be controlled
steplessly by varying the amount that the trigger switch
is pulled. Speed is low when the trigger switch is pulled
slightly and increases as the switch is pulled more.
2. Rotation + hammering
This rotary hammer can be set to rotation and
hammering mode by pressing the push button and
turning the change lever to the
the grip slightly and confi rm that the clutch has been
engaged with a click.
(1) Mount the drill bit.
(2) Pull the trigger switch after applying the drill bit tip to the
drilling position. (Fig. 4)
(3) Pushing the rotary hammer forcibly is not necessary
at all. Pushing slightly so that drill dust comes out
gradually is 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 grip the side handle and handle
tightly as shown in Fig. 4.
3. Rotation only
This rotary hammer can be set to rotation only mode by
pressing the push button and turning the change lever
to the mark. (Fig. 5)
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. 6)
(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.
○ 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.
4. When driving machine screws (Fig. 7)
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
5. When driving wood screws (Fig. 7)

(1) Mount the taper shank adapter to the rotary hammer.
(2) Mount the drill bit (taper shank) to the taper shank

screws.
suitable for them in the wooden board. Apply the bit to
the screw head grooves and gently drive the screws
into the holes.
while until the wood screw is partly driven into the
wood, squeeze the trigger more strongly to obtain the
optimum driving force.
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.
This rotary hammer can be set to hammering only mode
by pressing the push button and turning the change
lever to the

When you wish to change a position of the side handle,
turn grip of the side handle counterclockwise to loosen
it, and then fasten it fi rmly.
When boring a hole, there can be a case where the
machine attempts to rotate by the reaction at the time
of penetrating a concrete wall and/or when a tip of the
blade comes in contact with the rebar.
Firmly fasten the side handle and hold the machine
