○ When turning the rotary hammer on while dust collector
(B) is detached from a concrete surface, dust collector
(B) will rotate together with the drill bit. Make sure to turn
on the switch after pressing the dust cup on the concrete
surface. (When using dust collector (B) attached to a
drill bit that has more than 190 mm of overall length,
dust collector (B) cannot touch the concrete surface
and will rotate. Therefore, please use dust collector (B)
by attaching to drill bits which have an overall length of
166 mm or less.)
○ Dump particles after every two or three holes when
drilling.
○ Please replace the drill bit after removing dust collector
(B).

HOW TO USE
CAUTION
To prevent accidents, make sure to turn the switch
off and disconnect the plug from the receptacle when
the drill bits and other various parts are installed or
removed. The power switch should also be turned off
during a work break and after work.
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.
Continuous operation may be attained by pulling the
trigger switch and depressing the stopper. To turn the
switch OFF, pull the trigger switch again to disengage
the stopper, and release the trigger switch to its original
position.
However, the switch trigger can only be pulled in
halfway during reverse and rotates at half the speed of
forward operation.
The switch stopper is unusable during reverse.
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

mark (Fig. 6).
(1) Mount the drill bit.
(2) Pull the trigger switch after applying the drill bit tip to the
drilling position (Fig. 7).
(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. 7.
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. 8).
