CAUTION
䡬
The dust cup and dust collector (B) are for exclusive
use of concrete drilling work. Do not use them for
wood or metal drilling work.
䡬
Insert dust collector (B) completely into the chuck
part of the main unit.
䡬
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 166 mm, 160 mm, and 110 mm overall
length.)
䡬
Dump particles after every two or three holes when
drilling.
䡬
Please replace the drill bit after removing dust
collector (B).
6. Selecting the driver bit
Screw heads or bits will be damaged unless a bit
appropriate for the screw diameter is employed to
drive in the screws.
7. Confirm the direction of bit rotation (Fig. 5)
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the push button.
The L-side of the push button is pushed to turn the bit
counterclockwise.

HOW TO USE
CAUTION
To prevent accidents, make sure to turn the switch
off and disconnect the plug from the receptacle when
the drill pits 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.
2. Ro 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).
Fig. 6
(1) Mount the drill bit.
(2) Pull the trigger switch after applying the drill bit tip to
the drilling position (Fig. 7).
Fig. 7
(3) Pushing the rotary hammer forcibly is not necessary
at all. Pushing slightly so that drill dust comes out
gradually is sufficient.
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 pussing the push button and turning the change
lever to the mark (
Fig. 8).
