Installing dust collector (B)
When using dust collector (B), insert dust collector
(B) from the tip of the bit by aligning it to the groove
on the grip (Fig. 5)
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
dust cup on the concrete surface. (When using dust
collector (B) attached to a drill bit that has more
than 7-15/32" (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 6-17/32" (166
mm), 6-19/64" (160 mm) and 4-21/64" (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).
8. 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.

9. Confirm the direction of bit rotation (Fig. 6)
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:
䡬
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
䡬
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. To turn the switch OFF, 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.
䡬
Pulling the trigger and pushing the stopper, it keeps
the switched-on condition which is convenient for
continuous running. When switching off, the
stopper can be disconnected by pulling the trigger
again. The switch stopper is unusable during
reverse.
2. Ro Hammering
This rotary hammer can be set to rotation and
hammering mode by turning the change lever to
the
mark (Fig. 7).
