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.
●
Dump particles after every two or three holes
when drilling.
●
Please replace the drill bit after removing dust
collector (B).
4. 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.
5. Confirm the direction of bit rotation (Fig. 9)
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. (See Fig. 9) (The
marks are provided on the body.)

These data are for the referential values. The number of
holes that can be drilled varies according to the sharpness
of the used bit or the conditions of the concrete being
drilled.
CAUTION:
When using this unit continuously, the unit may
overheat, leading to damage in the motor and
switch. Please leave it without using it for
approximately 15 minutes.
HOW TO USE
1. Switch operation
When the switch trigger is depressed, the tool
rotates. When the switch trigger is released, the tool
stops.
The rotational speed of the rotary hammer can be
controlled by varying the amount that the switch
trigger is pulled. Speed is low when the switch
trigger is pulled slightly and increases as the switch
trigger is pulled more.
When releasing the switch trigger, the brake will
be applied for immediate stopping.
2. Rotation + Hammering
Turn the change lever fully in the direction of the
" " mark to set "rotation + hammering". (Fig.
10)
