English
Dump particles after every two or three holes when drilling.
Please replace the drill bit after removing dust collector (B).
8. Selecting the driver bit
Screw heads or bits will be damaged should an inappropriate bit for the screw diameter
be employed to drive in the screws.
9. 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. To turn
the switch OFF, release the trigger switch to
its original position.
2. Rotation + Striking
This rotary hammer can be set to rotation and
striking mode by pressing the push button and
turning the change lever to 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 just sufficient.
CAUTION:
When the drill bit touches an iron reinforcing rod, the bit will stop immediately and
the rotary hammer will react to revolve. Therefore please grip the side handle and
handle tightly as shown in Fig. 7.
