9. High-speed/Low-speed changeover
To change speed, rotate the gear shift
dial as indicated by the arrow in Fig. 7.
The numeral "1" engraved on the drill
body denotes low speed, the numeral
"2" denotes high speed.
10. Confirm the direction of bit
rotation
The bit rotates clockwise (viewed from
the rear side) by pushing the R-side of
the reversing switch lever.
The L-side of the lever is pushed to
turn the bit counterclockwise. (Fig.
8)
CAUTION
Never change the direction of bit rotation
while operating. Turn the power switch
OFF before changing the direction of bit
rotation: otherwise, burning of the motor
will result.
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. Operation of switch
The drill speed can be adjusted from O through full speed by regulating the triger-
squeezing force. The more the trigger is squeezed, the faster the drill rotates. When the
trigger is squeezed fully, the speed is the maximum.
Pulling the trigger and pushig 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.
2. Pressing force of the drill
You can not get holes quickly even if pressing it by stronger more than necessary. It not
only damages the tip of drill bits and decreases the efficiency of operation, but also
shortens the life of the drill.
3. In case of penetrating holes
It is subject to break the drill bits when penetrating. It is important to decrease pressing
force when penetrating.
