PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specifi ed on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If
the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, inviting serious accident.
3. Extension cord
When the work area is removed from the power source,
use an extension cord of suffi cient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. Confi rm the direction of bit rotation (Fig. 1)
The bit rotates clockwise (viewed from the top
side) by pushing the R-side of the reversing switch
lever. The L-side of the lever is pushed to turn the bit
counterclockwise.
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.
5. Mounting drill bits (Fig. 2)
Tighten drill bits with the chuck wrench. There are three
holes in which the chuck wrench should be inserted.
Tighten them equally in turn at three holes, without
tightening them only at one hole. The drill bit can be
removed in the opposite method as mentioned above.

6. How to select drill bits
(1) When drilling holes in metals or plasstics:
Use ordinary metalworking drill bits, applicable drill
sizes range from min. 1.5 mm to drill chuck capacity.
(2) When drilling holes in wood:
Use woodworking drill bits. For small holes of 6.5 mm
diam. or below, use metalworking drill bits.
7. Fixing the side handle
Screw the side handle into the gear cover.
HOW TO USE
1. Switching instruction
(1) Turning the switch on
Slide the switch lever on the main body backward
as illustrated in Fig. 3. When you slide it backward
completely, the switch gets turned on and locked in that
condition.
(2) Turning the switch off
Press the round convex on the surface of the switch
lever as illustrated in Fig. 4. Then, the lock comes off ,
the switch lever returns forward on the main body by the
spring's force, and the switch gets turned off .
CAUTION
Check and make sure positively that the switch is
off before inserting the plug into the power outlet.
Otherwise, a sudden start of the tool defi nitely results
an accident.
2. Pressing force of drill
You can not get holes quickly even if pressing it by
strong force more than necessary.
It not only damages the tip of drill bits and decreases
the effi ciency of operation, but also shortens the life of
the drill.
3. When drilling completely through the material
When the drill bit bores completely through the material,
careless handling often results in a broken drill bit
or damage to the drill body itself due to the sudden
movement of the drill. Always be alert and ready to
release pushing force and hold the drill body securely
with both hands when drilling through the material.
