suited to the operation and then securely
tighten the side handle grip.
To attach a depth gauge on the side
handle, insert the gauge into the

how to use
1. Intended use.
CAUTION
The power tool is designed for domestic
use and is not intended for industrial
purposes. In case of using the power tool
for industrial purposes, the manufacturer
disclaims the product warranty liabilities.
2. Pressing force of the drill.
You cannot drill holes more quickly even
if you press the drill with a stronger force
than necessary. It not only damages tip
of drill bit and decreases the efficiency of
operation, but also shortens the life of the
drill tip.
3. When a thick drill bit is used.
Your arm is subjected to larger reaction
force when a thicker drill bit is used. Be
careful not to be moved by the reaction
force. For this, establish a foothold;
hold the unit tightly with both hands
perpendicularly to the material being
drilled.
4. In case of penetrating holes.
Drill bits can be broken when the
material being drilled is penetrated. It
is important to decrease pressing force
just before penetrating. In continuous
operation, conduct no-load operation for
five seconds after completing a drilling
job.
5. Speed control dial.
Speed is adjusted by turning the speed
control dial, which is located on the On/
Off switch.
6. Reverse function.
The drill is equipped with direction
switch function.
For turning the bit clockwise switch the
rotation direction switch in the left end
position.
For turning the bit counterclockwise
switch the rotation direction switch into
the right end position.
7. Precautions on drilling.
The bit can overheat while drilling. Do
not cool the bit in water or oil.
8. Precautions right after using.
Do not put the drill with rotating bit in
place, where there is dust and chips, as
the drilling mechanism can suck them in.
maintenance and inspection
1. Inspecting the drill bits.
Since use of an abraded drill bits
will cause motor malfunctioning and
degraded efficiency, replace the drill bits
with a new one or resharpening without
delay when abrasion is noted.
2. Inspecting the mounting screws.
Regularly inspect all mounting screws
and ensure that they are properly
tightened. Should any of the screws
be loose, retighten them immediately.
Failure to do so could result in serious
hazard.
3. Maintenance of the motor.
The motor unit winding is the very
“heart” of the power tool. Exercise due
care to ensure the winding does not
become damaged and/or wet with oil or
water.
4. Inspecting the carbon brushes.
