Standard accessories are subject to change without notice.
APPLICATIONS
Drilling holes on various metal, lumber and plastics.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Grounding
This tool should be grounded while in use to protect
the operator from electric shock. The tool is equipped
with a three conductor cord and grounding type
plug to fit the proper grounding type receptacle. The
green (or green and yellow) conductor in the cord
is the grounding wire. Never connect the green (or
green and yellow) wire to a live terminal.
3. 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.
4. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
CAUTION
Damaged cord must be replaced or repaired.
5. Confirming condition of the environment
Confirm that the work site is placed under
appropriate conditions conforming to prescribed
precautions.
6. How to select drill bits
(1) When drilling holes in metals or plastics
U s e o r d i n a r y m e t a l w o r k i n g d r i l l b i t s ,
applicable drill sizes range from min. 1.2 mm
to max. 13 mm.

5. Never let the drill alone in the rotating conditions.
6. Avoid letting the revolution down largely by means
of pressing it by force.
7. Take care of downward direction in the high position.
8. Before drilling into a wall, floor or ceiling, thoroughly
confirm that no items such as electric cables or
conduits are buried inside.

(2) When drilling holes in lumber
Use woodworking drill bits of 30 mm diam.
or below. For small holes of 6.5 mm diam.
or below, use metalworking drill bits.
7. Mounting drill bits
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 holes.
8. Confirm the power receptacle
If the power receptacle only loosely accepts the
plug, the receptacle must be repaired. Contact the
nearest electric store for repair service. If such a
faulty receptacle is used, it may cause overheating,
resulting in a serious hazard.
HOW TO USE THE DRILL
1. Pressing force of drill
You cannot 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 efficiency of operation, but also shortens the
life of the drill.
2. In case of penetrating holes
It is subject to break the drill bits when penetrating.
It is important to decrease pressing force when
penetrating.
3. Switch operation
Pulling the trigger and pushing 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.
4. Regarding the drill chuck
The drill chuck is secured to the spindle with a
taper. Should the drill chuck be accidentally detached
from the spindle, deposited on the chuck taper
section and the spindle chuck mount, tap the side
plane of the chuck after retracting its three claws,
and reattach it to the spindle. Carefully handle the
taper section so that its surface does not become
scarred.
