ASSEMBLY AND OPERATION
APPLICATIONS
Boring holes in metal, wood and plastic.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms to the power source requirements
specified on the product nameplate.
2. Power switch
Ensure that the switch is in the OFF position. If the plug is connected to a receptacle while
the switch is in the ON position, the power tool will start operating immediately and can
cause serious injury.
3. Extension cord
When the work area is far away from the power source, use an extension cord of sufficient
thickness and rated capacity. The extension cord should be kept as short as practicable.
WARNING:
4. Check the receptacle
If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact
a licensed electrician to make appropriate repairs.
If such a fautly receptacle is used, it may cause overheating, resulting in a serious hazard.
5. Confirming condition of the environment:
Confirm that the work site is placed under appropriate conditions conforming to
prescribed precautions.
6. Selecting the appropriate drill bit:
When boring metal or plastic
Use an ordinary metalworking drill bit.
When boring wood
Use an ordinary woodworking drill bit.
However, when drilling 1/4" (6.5 mm) or smaller holes, use a metalworking drill bit.
7. Mounting and dismounting of the bit.
For Drill chuck with chuck wrench (Fig. 2)
Fit the drill bit into the chuck and use the chuck wrench to secure it, tightening the chuck
by each of the three holes in turn.
For keyless chuck (Fig. 3, 4)
(1) Mounting the bit
Turn the lock collar in the direction "UNLOCK" and open the chuck. After inserting the drill
bit into the chuck as far it will go, turn the lock collar in the "LOCK" direction. Grip the
retaining ring and close the chuck by turning the sleeve clockwise as viewed from the
front.
