OPERATING INSTRUCTIONS
Important:
Always be sure that the tool is switched off and
unplugged before installing or removing the side grip,
bit or other accessories.
Installing or removing drill bit (Fig. 1)
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far
as it will go. Hold the ring firmly and turn the sleeve
clockwise to tighten the chuck. To remove the bit, hold
the ring and turn the sleeve counterclockwise.
Switch action (Fig. 2)
CAUTION:
Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
''OFF'' position when released.
To start the tool, simply pull the trigger. Tool speed is
increased by increasing pressure on the trigger.
Release the trigger to stop.
For continuous operation, pull the trigger and then
push the lock lever upward. To stop the tool from the
locked position, pull the trigger fully, then release it.
Reversing switch action (Fig. 3)
CAUTION:
• Always check the direction of rotation before opera-
tion.
• Use the reversing switch only after the tool comes to
a complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
This tool has a reversing switch to change the direc-
ENB001-1
tion of rotation. Move the reversing switch lever to the
position (A side) for clockwise rotation or the
position (B side) for counterclockwise rotation.
Side grip (auxiliary handle) (Fig. 4)
Always use the side grip to ensure operating safety.
Install the side grip so that the teeth on the grip fit in
between the protrusions on the tool barrel. Then
tighten the grip by turning clockwise at the desired
position. It may be swung 360° so as to be secured at
any position.
Depth gauge (optional accessory) (Fig. 5)
The depth gauge is convenient for drilling holes of
uniform depth. Loosen the side grip and insert the
depth gauge into the hole in the side grip. Adjust the
depth gauge to the desired depth and tighten the side
grip.
NOTE:
The depth gauge cannot be used at the position
where the depth gauge strikes against the gear
housing.
Drilling operation
• Drilling in wood
When drilling in wood, the best results are obtained
with wood drills equipped with a guide screw. The
guide screw makes drilling easier by pulling the bit
into the workpiece.
• Drilling in metal
To prevent the bit from slipping when starting a hole,
make an indentation with a center-punch and ham-
mer at the point to be drilled. Place the point of the
bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The
exceptions are iron and brass which should be drilled
dry.
