unplugged before adjusting or checking function on
the tool.

CAUTION:
• Before plugging in the tool, always check to see
that the switch trigger actuates properly and returns
to the "OFF" position when released.
• Switch can be locked in "ON" position for ease of
operator comfort during extended use. Apply cau-
tion when locking tool in "ON" position and maintain
firm grasp on tool.
To start the tool, simply pull the switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
For continuous operation, pull the switch trigger and then
push in the lock button.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
Reversing switch action
1
This tool has a reversing switch to change the direction of
rotation. Move the reversing switch lever to the "FWD"
position for clockwise rotation or the "REV" position for
counterclockwise rotation.
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 rota-
tion before the tool stops may damage the tool.

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing drill bit
To install the bit, place it in the chuck as far as it will go.
Tighten the chuck by hand. Place the chuck key in each
of the three holes and tighten clockwise. Be sure to
tighten all three chuck holes evenly.
To remove the bit, turn the chuck key counterclockwise in
just one hole, then loosen the chuck by hand.

OPERATION

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 hammer 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 excep-
tions are iron and brass which should be drilled dry.
CAUTION:
• Pressing excessively on the tool will not speed up
the drilling. In fact, this excessive pressure will only
serve to damage the tip of your bit, decrease the
tool performance and shorten the service life of the
tool.
• There is a tremendous twisting force exerted on the
tool/bit at the time of hole breakthrough. Hold the
tool firmly and exert care when the bit begins to
break through the workpiece.
• A stuck bit can be removed simply by setting the
reversing switch to reverse rotation in order to back
out. However, the tool may back out abruptly if you
do not hold it firmly.
• Always secure small workpieces in a vise or similar
hold-down device.
