OPERATING INSTRUCTIONS
6. Installing Bits (sold separately)
a. Unplug the drill from the power source.
b. Lock the trigger switch by placing the direction-of-
rotation selector (D) in the OFF (center) position.
c. Open the chuck (C) jaws by turning the sleeve (A)
in a counterclockwise direction until the opening is
slightly larger than the bit you intend to use. Raise
the front of the drill slightly to keep the bit from
falling out of the chuck (C) jaws.
d. Insert the drill bit into the chuck.
e. Tighten the sleeve by hand.
f. Place the chuck key (F) in one of the three chuck
key holes (B) and tighten in clockwise direction.
Repeat with the remaining two chuck-key holes.
WARNING
It is important to tighten the chuck with all three
chuck-key holes to prevent slippage.
g. Remove the chuck key.
WARNING
Insert the drill bit straight into the chuck jaws.
Inserting the drill bit into the chuck jaws at an angle
and then tightening the chuck and using the drill
could cause the drill bit to be thrown from the drill,
resulting in possible serious personal injury or
damage to the chuck.
7. Removing Bits
a. Unplug the drill from the power source.
b. Lock the trigger switch (E) by placing the
direction-of-rotation selector (D) in the OFF
(center) position.
c. Place the chuck key (F) in one of the three
chuck-key holes (B) and loosen the chuck (C) by
turning in a counterclockwise direction.
d. Loosen the sleeve (A) by hand.
e. Remove the drill bit.
f. Remove the chuck key.

OPERATING INSTRUCTIONS
8. Drilling
a. Secure the material to be drilled in a vise or with
clamps to keep it from turning as the drill bit rotates.
b. Install the correct bit.
c. Verify that the direction-of-rotation selector (D) is
at the correct setting (forward).
d. Hold the drill firmly and place the bit at the point to
be drilled.
e. Press the trigger switch (E) to start the drill.
f. Move the drill bit into the workpiece, applying only
enough pressure to keep the bit cutting. Do not
force the drill or apply side pressure to elongate a
hole. Allow the tool to do the work.
g. When drilling hard, smooth surfaces, use a center
punch to mark the desired location of the hole.
This will prevent the drill bit from slipping off-
center as the hole is started.
h. When drilling metals, use light oil on the drill bit to keep it from overheating. The oil will prolong the
life of the bit and increase the drilling action.
i. If the bit jams in the workpiece or if the drill stalls, stop the tool immediately. Reverse the direction
of rotation and gently squeeze the trigger switch to remove the bit from the workpiece. Investigate
and correct the cause of jamming before you resume work.
9. Drilling in Wood
For maximum performance, use high-speed steel or brad-point bits for wood drilling.
a. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
b. Increase the speed as the drill bit enters the material.
c. When drilling holes all the way through the workpiece, place a block of wood behind the workpiece
to prevent ragged or splintered edges on the back side of the hole.
10. Drilling in Metal
For maximum performance, use high-speed steel bits for metal or steel drilling.
a. When drilling metals, use light oil on the drill bit to keep it from overheating. The oil will prolong the
life of the bit and increase the drilling action.
b. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
c. Maintain a speed and pressure that allows cutting without overheating the bit. Applying too much
pressure will:
– Overheat the drill
– Wear the bearings
– Bend or burn the bits
– Produce off-center or irregularly-shaped holes
