Chuck Removal (Fig. 7)
WARNING: Always wear ANSI Z87.1 eye protection (CAN/CSA
Z94.3) eye protection.
Turn the adjustment collar to the "drill" position and low speed gear
shifter to position 1. Tighten the chuck around the shorter end of
a hex key (not supplied) of 1/4" (6.4 mm) or greater size. Using a
wooden mallet or similar object, strike the longer end in the clockwise
direction, as shown. This will loosen the screw inside the chuck.
Open chuck jaws fully, insert screwdriver (or Torx tool if required) into
front of chuck between jaws to engage screw head. Remove screw
by turning clockwise (left-hand-thread). Place hex key in chuck and
tighten, as shown. Using a wooden mallet or similar object, strike key
sharply in the counterclockwise direction. This will loosen the chuck
so that it can be unscrewed by hand.

Chuck Installation (Fig. 8)
Screw the chuck on by hand as far as it will go and insert screw (LH
thread). Tighten screw securely. Tighten the chuck around the shorter
end of a 1/4" (6.4 mm) or larger hex key (not supplied) strike the
longer end in the clockwise direction with a wooden mallet, as shown.
Tighten the screw once again by turning in a counterclockwise
direction.
Operation as a Drill
Turn the collar to the drill bit symbol. Install and tighten the desired
drill bit in the chuck. Select the desired speed/torque range using the
dual range gear shifter to match the speed and torque to the planned
operation. Follow these instructions for best results when drilling.
DRILLING
1. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits,
power auger bits, or hole saws. For METAL, use high speed steel
twist drill bits or hole saws.
2. Be sure the material to be drilled is anchored or clamped firmly. If
drilling thin material, use a "back-up" block to prevent damage to
the material.
3. Always apply pressure in a straight line with the bit. Use enough
pressure to keep the drill bit biting, but do not push hard enough
to stall the motor or deflect the bit.
4. Hold tool firmly to control the twisting action of the drill.
5. IF DRILL STALLS, it is usually because it is being overloaded.
RELEASE TRIGGER IMMEDIATELY, remove drill bit from work,
and determine cause of stalling. DO NOT CLICK TRIGGER OFF
AND ON IN AN ATTEMPT TO START A STALLED DRILL – THIS
CAN DAMAGE THE DRILL.
6. To minimize stalling or breaking through the material, reduce
pressure on drill and ease the bit through the last fractional part
of the hole.
