WARNING: Do not attempt to tighten drill bits (or
any other accessory) by gripping the front part of the
chuck and turning the tool on. Damage to the chuck
and personal injury may result. Always lock off trigger
switch when changing acces sories.
Be sure to tighten chuck with one hand on the chuck sleeve
and one hand holding the tool for maximum tightness.
Chuck Removal (Fig. G)
Turn the adjustment collar
4
to the “drill” position and
gear shifter
5
to position 1 (low speed). Tighten the chuck
around the shorter end of a hex key (not supplied) of 1/4"
(6.4mm) 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 in
FigureF. 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. H)
Screw the chuck on by hand as far as it will go and
insert screw (left-hand 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.
Drill Operation (Fig. A)
WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can cause injury.
WARNING: TO REDUCE THE RISK OF PERSONAL
INJURY, ALWAYS ensure workpiece is anchored or
clamped firmly. If drilling thin material, use a wood
“back-up” block to prevent damage to the material.
Turn the collar
4
to the drill bit symbol for drilling. Select
the desired speed/torque range using the gear shifter
5
to
match the speed and torque to the planned operation.
1. Use sharp drill bits only. For WOOD, use twist drill bits,
spade bits, or hole saws. For METAL, use high-speed
steel (HSS) twist drill bits or hole saws.
2. Always apply pressure in a straight line with the bit. Use
enough pressure to keep drill biting, but do not push
hard enough to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting
action of the drill.
WARNING: The drill may stall if overloaded causing
a sudden twist. Always expect the stall. Grip the drill
firmly with both hands to control the twisting action
and avoid injury.
4. IF DRILL STALLS, it is usually because it is being
overloaded or improperly used. RELEASE TRIGGER
IMMEDIATELY, remove drill bit from work, and
determine cause of stalling. DO NOT CLICK TRIGGER ON
AND OFF IN AN ATTEMPT TO START A STALLED DRILL
— THIS CAN DAMAGE THE DRILL.
5. To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last fractional part of the hole.
6. Keep the motor running when pulling the bit back out
of a drilled hole. This will help prevent jamming.
7. With variable speed drills there is no need to center
punch the point to be drilled. Use a slow speed to start
the hole and accelerate by squeezing the trigger harder
when the hole is deep enough to drill without the bit
skipping out.
Operation as a Screwdriver (Fig. A)
Select the desired speed/torque range using the dual range
gear shifter
5
on the top of tool to match the speed and
torque to the planned operation.
Insert the desired fastener accessory into the chuck
6
as
you would any drill bit. Make a few practice runs in scrap or
unseen areas to determine the proper position of the clutch
collar
4
.
Hammerdrill Operation (Fig. A)
1. Turn the collar
4
to the hammerdrill symbol.
2. Select the high speed setting by sliding the selector
back (away from the chuck).
IMPORTANT: Use carbide-tipped or masonry bits only.
3. Drill with just enough force on the hammer to keep
it from bouncing excessively or “rising” off the bit.
Too much force will cause slower drilling speeds,
overheating and lower drilling rate.
4. Drill straight, keeping the bit at a right angle to the work.
Do not exert side pressure on the bit when drillling as
this will cause clogging of the bit flutes and a slower
drilling speed.
5. When drilling deep holes, if the hammer speed starts to
drop off, pull the bit partially out of the hole with tool
stil running to help clear debris from the hole.
NOTE: A smooth, even flow of dust from the hole indicates
proper drilling rate.
