To select the high speed, low torque setting, turn the tool
off and permit to stop. Slide the gear selector back (away
from chuck).
NOTE: Do not change gears when the tool is running. If
you are having trouble changing gears, make sure that
the dual range gear selector is either completely pushed
forward or completely pushed back.
Worklight (fi g. 1)
There is a worklight (e) located just above the trigger
switch (a). The worklight will be activated when the
trigger switch is squeezed.
NOTE: The worklight is for lighting the immediate work
surface and is not intended to be used as a fl ashlight.
Keyless Single Sleeve Chuck (fi g. 1)
Your tool features a keyless chuck (f) with one rotating
sleeve for one-handed operation of the chuck. To insert
a drill bit or other accessory, follow these steps.
1. Lock the trigger in the OFF position as previously
described.
2. Grasp the black sleeve of the chuck with one hand
and use the other hand to secure the tool. Rotate
the sleeve counterclockwise far enough to accept
the desired accessory.
3. Insert the accessory about 19 mm into the chuck
and tighten securely by rotating the chuck sleeve
clockwise with one hand while holding the tool with
the other. Your tool is equipped with an automatic
spindle lock mechanism. This allows you to open
and close the chuck with one hand.
To release the accessory, repeat step 2 above.
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.
Drill Operation (fi g. 4)
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.
WARNING: To reduce the risk of personal
injury, ALWAYS ensure workpiece is

anchored or clamped fi rmly. If drilling thin
material, use a wood "back-up" block to
prevent damage to the material.
Use sharp drill bits only. For WOOD, use the low
speed setting and twist drill bits, spade bits, power
auger bits, or hole saws. For METAL, use the low
speed setting and steel twist drill bits or hole saws.
For MASONRY, such as brick, cement, cinder block,
etc., use carbide-tipped bits rated for percussion
drilling. Use low speed for bits greater than 10 mm.
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 defl ect the bit.
Hold tool fi rmly with both hands to control the twisting
action of the drill. If model is not equipped with side
handle, grip drill with one hand on the handle and
one hand on the battery pack.
CAUTION: Drill may stall if overloaded
causing a sudden twist. Always expect
the stall. Grip the drill fi rmly to control the
twisting action and avoid injury.
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.
To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last fractional part of the hole.
Keep the motor running when pulling the bit back out
of a drilled hole. This will help prevent jamming.
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.
Turn the collar (c) to the hammerdrill symbol.
Select the high speed setting by sliding the selector
back (away from the chuck).
IMPORTANT: Use carbide-tipped or masonry bits only.
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.
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 fl utes
and a slower drilling speed.
