clamped firmly. If drilling thin material, use a wood “back-
up” block to prevent damage to thematerial.
1. Turn the collar
3
to the drillsymbol.
2. Select the desired speed/torque range using the gear shifter
to match the speed and torque to the plannedoperation.
3. For Wood, use twist bits, spade bits, power auger bits or
hole saws. For Metal, use high-speed steel twist drill bits
or hole saws. Use a cutting lubricant when drilling metals.
The exceptions are cast iron and brass which should be
drilleddry.
4. 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.
5. Hold tool firmly 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 firmly to control
the twisting action and avoidinjury.
6. 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.
7. To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the last
fractional part of thehole.
8. Keep the motor running when pulling the bit back out of a
drilled hole. This will help preventjamming.
9. 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.
Hammerdrill Operation (Fig. E)
1. Turn the collar
3
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.
Screwdriver Operation (Fig. F)
1. Select the desired speed/torque range using the dual
range gear selector to match the speed and torque of the
plannedoperation.
2. Turn the torque adjustment collar
3
to the desired position.
Lower numbers indicate lower torque settings; higher
numbers indicate higher torquesettings.
3. Insert the desired fastener accessory into the chuck as you
would any drillbit.
4. Make some practice runs in scrap or on unseen areas to
determine the proper position of the clutchcollar.
5. Always start with lower torque settings, then advance to
higher torque settings to avoid damage to the workpiece
orfastener.
