Drilling (Fig.D)
NOTICE: If drilling thin material, use a wood “back-
up” block to prevent damage to thematerial.
1. Select the desired speed/torque range using the gear
shifter
4
to match the speed and torque to the planned
operation. Turn the collar
3
to the drillsymbol.
2. Use sharp drill bits only. For MASONRY, such as brick,
cement, cinder block, etc., use carbide-tipped bits rated
for percussiondrilling.
3. 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 thebit.
4. 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 batterypack.
WARNING: Drill may stall if overloaded causing a
sudden twist. Always expect the stall. Grip the drill
firmly to control the twisting action and avoidinjury.
5. 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 depress TRIGGER
ON AND OFF IN AN ATTEMPT TO START A STALLED
DRILL — THIS CAN DAMAGE THEDRILL.
6. To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last fractional part of thehole.
7. Keep the motor running when pulling the bit back out
of a drilled hole. This will help preventjamming.
Hammerdrilling (Fig.E)
1. Select the desired speed/torque range using the gear
shifter
4
to match the speed and torque to the planned
operation. Turn the collar
3
to the hammerdrillsymbol.
iMPORTAnT: Use carbide-tipped or masonry bits rated
for percussion drillingonly.
2. 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 a lower drillingrate.
3. 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
drillingspeed.
4. When drilling deep holes, if the hammer speed starts to
drop off, pull the bit partially out of the hole with tool
still running to help clear debris from thehole.
nOTE: A smooth, even flow of dust from the hole indicates
proper drillingrate.
