Drill Operation (fi g. 5, 7)
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
firmly. If drilling thin material, use a wood
"back-up" block to prevent damage to
the material.
1. Select the desired speed/torque range using the
gear shifter (d) to match the speed and torque
to the planned operation.
2. 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.
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 the bit.
4. Hold tool firmly with both hands to control the
twisting action of the drill.
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.
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 CLICK TRIGGER ON AND
OFF 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.
7. Keep the motor running when pulling the bit
back out of a drilled hole. This will help prevent
jamming.
8. 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.
Screwdriver Operation (fi g. 5, 7)
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 (c) 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.

MAINTENANCE

Your D WALT power tool has been designed to
E
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper tool care and regular cleaning.
