OPERATION
AS A DRILL (Fig. 15)
Turn and set the torque clutch collar to the drilling position symbol'&_1. Install and tighten the
desired drill bit into the chuck.
1. Install the battery pack into the drill / driver.
2. Push the forward/reverse selector switch with power lock-off to the forward position.
3. For drilling in WOOD, use twist drill bits, spade bits and auger bits.
4. For drilling in METAL, use high speed twist drill bits. Use a cutting lubricant when drilling
in metals. The exceptions are cast iron and brass, which should be drilled dry.
5. For drilling in MASONRY, use carbide tipped bits or masonry bits. A smooth, even flow of
dust indicates the proper drilling speed.
6. Always apply pressure in a straight line with Fig. 15
the bit. If necessary, use the bubble levels
to drill straight into the workpiece. Use enough
pressure to keep the bit biting, but do not
push hard enough to stall the motor or
deflect the bit.
7. Hold drill/driver firmly to control the twisting
action of the drill/driver.
8. Move the drill bit into the workpiece, applying
only enough pressure to keep the bit cutting.
Do not force the drill or apply side pressure
to elongate a hole. Let the tool do the work.
9. When drilling hard, smooth surfaces, use a
center punch to mark the desired hole
location. This will prevent the drill bit from
slipping off-center as the hole is started.
10. If the drill/driver stalls, or the bit jams in the
workpiece, it is usually because the
drill/driver is being overloaded. RELEASE
TRIGGER SWITCH IMMEDIATELY and
remove bit from workpiece. Determine cause
of stalling. DO NOT PRESS TRIGGER OFF AND ON IN AN ATTEMPT TO START
A STALLED DRILL/DRIVER -THIS COULD DAMAGE THE DRILL/DRIVER.
11. Keep the motor running when pulling the bit back out of a drillled hole. This will help
prevent jamming.
z_ WARNiNG:Be prepared for binding at bit breakthrough. When these situations
occur, drill / driver has a tendency to grab and kick opposite to the direction of rotation
and could cause loss of control when breaking through material. If not prepared, this
loss of control could result in possible serious injury.
NOTE: This drill / driver has an electric brake. When the trigger switch is released, the
chuck stops turning instantly. When the brake is functioning properly, sparks will be
visible through the vent slots on the housing.This is normal and is the action of the brake.

OPERATION AS A SCREWDRIVER
(Fig. 16) Fig. 16
Turn and set the torque clutch collar to the
desired torque setting, 1 through 23. Install _(_r_
and tighten the desired fastener accessory __ _1_
bit into the chuck.
1. Install the battery pack into the drill / driver.
2. Push the forward / reverse selector switch
to the forward position.
3. Set the collar to the lowest setting, "1"
4. Drive and tighten the first screw
5. If the clutch ratchets before the screw is
tightened, increase the torque setting
and continue to tighten the screw.
6. Repeat this process until you reach a torque setting that drives and tightens the screw
without the clutch ratcheting.
7. Use that torque setting to drive and tighten the remaining screws.
8. To remove fasteners, push forward / reverse selector switch to the reverse position.
z_ WARNING:
When servicing, use only identical Craftsman replacement parts.
Use of any other part may create a hazard or cause product damage.
/!k WARNING:
ALWAYS wear safety goggles or safety glasses with side
shields when using compressed air to clean tools, if the operation is dusty,
also wear a dust mask.
Z_ WARNING:
To avoid serious personal injury, always remove the battery
pack from the tool when cleaning or performing any maintenance.
