INSTALLING/REMOVING BITS
See Figures 5 - 6, page 9.
The arrows on the keyless chuck indicate which direction
to rotate the chuck body to tighten or release the drill bit.
Do not use a wrench to tighten or loosen the chuck jaws.
 To install bits, lock the switch trigger.
 Open or close the chuck jaws until the opening is slightly
larger than the bit size you intend to use.
 Raise the front of the drill slightly and insert the drill bit.
WARNING:
Make sure to insert the drill bit straight into the chuck
jaws. Do not insert the drill bit into the chuck jaws at an
angle, then tighten. This could cause the drill bit to be
thrown from the drill, resulting in possible serious per-
sonal injury or damage to the chuck.
 Grasp and hold the collar of the chuck with one hand.
With your other hand, rotate the chuck body to close and
tighten the chuck jaws.
WARNING:
Do not hold the chuck body with one hand and use the
power of the drill to tighten the chuck jaws on the drill
bit. The chuck body could slip in your hand, or your
hand could slip and come in contact with the rotating
drill bit. This could cause an accident resulting in serious
personal injury.
 To remove bits, lock the switch trigger and open the
chuck jaws.
 The bit provided with the drill can be placed in the storage
area, located on the base of the drill.
DRILLING/DRIVING SCREWS
See Figure 7, page 9.
A level is located on top of the motor housing to help keep
the drill bit level during use.
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Use LO (1) speed for high torque applications and
HI (2) speed for fast drilling or driving applications. Refer
to Two-Speed Gear Train and Adjusting Torque.
 Secure the workpiece in a vise or with clamps to keep it
from turning as the bit rotates.
 Hold the drill firmly and place the bit at the point to be
drilled, or where the screw is to be driven.

OPERATION
 Depress the switch trigger to start the drill.
 Move the bit into the workpiece, applying only enough
 With hard, smooth surfaces, use a center punch to mark
 If the bit jams in the workpiece or if the drill stalls, stop
NOTE: This drill has an electric brake. When the switch trig-
ger is released, the chuck stops turning. 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.

WARNING
:
Do not drive a screw where there is likely to be hidden
wiring behind the surface. Contact with a "live" wire will
make exposed metal parts of the tool "live" and possibly
shock the operator. If you must drive a screw where hid-
den wire may be present, always hold tool by insulated
gripping surfaces (handle) when performing the operation
to prevent a shock to the operator.
pressure to keep the bit cutting or driving the screw. Do not force the drill or apply side pressure to elongate a
hole. Let the tool do the work.
WARNING
:
When drilling, be prepared for binding at bit breakthrough.
When these situations occur, drill 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 can result in possible
serious injury.
the desired hole location. This will prevent the bit from
slipping off-center as the hole is started.
the tool immediately. Remove the bit from the workpiece
and determine the reason for jamming.
