INSTALLING BITS
See Figure 6 - 7.
Lock the switch trigger by placing the direction of
rotation selector in the center position.
Open or close the chuck jaws to a point where the
opening is slightly larger than the bit size you intend to
use. Also, raise the front of the drill slightly to keep the
bit from falling out of the chuck jaws.
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 personal injury
or damage to the chuck.
Tighten the chuck jaws on the drill bit.
NOTE:
Rotate the chuck body in the direction of the arrow
marked LOCK to close the chuck jaws. Do not use a
wrench to tighten or loosen the chuck jaws.
REMOVING BITS
See Figure 6.
Lock the switch trigger by placing the direction of
rotation selector in the center position.
Open the chuck jaws.
NOTE:
Rotate the chuck body in the direction of the arrow
marked UNLOCK to open the chuck jaws. Do not use a
wrench to tighten or loosen the chuck jaws.
Remove the drill bit.
TWO-SPEED GEAR SWITCH (HIGH-LOW)
See Figure 9.
A slide switch is located on top of the drill to select either
low (1) or high (2) speed. When using drill in the low (1)
speed range, speed will decrease and unit will have more
power and torque. When using drill in the high (2) speed
range, speed will increase and unit will have less power
and torque. Use low (1) speed for high power and torque
applications and high (2) speed for fast drilling or driving
applications.
ADJUSTABLE TORQUE CLUTCH
See Figure 8.
When using the drill-driver for various driving applications,
it becomes necessary to increase or decrease the torque
in order to help prevent the possibility of damaging screw
heads, threads, workpiece, and so on. In general, torque
intensity should correspond to the screw diameter. If the
torque is too high or the screws too small, the screws may
be damaged or broken.
The torque is adjusted by rotating the torque adjustment
ring. The torque is greater when the torque adjustment
ring is set on a higher setting. The torque is less when the
torque adjustment ring is set on a lower setting.
The proper setting depends on the type of material and the
size of screw you are using.
ADJUSTING TORQUE
Identify the 24 torque indicator settings located on the
front of the drill.
Rotate adjusting ring to the desired setting.

DRILLING
Check the direction of rotation selector for the correct
setting (forward or reverse).
Secure the material to be drilled in a vise or with
clamps to keep it from turning as the drill bit rotates.
Hold the drill firmly and place the bit at the point to
be drilled.
Depress the switch trigger to start the drill.
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.
WARNING
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.
When drilling hard, smooth surfaces, use a center
