OPERATION
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 4, page 12.
The direction of bit rotation is reversible and is controlled
by a selector located above the switch trigger. With the drill
held in normal operating position, the direction of rotation
selector should be positioned to the left of the switch trigger
for forward drilling. The drilling direction is reversed when
the selector is to the right of the switch trigger.
Setting the direction of rotation selector in the OFF (center
lock) position helps reduce the possibility of accidental start-
ing when not in use.
CAUTION:
To prevent gear damage, always allow the chuck
to come to a complete stop before changing the
direction of rotation.
To stop the drill, release the switch trigger and allow the
chuck to come to a complete stop.
NOTE: The drill will not run unless the direction of rotation
selector is pushed fully to the left or right.
Avoid running the drill at low speeds for extended periods
of time. Running at low speeds under constant usage may
cause the drill to become overheated. If this occurs, cool the
drill by running it without a load and at full speed.
KEYLESS CHUCK
See Figure 5, page 12.
The drill has a keyless chuck to tighten or release drill bits
in the chuck jaws. The arrows on the chuck indicate which
direction to rotate the chuck body in order to LOCK or
UNLOCK the drill bit.
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.
TWO-SPEED GEAR TRAIN
See Figure 6, page 12.
The drill has a two-speed gear train designed for drilling or
driving at LO (1) or HI (2) speeds. A slide switch is located on
top of the drill to select either LO (1) or HI (2) speed. When
using drill in the LO (1) speed range, speed will decrease
and unit will have more torque. When using drill in the HI
(2) speed range, speed will increase and unit will have less
torque. Use LO (1) speed for high torque applications and
HI (2) speed for fast drilling or driving applications.
NOTE: If you have difficulty changing from one gear range
to the other, turn the chuck by hand until the gears engage.
CAUTION:
Never change gears while the tool is running.
Failure to obey this caution could result in serious
damage to the drill.
ADJUSTABLE TORQUE CLUTCH
This product is equipped with an adjustable torque clutch
for driving different types of screws into different materials.
The proper setting depends on the type of material and the
size of screw you are using.
ADJUSTING TORQUE
See Figure 6, page 12.
There are eighteen torque indicator settings located on the
front of the drill.
 Rotate the torque adjustment ring to the desired setting.
• 1 - 3 For driving small screws
• 4 - 7 For driving screws into soft material
• 8 - 11 For driving screws into soft and hard
materials
• 12 - 14 For driving screws into hard wood
• 15 - 18 For driving large screws
INSTALLING/REMOVING BITS
See Figures 5 and 7, page 12.
To install:
 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 open-
ing 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, as shown in figure 7.
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 securely on the bit.
NOTE: Rotate the chuck body in the direction of the ar-
row marked LOCK to close the chuck jaws. Do not use
a wrench to tighten or loosen the chuck jaws.
To remove:
 Lock the switch trigger by placing the direction of rotation
selector in the center position.
