OPERATION
TO INSTALL/REMOVE BATTERY PACK
See Figure 2, page 12.
To install the battery pack:
 Lock the switch trigger on the drill by placing the direc-
tion of rotation (forward/reverse/center lock) selector in
center position.
 Align raised rib on battery pack with the groove inside
the tool.
 Make sure the latches on each side of the battery pack
snap in place and battery pack is secured before begin-
ning operation.
To remove the battery pack:
 Lock the switch trigger by placing the direction of rotation
selector in center position.
 Depress the latches on the sides of the battery pack.
The battery pack will disconnect in the direction to be
removed.
WARNING:
Battery tools are always in operating condition.
Therefore, switch should always be locked when
not in use or carrying at your side.
SWITCH TRIGGER
See Figure 3, page 12.
To turn the drill ON, depress the switch trigger. To turn it
OFF, release the switch trigger.
VARIABLE SPEED
The variable speed switch trigger delivers higher speed with
increased trigger pressure and lower speed with decreased
trigger pressure.
NOTE: You might hear a whistling or ringing noise from the
switch during use. Do not be concerned; this is a normal
part of the switch function.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 3, 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
starting 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 4, page 12.
The drill has a keyless chuck to tighten or release drill bits
in the chuck jaws. Grasp and hold the collar of the chuck
with one hand. Rotate the chuck body with your other hand.
The arrows on the chuck indicate which direction to rotate
the chuck body in order to LOCK (tighten) or UNLOCK
(release) the drill bit.
NOTE: When the chuck is fully tightened, it will make a
clicking sound.
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 5, page 13.
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 power and torque. When using drill
in the HI (2) speed range, speed will increase and unit will
have less power and torque. Use LO (1) speed for high power
and 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.
