SWITCH TRIGGER
See Figure 3, page 13.
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 13.
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 4, page 13.
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 (tighten)
or UNLOCK (release) the drill bit.
WARNING:
Do not hold the chuck 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.
OPERATION
TWO-SPEED GEAR TRAIN (HI-LO)
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.
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 13.
There are twenty-four torque indicator settings located on
the front of the drill.
 Rotate the adjusting ring to the desired setting.
• 1 - 4
• 5 - 8
• 9 - 12 For driving screws into soft and hard
• 13 - 16 For driving screws into hard wood
• 17 - 20 For driving large screws
• 21-
MAG TRAY™ (SCREW HOLDER)
See Figure 7, page 13.
The magnetic tray conveniently stores screws or other small
parts.
INSTALLING/REMOVING BITS
See Figures 8 - 9, page 13.
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 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.
