OPERATION

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 i.

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.

TWO-SPEED GEAR TRAIN (HI-LO)

See Figure 5, page i.

The drill has a two-speed gear train designed for drilling or
driving at

LO (1)

HI (2)

speeds. A slide switch is located on

top of the drill to select either

LO (1)

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.
