OPERATION

DIRECTION OF ROTATION SELECTOR

(FORWARD/REVERSE/CENTER LOCK)

See Figure 3.

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 switch trigger 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.

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.

INSTALLING BITS

See Figures 4 - 5.

■

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, as shown
in figure 9. 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

arrow marked

LOCK

to close the chuck jaws. Do not

use a wrench to tighten or loosen the chuck jaws.
