OPERATION

KEYLESS CHUCK

See Figure 3.
Your new drill has a keyless chuck. As the name implies, you

can hand tighten or release drill bit 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 shown in figure

3 indicate which direction to rotate the chuck body in order
to

GRIP (tighten) or RELEASE (unlock) the drill bit.

WARNING:

Do not hold the chuck body with one hand and use

the power of the drill to tighten chuck jaws on drill

bit. The chuck body could slip in your hand or your

hand could slip and come in contact with a rotating

drill bit. This could cause an accident resulting in
serious personal injury.

REVERSIBLE

See Figure 4.
Your electric drill has the feature of being reversible. The direc-

tion of chuck rotation is controlled by a lever located above

the switch trigger. With your drill held in normal operating

position, the direction of rotation lever should be positioned to

the left of the switch for drilling. The drill direction is reversed

when the lever is to the right of the switch.

WARNING:

Your drill should never be connected to power supply

when you are assembling parts, making adjustments,

installing or removing drill bits, cleaning, or when not

in use. Disconnecting your drill will prevent accidental

starting that could cause serious personal injury.

The design of the switch will not permit changing the direction

of rotation while the drill is running. Release the switch trigger

and allow the drill to stop before changing its direction
NOTE: Your drill will not run unless the switch lever is pushed
fully to the left or right.

VARIABLE SPEED

See Figure 5.
Your drill has a variable speed switch designed to allow

operator control of speed and torque limits. The speed

and torque of your drill can be increased by depressing the

switch trigger.
NOTE: Depress switch trigger all the way for maximum speed

and torque of your drill. Depress switch trigger only part of

the way for less speed and torque.
Avoid running your drill at low speeds for extended periods

of time. Running at low speeds under constant usage may

cause your drill to become overheated. If this occurs, cool

your drill by running it without a load and at full speed.
The following guidelines may be used in determining correct

speed for various applications:
n

Low speed is ideal when minimum speed and power is re-

quired. For example, starting holes without center punching,

driving screws, mixing paint, and drilling in ceramics.

TO INCREASE SPEED,

PULL SWITCH TRIGGER

Medium speed is suitable for drilling hard metals, plastics,
and laminates.

High speed produces best results when maximum power
is required. For example, drilling in wood; soft metals such
as aluminum, brass, and copper, and when using driving
accessories.
