OPERATION

WARNING:
Do not allow familiarity with tools to make you
careless. Remember that a careless fraction of a
second is sufficient to inflict severe injury.
WARNING:
Always wear eye protection marked to comply with
ANSI Z87.1. Failure to do so could result in objects
being thrown into your eyes resulting in possible
serious injury.
APPLICATIONS
You may use this tool for the purposes listed below:
 Drilling in wood
 Drilling in ceramics, plastics, fiberglass, and laminates
 Drilling in metals
 Mixing paint
SWITCH TRIGGER
See Figure 2, 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 delivers higher speed with in-
creased 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)
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.
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.
TO INSTALL BITS
See Figures 4 - 5, page 12
 Unplug the drill.
 Insert the chuck key and twist counterclockwise.
 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.
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 5.
This could cause the drill bit to be thrown from the
drill, resulting in possible serious personal injury or
damage to the chuck.
 Insert the drill bit.
 Tighten the chuck jaws securely on the drill bit, using the
chuck key provided.
 Remove the chuck key.
TO REMOVE BITS
See Figure 4, page 12
 Unplug the drill.
 Loosen the chuck jaws using the chuck key provided.
 Remove the drill bit.
 Remove the chuck key.
USING THE AUXILIARY HANDLE ASSEMBLY
See Figure 6, page 12.
Your drill is equipped with an auxiliary handle assembly. For
ease of operation, use the handle with either the left or right
hand. The handle can be rotated 360°.
To adjust the auxiliary handle assembly:
 Loosen the handle assembly by turning the handle coun-
terclockwise.
 Rotate the handle assembly to the desired operating
position.
 Securely tighten by turning the handle assembly clock-
wise.
NOTE: For convenience and ease of starting threads, the
hex nut has been trapped inside the molded slot in the
handle assembly.
LOCk-ON BUTTON
See Figure 7, page 13.
This drill is equipped with a lock-on feature, which is
convenient for continuous drilling for extended periods of
time.
