comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes and other possible
serious injuries.
WARNING:
Do not use any attachments or accessories not recom-
mended by the manufacturer of this tool. The use of at-
tachments or accessories not recommended can result
in serious personal injury.
APPLICATIONS
You may use this product for the purposes listed below:

Cutting all types of wood products (lumber, plywood,
paneling, composition board and hard board)

Cutting thin sheet metal (metal cutting blade not
included)

Cutting plastics and laminates
STARTING / STOPPING THE SAW
See Figure 3, page 13.
To turn the saw
ON, depress the switch trigger. Release the
switch trigger to turn the saw
OFF.
LOCK-ON BUTTON
See Figure 3, page 13.
The saw is equipped with a lock-on feature which is con-
venient when continuous cutting for extended periods of
time is required.
To lock-on:

Depress the switch trigger.

Push in and hold the lock-on button located on the side
of the handle.

Release switch trigger.

Release lock-on button.
To release:


Depress the switch trigger to release.
If you have the lock-on feature engaged during use and the
saw becomes disconnected from power supply, disengage
the lock-on feature immediately.
WARNING:
Before connecting the saw to power supply source,
always check to be sure it is not in lock-on position (de-
press and release switch trigger). Failure to do so could
result in accidental starting of the saw resulting in pos-
sible serious injury. Also, do not lock the trigger on jobs
where the saw may need to be stopped suddenly.
VARIABLE SPEED CONTROL SELECTOR
See Figure 4, page 13.
The saw has a variable speed control selector designed to
allow operator control and adjustment of speed and power
limits. The speed and power of the saw can be increased or
decreased by rotating the variable speed control selector in
the direction of the arrows shown in figure 4.
NOTE: Hold the saw in normal operating position and turn the
variable speed control selector to the positive ( + ) symbol to
increase speed and power. Turn to the negative ( − ) symbol
to decrease speed and power.
If you desire to lock the switch on at a given speed, depress
the switch trigger, push in and hold the lock-on button, and
release the switch trigger. Next, adjust the variable speed
control selector until the desired speed is reached.
Avoid running the saw at low speeds for extended periods
of time. Running at low speeds under constant usage may
cause your saw to become overheated. If this occurs, cool
your saw by running it without a load and at full speed.
The following guidelines may be used in determining correct
speed for various applications:
SLOW speed is ideal when minimum speed and power is
required, for example, starting cuts.
MEDIUM speed is suitable for cutting hard metals, plastics,
and laminates.
MAX speed produces best results when maximum power
is required, for example, cutting wood. Soft metals such as
aluminum, brass, and copper may also require high speeds.
WARNING:
Do not insert saw blade into air vents. They could come
in contact with electrically live internal parts, and cause
electrical shock resulting in serious injury.
LED LIGHT
See Figure 5, page 13.
The LED light illuminates when the switch trigger is de-
pressed to give you a clear view of the cut line on your
work surface.
