WARNING: Do not attempt to operate this tool
until you have read thoroughly and understand
completely all instructions, safety rules, etc.,
contained in this manual. Failure to comply can
result in accidents involving fire, electric shock,
or serious personal injury. Save owner's manual,
and review frequently for continuing safe opera-
tion and for instructing others who may use this
tool.
VARIABLE SPEED
See Figure 4.
Your saw has a variable speed control selector
designed to allow operator control and adjustment of
speed and power limits. The speed and power of your
saw can be increased or decreased by rotating the
variable speed control selector in the direction of the
arrows shown in Figure 4.
SWITCH
See Figure 3.
To turn your saw ON, depress the switch trigger.
Release switch trigger to turn your saw OFF.
LOCK-ON Bu'n'ON
LOCK-ON Bu'n'ON
See Figure 3.
Your saw is equipped with a lock-on feature, which is
convenient when continuous cutting is required for
extended periods of time. To lock-on, depress the
switch trigger; push in and hold the lock-on button,
located on the side of the handle; then release the
switch trigger. Release lock-on button and your saw
will continue running.
To release the lock, depress the switch trigger and
release.
If you have the lock-on feature engaged during use
and your saw becomes disconnected from the power
supply, disengage the lock-on feature immediately.
_, WARNING: Before connecting your saw to the
power supply source, always check to be sure it
is not in lock-on position (depress and release
switch trigger). Failure to do so could result in
accidental starting of your saw, resulting in
possible serious injury. Also, do not lock the
trigger on jobs where your saw may need to
be stopped suddenly.

Note: Hold your saw in normal operating position and
turn the variable speed control selector counterclock-
wise to increase speed and power. Turn clockwise 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.
Note: If the variable speed control selector is fully
turned in the clockwise direction (zero setting), your
saw may not run.
Note: If you desire not to use the variable speed
control selector, turn it in the full counterclockwise
direction. This will allow the speed of your saw to be
controlled by the amount of switch trigger depression.
Avoid running your saw at low speeds for extended
periods of time. Running at low speeds under con-
stant usage may cause your saw to become over-
heated. 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:
Low 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.
High speed produces best results when maximum
power is required. For example, cutting wood. Soft
metals such as aluminum, brass, and copper also
require high speeds.
