OPERATION
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 4, page 11.
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.
GENERAL CUTTING
Rest the front of the saw base on the workpiece and align
cutting edge of the blade with the line on your workpiece.
Make sure the power cord is out of your way and not in the
line of cut. Start the saw and move it forward on the work
surface. Apply downward pressure to keep the saw steady
and only enough forward pressure to keep the blade cutting.
Do not force the saw. Applying too much forward pressure
to the saw may overheat the motor and break saw blades.
ORBITAL MOTION
See Figures 5 and 6, page 11 - 12.
The blade of the saw cuts in an orbital motion. This feature
is adjustable and provides faster, more efficient cutting. With
orbital motion the blade cuts through your work in the upstroke
but does not drag across your work in the downstroke. To
adjust the orbital motion, rotate the orbital adjustment knob
to the desired setting. Refer to the chart in Figure 6 to find
the right setting for the job you are attempting.
NOTE: Setting the orbital position to a lower setting will
result in a smoother finish but slower cut. A higher setting
will result in a rougher finish but faster cut.
 Rotate the rapid change blade clamp so that the slot in
the blade clamp is aligned with the slot in the blade sup-
port roller.
 Remove the blade.
STARTING/STOPPING THE SAW
See Figure 2, page 11.
To turn the saw
ON, depress the switch trigger. Release the
switch trigger to turn the saw OFF.
LOCK-ON BUTTON
See Figure 2, page 11.
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
(depress and release switch trigger). Failure to do so
could result in accidental starting of the saw resulting in
possible 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 3, page 11.
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 3.
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.
