OPERATION

VARIAbLE SPEED
See Figure 5, page 14.
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 your saw can be increased
or decreased by rotating the variable speed control selector
in the direction of the arrows shown in figure 5.
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 trigger switch, push in and hold the lock-on button, and
release the trigger switch. Next, adjust the variable speed
control selector until the desired speed is reached.
Avoid running your 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:
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 may also require high speeds.

wARNINg:
Before connecting the saw to power supply, always
check to be sure it is not in lock-on position (depress and
release trigger switch). Failure to comply could result in
accidental starting and possible serious injury. Also, do
not lock the trigger on jobs where the saw may need to
be stopped suddenly.
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.
