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:
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 alu-
minum, 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 7.
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.
USING THE LASER GUIDE
See Figure 7.
WARNING:
Do not stare into the laser beam. Failure to heed this
warning could result in possible serious personal injury.
The laser unit comes from the factory already installed
and aligned. If the laser becomes misaligned after time
refer to the Adjustments section.
The jig saw is equipped with a laser guide to project a red
line to show the cut path.

Pull the switch trigger to engage the laser guide.
 The laser guide will turn on with the jig saw and continue
to stay on for the cutting operation.
 The laser guide will turn off when the switch trigger is
released.
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.
