OPERATION
APPLICATIONS
You may use this product for the purpose listed below:
 Sawing non-ferrous metal, sheet steel, wood, plastic, and
similar materials.
SWITCH
See Figure 2, page 13.
To turn the saw ON, depress the switch trigger. Release
switch trigger to turn the saw OFF.
LOCk-ON BUTTON
See Figure 2, 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
(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 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 as shown in figure 3.
NOTE: Hold the saw in normal operating position and turn
the variable speed control selector to the higher letters to
increase speed and power. Turn to the lower letters to de-
crease 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 the saw to become overheated. If this occurs, cool
the 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 (Settings A and B): Ideal when minimum speed
and power is required; for example, starting cuts.
MEDIUM Speed (Settings C and D): Suitable for cutting
hard metals, plastics, and laminates.
HIGH Speed (Settings E and F): 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.
CHIP SHIELD
See Figure 4, page 13.
For your protection, a chip shield has been included with
the saw. It is used to shield wood particles from the eyes.
The chip shield is attached by placing it in front of the blade
area of the base and snapping it into the tabs on the sides
of the saw base. For removal, simply pull on the chip shield
by gripping the same tabs as shown in figure 4. Make sure
the saw is unplugged before installation and removal.
WARNING:
To avoid serious personal injury, do not use saw
without chip shield properly in place.
NO-MAR BASE PLATE
See Figure 5, page 14.
Since the base of the jig saw is bare metal, to protect a deli-
cate work surface, install the plastic no-mar base plate to
cover the metal base by snapping the plate into the bottom
of the base. The plate is made of plastic and has a smooth
finish, making it easier to glide the tool along the work sur-
face without marring it.
To remove, pull the plate from the grooves on the bottom
of the jig saw base.
DUST COLLECTION VACUUM ATTACHMENT
See Figure 6, page 14.
For dustless operation, a dust collection vacuum attach-
ment has been provided with the saw which attaches to
the saw base.
To Install:
 Unplug the saw.
 Slide the dust collection vacuum attachment into the
curved area at the rear of the base.
To Remove:
 Unplug the saw.
 Remove the dust collection vacuum attachment by pulling
attachment from base.
NOTE: The dust collection vacuum attachment should not
be used with the base in beveling position. See Bevel Cut-
ting.
