VACUUM ADAPTOR INSTALLATION (FIG 3)
Your jig saw comes with a vacuum adaptor (8). This attachment allows you to connect it to a standard 1-1/2"
vacuum hose.
To connect the vacuum adaptor to the tool, insert the smaller side
of vacuum adaptor into the base opening as shown in fIG 3. There
are two raised stops on the flat side of the vacuum adaptor for
positioning. You may use force to push the vacuum adaptor into
its working position.
OPErATION
SWITCH ACTION
WArNING:
adjusting or checking function on the tool. The switch can be locked in the "ON" position
for ease of operator comfort during extended use. Use caution when locking tool in the
"ON" position and maintain a firm grasp on the tool.
This jig saw is equipped with an "ON/Off" trigger switch (1) which is operated by squeezing or releasing, and a
lock-on button (2) for extended use.
To Start the Saw,
depress the switch (1). for extended use, you may set lock-on button to relieve the fatigue.
Depress the switch to the max speed, depress the lock-on button to lock the switch on. To release the lock-on
button, depress the switch.
To Stop the Saw,
release the switch. If the lock-on button is in use, depress the switch first and then release
it to stop the saw.
SPEED ADJUSTMENT DIAL
Your jig saw is equipped with a speed adjusting dial located on the upper, forward portion of the saw's handle.
Tool speed can be infinitely adjusted between 0 and 3,000 strokes per minute by rotating the adjusting dial.
Speed indicators appear on the dial as the numbers 1 through "MAX": 1 is the slowest saw speed and "MAX"
represents the highest speed. Therefore, Speed Increases as you rotate the dial towards "MAX". Speed decreases
as you rotate the dial towards "MIN". The speed adjusting dial can be operated while the saw is running or when
the saw is not operating. The operator has the ability to preset the saw's speed by rotating the dial to the desired
setting and then fully depressing the trigger switch, turning the saw on for use. Please note: regardless of pressure
applied on the trigger, the tool will not operate any faster than the maximum speed setting selected. Be aware that
when the jigsaw is operated at low speed the motor temperature will begin to rise due to the slower speed of the
internal cooling fan. In such cases, it is necessary to occasionally run the tool at full speed for a few minutes to
aid internal cooling to keep the motor operating at high efficiency.
The jig saw cutting speed (or stroke rate) required depends on the material being cut, the type of blade being used,
and the feed rate used by the operator. The best speed for a particular application is largely based on operator
experience or experimentation. However, as a general rule, slower speeds are for denser materials and faster
speeds for soft materials. Saw blade life is also largely determined by the motor speed and the type of material
being cut. The following chart is intended as a guideline only; test cuts in scrap should be performed first to
determine the best speed setting.

SELECTING THE ORBITAL CUTTING ACTION
This jigsaw can be operated in the conventional straight line (up and down) mode or with an "orbital" cutting
action. During orbital cutting, the blade is thrust forward on the upward (cutting) stroke, greatly increasing cutting
speed. During the down stroke, the blade is cleared of accumulated debris, enhancing cutting efficiency and
extending blade life by causing the blade to run cooler. The orbital action adjustment switch is located on the
Variable-Speed Orbital-Action Jig Saw
