Disconnect battery pack from tool or place the switch in the locked or
W RNING
off position before making any assembly, adjustments or changing
accessories. Such preventive safety measures reduce the risk of starting the tool
accidentally.
PLUNGER SPEED
The jigsaw cutting speed or stroke rate
required depends on the material being cut,
the type of blade being used, and the feed rate
preferred by the operator.
The best speed for a particular application is
largely determined by experience though as a
general rule, slower speeds are for denser
materials and faster speeds for softer materials.
Note: that when the jigsaw is used at low
speed settings for an extended length of time,
the motor temperature will rise due to slower
speeds of the internal cooling fan. In such
cases, it is necessary to occasionally run the
tool at full speed for a few minutes to keep the
motor running at high efficiency.
SLIDE ON-OFF SWITCH
The tool is switched "ON" by the switch button
located at the side of the motor housing. The
switch locks in the "ON" position, a
convenience for continuous operation (Fig. 1).
TO TURN THE TOOL "ON" slide the switch
button forward.
TO UNLOCK THE SWITCH, slide the switch
button backward.
When the trigger is released it activates the
electrical brake to stop the blade quickly. This
feature is especially useful when making
repetitive cuts.
BLADE ORBIT SELECTOR LEVER
Maximum cutting efficiency can be obtained
by adjusting the blade orbit selector lever to
suit the material being cut.
The following chart will help you determine
which setting to use for your application. This
chart is intended as a guideline only, and test
cuts in scrap material should be performed
first to determine the best setting.
Operating Instructions
BRAKE
VARIABLE SPEED DIAL
Your Jigsaw is equipped with a variable speed
dial. The blade stroke rate may be adjusted
during cutting operation by presetting the dial
on or between any one of the six numbers.

Setting O
Hard materials such as
metals or thin sheet metals.
This setting can be used with
knife blades, grit edge
blades, rasp work. and down
cutting blades.
Setting 1
Soft materials where cleaner
cutting or delicate scrolling
work is performed.
Setting 2
Medium density materials
such as harder woods or
particle board. Soft materials
such as wood, plastics, etc.
and when fast cutting is more
important than a clean cut.
WORK LIGHT
Your tool is equipped with a work light for better
visibility during operation. Once the tool has
been turned on, the light can be turned on by
pressing the LED switch. When the tool is
switched off, the light turns off. (Fig 1)
