PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE
THE RISK OF FIRE, ELECTRIC SHOCK, AND PERSONAL
INJURY, INCLUDING THE FOLLOWING:
READ ALL INSTRUCTIONS.
1.
KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.

Straight line or orbital cutting action
Conventional

also cuts in this manner but, for softer
workpieces, an orbital cutting action can
be selected. Soft workpieces like wood and
plastic permit deep penetration of indivi-
dual saw teeth. The orbital action thrusts
the blade forward on the cutting stroke
and greatly increases cutting speed over
conventional jig saws. Harder workpieces
like metal should be cut using the straight
line cutting action or

Operation
Turn the tool on and wait until the blade
attains full speed. Then rest the base flat
on the workpiece and gently move the tool
forward along the previously marked cutting line. When cutting curves, advance the
tool very
slowly.

CAUTION
:
Failure to hold the tool base flush with the workpiece may cause blade breakage.
Bevel cutting
With the base tilted, you can make bevel
cuts
at
any angle between
0"
and
45"
(left
or right).
Loosen the bolt on the back of the base
with the hex wrench and slide the base
backwards. Tilt the base to the desired
angle. The edge
of
the housing indicates
the bevel angle.
Then check the contact between the back
edge of the blade and the roller.
Now
tighten the bolt securely on the back
of the base.
