Operating Instructions for Saw
Disconnect the plug from
the power source before
making any assembly, adjustments or
changing accessories. Such preventive
safety measures reduce the risk of starting
the tool accidentally.
When working, never hold tool with your
hand or fingers in area of the saw blade. The
fingers of the guiding hand must always be
kept behind the limiting ridge (Fig. 14).
SLIDE "ON-OFF" SWITCH
The tool is switched "ON" by the slide
switch located at the side of the motor
housing. The switch can be locked in the
"ON" position, a convenience for long
cutting operations.
TO LOCK THE SWITCH "ON", slide the
switch button forward and press "IN" the
FRONT portion.
TO UNLOCK THE SWITCH, simply press
and release the REAR portion of the button.
The switch is spring loaded and will snap
back automatically.
VARIABLE SPEED DIAL
Your tool is equipped with a variable speed
dial. The blade stroke rate may be adjusted
during cutting operation by setting the dial on
or between any one of the six numbers.
Application Position
Softwood 3 - 6
Hardwood 4 - 6
Plastic 1 - 6
The optimum stroke rate depends on the
material and must be determined by testing
on similar materials in each application.
POSITIONING THE BLADE
AGAINST THE WORK
Never saw with the blade facing upward or
in the direction of the body (Fig. 15).
The cutting action of this saw is similar to a
handsaw.
Place the blade on the edge of the work-
piece. The blade should be held at a steep
angle to the workpiece approx. 60° (Fig. 16A.)
It is difficult to begin cutting on the flat of a
workpiece (Fig.16B).
Pull blade thru the workpiece maintaining a
steep angle when cutting (Fig. 17A).
Do not start cutting on the back edge and
allow tip to plunge into workpiece (Fig. 17B)
