LINE GUIDE
For a straight 90° cut, use right side of notch
in the foot. For 45°-56° bevel cuts, use the left
side (Fig. 7). The cutting guide notch will give
an approximate line of cut. Make sample cuts
in scrap lumber to verify actual line of cut. This
will be helpful because of the number of
different blade types and thicknesses
available. To ensure minimum splintering on
the good side of the material to be cut, face
the good side down.
SWITCH
When starting the tool,
WARNING
!
hold it with both hands. The
torque from the motor can cause the tool to
twist.
To turn tool "ON", squeeze the trigger switch.
To turn the tool "OFF", release the trigger
switch, which is spring loaded and will return
to the off position automatically.
Your saw should be running at full speed
BEFORE starting the cut, and turned off only
AFTER completing the cut. To increase
switch life, do not turn switch on and off while
cutting.
GENERAL CUTS
Always hold the saw handle with one hand
and the auxiliary handle or housing with the
other.
Always be sure either hand

does not interfere with the
free movement of the lower guard.
Maintain a firm grip and operate the switch
with a decisive action. Never force the saw.
Use light and continuous pressure.
After completing a cut and

the trigger has been
released, be aware of the necessary time it
takes for the blade to come to a complete
stop during coast down. Do not allow the
saw to brush against your leg or side,
since the lower guard is retractable, it
could catch on your clothing and expose
the blade. Be aware of the necessary
blade exposures that exist in both the
upper and lower guard areas.
When cutting is interrupted, to resume
cutting: squeeze the trigger and allow the
blade to reach full speed, re-enter the cut
slowly and resume cutting.

BEVEL
When cutting across the grain, the fibers of
the wood have a tendency to tear and lift.
Advancing the saw slowly minimizes this
effect. For a finished cut, a cross cut blade or
miter blade is recommended.
CUTTING MASONRY/METAL
This tool is not recommended for continuous
and general usage with metal or masonry cut-
off wheels. If you use your saw for cutting
these materials, use the appropriate wheel for
the material being cut.
When cutting masonry, do not cut a depth of
more than 1/4 inch (6 mm). Make successive
passes to achieve desired depth. Apply a
light forward pressure. Do not overload
motor. Disconnect plug from power source
and clean dust from air vents frequently.
Metal cutting is done at full depth.
Clean guards frequently to
WARNING
!
assure a rapid return of
lower guard. The lower guard may become
sluggish when cutting masonry materials.
Abrasive Cut Off Wheels

!
must have a maximum
safe operating speed greater than the "no
load RPM" marked on the tool's
nameplate. Wheels running over the rated
speed can fly apart and cause injury.
Do not use the abrasive
