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

WARNING
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.
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.
