I must have not made myself clear! The problem with the Saw had nothing
to do with the Cutoff Switch.
The problem was that the Blade was jamming in the Cut in the Material.
The Switch, I was referring to, is in the Motor. It is a Centrifugal
Switch that Capacitor Start Induction Motors have. This Switch is closed
when the motor is not running, When power is applied to the motor,
Electrical Current flows through the Start Winding and causes the motor
to start spinning. When the running speed is obtained, the Internal
Switch opens and no more Current flows through the Start Winding. (if
current flows for an extended time in the start winding, the motor will
overheat and be ruined)
When the Blade would hang in the Material, the Motor would slow down
because of the Load. When that happened, the Internal Start Switch would
close, and the additional torque from the Start Winding would cause the
Motor to pull the Blade through the Material. Then the Motor would come
back to speed and the Switch would open until the jam occured again on
the next pass of the Blade. (the clicking noise i heard was this switch,
closing and opening))
The only time I have found that the Cutoff Switch did not function right
and cut the Saw off at the end of the cut, is when parts of the Vise and
the Blade Guides touched each other, and prevented the Frame from
pressing on the Cutoff Switch.
Excuse the loooong post!
