Vari-Torque Clutch
This clutching action is provided by the friction of the OUTER WASHER against the BLADE
and permits the blade shaft to turn when the blade encounters excessive resistance. When the
BLADE STUD is properly tightened (as described in No.5 of Attaching The Blade), the blade
will slip when it encounters excessive resistance, thus reducing saw's tendency to KICKBACK.
One setting may not be sufficient for cutting all materials. If excessive blade slippage occurs,
tighten the blade stud a fraction of a turn more (less than 1/8 turn). OVERTIGHTENING THE
BLADE STUD NULLIFIES THE EFFECTIVENESS OF THE CLUTCH.
