VARI-TORQUE CLUTCH
This clutching action is provided by the
friction of the outer washer 30 against the
blade 29 and permits the blade shaft 27 to
turn when the blade encounters excessive
resistance. When the blade stud 25 is
properly tightened (as described in step I
of "Attaching The Blade"), the blade will
slip when it encounters ex cessive
resistance, thus reducing saw's tendency
to kickback.
One setting may not be sufficient for
cutting all materials. If ex cessive blade
slippage occurs, tighten the blade stud a
fraction of a turn more (less than 1/8 turn).
