5.5 BLADE BRAKE/ELECTRIC CLUTCH ADJUSTMENT
The blade switch engages the electric clutch when
pulled out to the “ON” position. When the blade
switch is in the “ON” position the cutting blade(s)
are engaged. The blade switch disengages the
electric clutch when the blade switch is pushed in
to the “OFF” position. When the blade switch is in
the “OFF” position the cutting blade(s) are
disengaged. The electric clutch is adjustable. The
blades should stop rotation in 7 seconds or less. If
the electric clutch fails to stop the blades rotation in
7 seconds, adjustment is necessary.
1. Insert a feeler gauge into the three slots on the
electric clutch.
2. Check gap through all three slots in the side of
the clutch. The gap should be set at .015.
3. If gap is incorrect rotate nuts in or out to achieve
the correct gap. See Figure 5.11.
NOTE: Electric Clutch is shown removed from the
machine. Removal is not necessary for adjustment.
