5.5BLADE 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" posi- tion 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.
