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" 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
