Adjusting the Electric Clutch

Service Interval: Every 100 hours—Check the electric
clutch.
The clutch is adjustable to ensure proper engagement and
proper braking.
1. Insert a 0.4 to 0.5 mm (0.01 to 0.02 inch) feeler gauge
through an inspection slot in the side of the assembly.
Note: Make sure that it is between the armature and
the rotor friction surfaces.
Note: The gap needs to be at least 0.4 mm (0.02
inches) and not more than 0.5 mm (0.02 inches).
2. If adjustment is needed, use a 0.4 mm (0.02 inches)
feeler gauge to set each of the 3 adjustment-slot
positions.
3. Tighten the lock nuts until there is slight binding on
the feeler gauge but it can be moved easily within the
air gap (Figure 60).
4. Repeat this for the remaining slots.
5. Check each slot again and make slight adjustments until
the feeler gauge is between the rotor and armature with
very slight contact between them.
