accurate pressure reading.
Rear Tire Pressure: 12–14 psi (83–97 kPa)

Adjusting the Electric Clutch
The clutch is adjustable to ensure proper engagement and
proper braking. Check adjustment after every 100 hours of
operation.
1. To adjust the clutch, tighten or loosen the lock nuts on
the flange studs (Fig. 42).
2. Check adjustment by inserting a feeler gauge thru the
slots next to the studs (Fig. 42).
3. The proper disengaged clearance between the clutch
plates is 0.012–0.024 inch (0.30-0.60 mm). It will be
necessary to check this clearance at each of the three
slots to ensure the plates are parallel to each other.
