CLUTCH ADJUSTMENT
NOTICE:
Adjust clutch every 500 hours or
once per season if used less than 500 hours.
If clutch fails to engage or disengage properly
or begins to make abnormal noise, check the
air gap adjustment at the three inspection
slots.
To check:
1. Stop engine, remove key and wait for all
hot parts to cool.
2. Measure the air gap between the
armature and the rotor.
Minimum: A 0.4 mm (.016") feeler gauge
should slide between armature and rotor
with slight contact.
Maximum: A 0.5 mm (.020") feeler
gauge should slide between armature
and rotor with slight contact.
3. Repeat for each inspection slot.
To adjust:
1. If necessary, loosen gap adjustment nuts
until a 0.4 mm (.016") feeler gauge fits
between armature and rotor.
2. Slide a 0.5 mm (.020") feeler gauge
between armature and rotor.
3. Tighten gap adjustment nut until there is
slight contact on feeler gauge.
4. Repeat steps 1 – 3 at each inspection
slot.
NOTICE:
Adjust air gap as evenly as
possible.
5. Start unit, engage and disengage PTO.
6. Shut off unit.
7. Recheck air gap and adjust if needed.
SHORT-TERM STORAGE
IMPORTANT:
NEVER wash unit with high-
pressure water or store outdoors.
1. Allow unit to cool and clean with mild
soap and water.
2. Tighten all hardware to correct
specifications.
3. Inspect unit for visible signs of wear or
damage. Repair as needed.
4. Prepare fuel system for storage.
NOTICE:
Gravely recommends using a
quality fuel stabilizer in all fuel. Gasoline left
in the fuel system without a stabilizer, even
for short periods of time, deteriorates and
leaves gummy deposits in the system that
may damage the carburetor and fuel hoses,
filter and tank. For the best effectiveness, add
stabilizer to all fuel containers whenever
purchasing fuel. Add the stabilizer to the
container before adding fuel.
a. Add Gravely fuel stabilizer (see
on page 17) or
equivalent according to
manufacturer's instructions to the fuel
tank and any fuel containers with
remaining fuel.
b. Run engine outdoors for at least
5 minutes to allow stabilizer to reach
the carburetor.
