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 .016" feeler gauge should 
slide between armature and rotor with 
slight contact.
Maximum: A .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 .016" feeler gauge fits 
between armature and rotor.

2. Slide a .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.

NOTE: 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.

NEVER spray unit with high-pressure water 
or store unit outdoors.
Inspect unit for visible signs of wear, 
breakage or damage.
Keep all nuts, bolts and screws properly 
tightened and know unit is in safe working 
condition.
Store unit in a cool, dry protected area.

Clean unit thoroughly with mild soap and low 
pressure water and lubricate (See Lubricate 
Unit on page 24 in Maintenance). Touch up 
all scratched painted surfaces.
Remove weight from wheels by putting 
blocks under frame or axle.
When storing unit for extended periods of 
time, remove all fuel from tank and carburetor 
(run dry). Refer to Engine Manual.
Clean and charge the battery. Charge battery 
every three to four weeks when storing unit.

Gasoline left in the fuel system for extended 
periods without a stabilizer will deteriorate, 
resulting in gum deposits in the system. 
These deposits can damage the carburetor 
and the fuel hoses, filter and tank. Prevent 
deposits from forming in the fuel system 
during storage by adding a quality fuel 
stabilizer to the fuel. Follow the 
recommended mix ratio found on the fuel 
stabilizer container.
To treat the fuel system for storage:

1. Add fuel stabilizer according to 

manufacturers’ instructions.

2. Run engine for at least 10 minutes after 

adding stabilizer to allow it to reach the 
carburetor.

NEVER store the engine with fuel in the fuel 
tank inside of a building with potential 
sources of ignition.

1. Refer to the engine service manual to 

prepare the engine for service.

2. Put fresh, clean fuel in the fuel tank.
3. Begin the maintenance schedule. 
4. Charge and install the battery.
