• 

latch pivot bolt, and the axle where the hitch tongue 
pivots, with a light machine oil.
At least once a season, grease or oil the wheel 

• 

bearings. Use automotive wheel bearing type grease 
or 20 weight oil.

WARNING: 

Always stop engine and 

disconnect spark plug wire before 
cleaning, lubricating or before performing 
any repairs or maintenance.

ENGINE MAINTENANCE

Only use high quality detergent oil rated with API service 

classification SF or SG. Select the oil's SAE viscosity 

grade according to your expected operating temperature. 
SAE 30 grade oil is recommended for warm weather use. 
For cold weather use refer to the engine manufacturer's 
Operating and Maintenance Manual.

Check 

• 

oil level

 before each use. Maintain engine oil 

as instructed in the separate engine manual. 
Service 

• 

air cleaner

 every 25 hours under normal 

conditions. Clean every few hours under extremely 
dusty conditions. Poor engine performance and 

flooding usually indicates that the air cleaner should 

be serviced. To service the air cleaner, refer to the 
separate engine manual.
The 

• 

spark plug

 should be cleaned and the gap reset 

once a season. Spark plug replacement at the start 
of each season is recommended. Check the engine 

manual for correct plug type and gap specifications.

Make sure the cart and top are cleaned after each 

• 

use. Grass clippings and leaves left in the cart will 
mildew and cause damage if not cleaned out.

Clean the engine

• 

 regularly with a cloth or brush. 

Keep the cooling fins on the engine housing clean 

to permit proper air circulation which is essential to 
engine performance and life. Be sure to remove all 

dirt and debris from muffler area.
