CUSTOMER RESPONSIBILITIES
V-BELTS
Check V-belts for deterioration and wear after 100 hours and
replace if necessary. The belts are not adjustable. Replace
belts if they begin to slip from wear.
TRANSAXLE COOLING
Keep transaxle free from build-up of dirt and chaff which can
restrict cooling.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service
classification SF-SJ. Select the oils SAE viscosity grade
according to your expected operating temperature.

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32°F. Check your engine oil level more frequently to avoid
possible engine damage from running low on oil.
Change the oil after every 50 hours of operation or at least
once a year if the tractor is not used for 50 hours in one year.
Check the crankcase oil level before starting the engine and
after each eight (8) hours of operation. Tighten oil fill cap/
dipstick securely each time you check the oil level.

until bright.
Coat terminals with grease or petroleum jelly.

engine damage from overheating. Clean with a wire brush or
compressed air to remove dirt and stubborn dried gum fibers.
