Air screen must be kept free of dirt and chaff to prevent
engine dam age from overheating. Clean with a wire brush
or compressed air to re move dirt and stubborn dried gum
fibers. See engine manual.
AIR FILTER
Your engine will not run properly using a dirty air filter. Clean
the foam pre-cleaner after every 25 hours of op er a tion or

Use gauge on oil fill cap/dipstick for checking level.
Be sure dipstick cap is tightened securely for accurate
reading. Keep oil at “FULL” line on dipstick. Tighten
cap onto the tube securely when finished.

CLEANING
Clean engine, battery, seat, finish, etc. of all foreign
matter.
Keep finished surfaces and wheels free of all gasoline,
oil, etc.
Protect painted surfaces with automotive type wax.
We do not recommend using a garden hose or pressure
washer to clean your tractor unless the engine and trans-
mission are covered to keep water out. Water in engine or
transmission will shorten the useful life of your tractor. Use
compressed air or a leaf blower to remove grass, leaves
and trash from tractor and mower.
