CLEANING

•     Clean engine, battery, seat, fi nish, etc. of all foreign 

matter.

•      Keep fi nished 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.

CLEAN AIR SCREEN 

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 
fi bers.

AIR FILTER 

Your engine will not run properly using a dirty air fi lter. 
Service air cleaner more often under dusty conditions. See 
Engine Manual.
