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.

Your engine will not run properly using a dirty air fi lter.  Clean 
the foam pre-cleaner after every 25 hours of op er a tion or 
every season.  Service paper cartridge every 100 hours of 
op er a tion or every season, whichever occurs fi rst.

Service air cleaner more often under dusty conditions.

cloth and squeeze to remove excess oil.

NOTE:  Do not wash the paper cartridge or use pressurized 
air, as this will damage the cartridge.
