They may cause deteriora- tion of the cartridge. Do not oil cartridge. Do not use pressurized air to clean or dry cartridge. ENGINE OIL FILTER Replace the engine oil filter every season or every other oil change if the tractor is used more than 100 hours in one year. Unscrew old filter by turning counter- clockwise. Use a suitable container to catch oil. Apply a thin coating of new engine oil to rubber gasket on replacement oil filter.
Install replacement oil filter by turning clockwise until rubber gasket contacts mounting surface, then tighten filter an additional 1/2to 3/4 turn. Fill crankcase with new oil (See "TO CHANGE ENGINE OIL" in this section of this manual). For approximate capacity see "PRODUCT SPECIFICA- TIONS" section of this manual. Start engine and check for oil leaks. Correct any leaks before placing engine into full operation.

Engine Cooling Air Guide Cover (Both Sides) _ Filter 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 automo- tive type wax.
