FUEL FILTER: Inspect the in-line fuel filter daily. When necessary remove the sediment bowl from beneath the gas tank and clean out any accumulated dirt and water. Change the fuel filter after the first 50 hours of opera- tion and every 500 hours thereafter.

AIR CLEANER: The Continental engine is equipped with a dry type air filter. Inspect the air cleaner daily - more often in dusty conditions. Never remove the air filter while the engine is running. Never apply oil to the air cleaner. Clean every 50 hours. Every 250 hours (more frequently in extreme dust conditions) replace the air cleaner as follows:

1.Loosen the wing nut and remove the cover and the filter element. Do not allow dirt to fall into the exposed carburetor. Gently tap the element flat on a smooth surface.

2.If dust is sticking to the dust collector element, blow compressed air through it from the inside out. Turn the element as you apply air. Air pressure should be under 2 bar (30 psi).

3.Check the element for damage before reassem- bling the air cleaner. Replace the element if it appears damaged. The air cleaner element part number is Donaldson #181050 or Nelson #70206N.

COOLING SYSTEM: The Continental engine is water cooled. Check the coolant level at the radiator filler daily. Add a 50-50 mixture of water and antifreeze as needed. To drain and refill the system, do the following:

1. Ensure that the machine is on level ground.

WARNING

To avoid personal injury, never remove the radiator pressure cap nor the reserve tank cap while the engine is running or immediately after it has stopped. Hot water may gush out, which can scald people nearby.

2.Remove the radiator filler cap.

3.Remove the drain plug or cock from the side of the cylinder block in order to drain the engine. Ensure that the drain hole is not restricted. See Figure D.2A.

4.Open the radiator drain cock at the bottom of the radiator in order to drain the radiator. See Figure D.2B.

5.If necessary, flush the system with clean water.

6.Replace the engine drain plug and the radiator drain cock.

7.Fill the cooling system at the radiator filler with a 50- 50 mixture of water and antifreeze. (Capacity: 9.3 quarts/8.8 liters.)
