LUBRICATION

Lubricate the pivot points on the chute deflector and chipper chute once a season using a light oil.

ENGINE

ENGINE OIL

Only use high quality detergent oil rated with API ser- vice classification SG. Select the oil's viscosity grade according to your expected operating temperature.

Colder ,,i	32°F	= Warmer
5W30		SAE 30

NOTE: Although multi-viscosity oils (SE30, 10W30, etc.) improve starting in cold weather, these multi-vis- cosity oils will result in increased oil consumption when used above 32°F. Check your oil level more fre- quently to avoid possible engine damage from run- ning low on oil.

Your four-cycle engine will normally consume some oil--therefore, check engine oil level regularly approx- imately every five hours of operation and before each usage. Stop engine and wait several minutes before checking oil level. With engine level, the oil must be to FULL mark on dipstick (refer to figure 7). Change engine oil after the first five hours of operation, and every twenty-five hours thereafter.

To Drain Oil:

•Drain oil while engine is warm.

a. Remove oil drain plug. Refer to figure 7. Catch oil in a suitable container.

b.When engine is drained of all oil, replace drain plug securely.

•Refill with fresh oil. Refer to GAS AND OIL FILL- UP section.

•Replace dipstick.

AIR CLEANER

The air cleaner prevents damaging dirt, dust, etc.,

from entering the carburetor and being forced into the

engine and is important to engine life and per- formance.

Never run your engine without air cleaner com- pletely assembled.

To Service Air Cleaner:

Service pre-cleaner after every 25 hours of use, or at least once a season. Service cartridge every 100 hours of use, or at least once a season. Service pre-

cleaner and cartridge more often under dusty condi- tions.

Loosen screw and remove cover.

To service pre-cleaner, wash in liquid detergent and water. Squeeze dry in a clean cloth. Saturate in engine oil. Squeeze in a clean, absorbent cloth to remove all excess oil. If pre-cleaner is very dirty, replace it.

•To service cartridge, clean by tapping gently on a flat surface. If very dirty, replace. Do not oil car- tridge.

NOTE: Do not use petroleum solvents (e.g. kerosene) or pressurized air to clean cartridge. They will cause cartridge to deteriorate.

•Reinstall cartridge and pre-cleaner.

•Replace cover, and tighten screws securely.

CLEAN ENGINE

Clean engine periodically. Remove dirt and debris

with a cloth or brush. Cleaning with a forceful spray of water is not recommended as water could contami-

nate the fuel system.

Yearly or every 25 hours, whichever occurs first, remove the blower housing and clean the areas shown in figure 11 to avoid overspeeding, overheating and engine damage. Clean more often if necessary.
