Oil Filter Change
The oil filter should be changed along with the
engine oil.
Spin-on Filter:
1. Remove the filter.
2. Apply oil to the rubber ring of the new filter
and install the filter.
3. Tighten the filter until the rubber ring makes
contact, and then tighten it 1/2 turn more.
Crankcase Breather
The crankcase breather system ducts crankcase
gases formed in the crankcase directly to the air
intake. Harmful vapors that would otherwise
collect in the crankcase and contaminate the oil,
or escape to the outside, are drawn back into the
engine and burned. The breather hose should be
inspected yearly to make sure it is not plugged.
Engine Air Cleaner
Oil Bath Type
A heavy duty, oil bath air cleaner filters all of the
air entering the engine. Excessive restriction of
the air intake system reduces the flow of air to the
engine affecting horsepower output, fuel
consumption and engine life.
The air cleaner removes abrasive material from
the air entering the engine. The air cleaner must
be kept clean and open so that the air can pass
freely. If the oil has absorbed the maximum
amount of dirt, it allows the dirt to enter the
engine. Remove the oil cup, wash thoroughly and
dry every 1000 operating hours (500 hours under
dusty conditions). Refill using the same weight oil
used in the engine crankcase. Inspect the cleaner
body and wash in solvent when it becomes dirty.
