Engine Maintenance

Servicing the Air Cleaner

Check the air cleaner body for damage which could
cause an air leak. Replace if damaged. Check the whole
intake system for leaks, damage or loose hose clamps.
Service the air cleaner filter only when the service
indicator (Figure 59) requires it. Changing the air filter
before it is necessary only increases the chance of dirt
entering the engine when the filter is removed.
Important: Be sure the cover is seated correctly
and seals with the air cleaner body.
1. Release the latches securing the air cleaner cover to
the air cleaner body (Figure 59).

2. Remove the cover from the air cleaner body. Before
removing the filter, use low pressure air (40 psi,
clean and dry) to help remove large accumulations
of debris packed between outside of the filter and
the canister. Avoid using high pressure air which
could force dirt through the filter into the intake
tract.
This cleaning process prevents debris from migrating
into the intake when the filter is removed.
3. Remove and replace the filter (Figure 60).
Cleaning of the used element is not recommended
due to the possibility of damage to the filter media.
Inspect the new filter for shipping damage, checking
the sealing end of the filter and the body. Do not
use a damaged element. Insert the new filter by
applying pressure to the outer rim of the element to
seat it in the canister. Do not apply pressure to the
flexible center of the filter.

4. Clean the dirt ejection port located in the removable
cover. Remove the rubber outlet valve from the
cover, clean the cavity and replace the outlet valve.
5. Install the cover orienting the rubber outlet valve in
a downward position—between approximately 5:00
to 7:00 when viewed from the end.
6. Secure the latches.
Servicing the Engine Oil and
Filter
Change the engine oil and filter initially after the first 50
hours of operation and every 150 hours thereafter.
1. Remove the drain plug (Figure 61) and let the oil
flow into a drain pan.
