Engine Maintenance

Servicing the Air Cleaner

Service Interval: Every 200 hours
•
Check the air-cleaner body for damage which could cause
an air leak; replace it if it is damaged. Check the whole
intake system for leaks, damage, or loose hose clamps.
•
Service the air-cleaner filter before 200 hours if the
engine performance suffers due to extremely dusty, dirty
conditions. Changing the air filter before it is necessary
only increases the chance of dirt entering the engine when
the filter is removed.
•
Ensure that 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

2. Remove the cover from the air-cleaner body.
3. Before removing the filter, use low pressure air (40 psi,
clean and dry) to help remove large accumulations of
debris packed between the outside of the primary filter
and the canister. This cleaning process prevents debris
getting into the intake when you remove the primary
filter.
Important: Avoid using high pressure air which
could force dirt through the filter into the intake
tract.
4. Remove and replace the primary filter, as follows:.
Important: Do not clean the used element.
A. Inspect the new filter for shipping damage; do
not use a damaged element.
