General Air Cleaner
Maintenance
• 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 every 200 hours or earlier if
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.
• Be sure the cover is seated correctly and seals with the
air cleaner body.

2. Release latches securing air cleaner cover to air cleaner
body.
3. 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 primary 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 primary filter is removed.
4. Remove and replace the primary filter. 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
