Servicing the Air Cleaner
Service Interval:
Before each use or daily
Every 500 hours
Servicing the Primary Air Filter
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 primary air-cleaner filter only when the
service indicator (
) 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 that the cover is seated
correctly and seals with the air-cleaner body.

Check the filter blockage indicator. If the
indicator is red, replace the air filter (

2.
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.
Remove the cover from the air-cleaner body.
Note:
This cleaning process prevents debris
from migrating into the intake when you remove
the filter.
