Air Cleaner Service

The engine has a replaceable high-density paper air cleaner element with an oiled foam precleaner. See Figure 44.
Figure 44 Air Cleaner Components
Check for a buildup of dirt and debris around the air cleaner system. Keep this area clean. Also check for loose or damaged
components. Replace all bent or damaged air cleaner components.
Note:
Operating the engine with loose or damaged air cleaner components could allow unfiltered air into the engine causing premature
wear and failure.
Precleaner Service
Use the following procedure to wash and oil the precleaner as indicated in the service schedule. Wash and oil the precleaner
more often under extremely dusty or dirty conditions.
1. Press the OFF button on the generator set controller.
2. Disconnect the AC power to the generator set.
3. Disconnect the engine starting battery, negative (–) lead first.
4. Loosen the cover knob and remove the air cleaner cover. Remove the precleaner from the paper element. Wash the
precleaner in warm water with detergent. Rinse the precleaner thoroughly until all traces of detergent are eliminated.
Squeeze out excess water (do not wring). Allow the precleaner to air dry.
5. Saturate the precleaner with new engine oil. Squeeze out all of the excess oil.
6. Reinstall the precleaner over the paper element.
7. Reinstall the air cleaner cover. Secure the cover with the cover knob.
