Engine Maintenance

Engine Safety

Shut off the engine before checking the oil or adding oil to
the crankcase.

Servicing the Air Cleaner

Service Interval: Every 400 hours
Check the air-cleaner body for damage that 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 only when the service indicator
(Figure 38) requires it. Changing the air filter before it is
necessary only increases the chance of dirt entering the engine
when you remove the filter.
