5. Reinstall the dipstick/oil fill plug and tighten
securely. See Figure 19.
NOTE: Over tightening the dipstick/oil fill plug
will distort the gasket and may cause oil
weeping.
Oil Sentry™
Some engines are equipped with an optional Oil
Sentry™ oil level switch. If the oil level drops below
an acceptable level, the Oil Sentry™ will either shut off
the engine or activate a warning signal, depending on
the application.
NOTE: Check the oil level BEFORE EACH USE and
maintain to the correct level. This includes
engines equipped with Oil Sentry™.
Service Precleaner and Air Cleaner
Element
These engines are equipped with a replaceable, high
density paper air cleaner element. Some engines
are also equipped with a foam precleaner which
surrounds the paper element. See Figure 20.
Check the air cleaner daily or before starting the
engine. 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.
Service Precleaner (if equipped)
Wash and dry the precleaner every 50 hours of
operation (more often under extremely dusty or dirty
conditions).
1. Remove the top wing nut and air cleaner cover.
See Figure 20.
2. Remove the wing nut and special washer.
3. Remove the precleaner from the paper element.
4. 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. Do not oil precleaner.
5. Reinstall the precleaner over the paper element.
6. Slide the precleaner and paper element onto the
air cleaner stud. Secure with special washer and
wing nut. See Figure 20.
7. Reinstall the air cleaner cover and secure with
wing nut.
