2. Remove the foam precleaner by sliding it up off the
paper element (See Figure 23).
3. Wash the precleaner in warm water with
detergent. Rinse the precleaner thoroughly until all
traces of the detergent are eliminated. Squeeze
out (do not wring) excess water in a dry cloth.
Allow the precleaner to air dry.
4. Saturate the foam precleaner with new engine oil.
Squeeze out all excess oil.
5. Reinstall the foam precleaner over the paper
element.
6. Reinstall the air cleaner cover and secure with the
retaining knob.
Servicing the Paper Element
Inspect the paper element before each use. Every 100
hours of operation (more often under extremely dusty
or dirty conditions) replace the element.
1. Unfasten the air cleaner cover retaining knob and
remove the air cleaner cover (See Figure 23).
2. Remove the foam precleaner by sliding it up off the
paper element (See Figure 23).
3. Remove the wing nut and element cover plate,
then lift out the paper air filter element.
4. Do not wash the paper element or use pressurized
air, as this will damage the element. Replace a
dirty, bent or damaged element. Handle new
elements carefully; do not use if the sealing
surfaces are bent or damaged.
5. When servicing the air cleaner, check the air
cleaner base. Make sure it is secured and not bent
or damaged. Also check the element cover for
damage or improper fit. Replace all damaged air
cleaner components.
6. Inspect the rubber grommet (See Figure 23) for
deterioration, cracks, and for a snug fit on the air
cleaner stud. Replace if damaged or worn.
7. Reinstall the paper element, foam precleaner,
element cover, wing nut and air cleaner cover.
Make certain the cover retaining knob is tightened
securely.
Properly cleaned and installed air cleaner elements
significantly contribute to prolonging engine life.
CLEANING ENGINE
This tractor has an air-cooled engine. Air must be able
to circulate freely through the flywheel screen, blower
housing, and cooling shrouds, and over the cooling fins
of the cylinder head and cylinder block. Regularly
check these areas for accumulated dirt and debris to
prevent engine overheating and possibly causing
extensive engine damage. Every 100 hours of
operation, remove the blower housing and cooling
shrouds to clean the cooling surfaces of the engine.
Make sure the cooling shrouds are reinstalled.
Regularly clean the outside and inside of the side
panel screens, the dash intake screen and the grille to
ensure adequate air flow for cooling the engine.
NOTE
This machine is designed to cool properly with
the side panels in place. Operating without the
panels could cause premature accumulation of
dirt and debris on the engine, resulting in
inadequate cooling.
