Servicing the Paper Element
Every 100 hours of operation (more often under
extremely dusty or dirty conditions), inspect the paper
element. Replace the element as necessary.
1. Unfasten the air cleaner cover retaining knob and
remove the air cleaner cover (See Figure 24).
2. Remove the foam precleaner by sliding it up off the
paper element (See Figure 24).
CAUTION
The air cleaner element cover plate (See Figure
24) must be properly installed to seal against
the gasket surface of the paper element.
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 seal (See Figure 24)
for deterioration, cracks, and for a snug fit on the
carriage bolt. Replace if damaged or worn.
7. After making certain the carriage bolt is secured in
position by the retaining ring, slide the grommet
seal fully onto carriage bolt. See Figure 24.
8. Install the cover plate on the carriage bolt and
secure with the wing nut. Do not overtighten the
wing nut, which could deform the cover plate.
9. Reinstall the 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 around the engine through the
flywheel screen, through the cooling shrouds and over
the fins of the cylinder head and cylinder block. Keep
these areas free of accumulated dirt and debris or the
engine will overheat; possibly causing extensive
engine damage. Regularly clean the inside of the side
panels, dash intake screen and grille to ensure
adequate cooling. If debris has accumulated inside the
cooling shrouds of the engine, the blower housing and
cooling shrouds should be removed and the cooling
fins cleaned.
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.
SPARK PLUG
WARNING
To avoid possible injury, be sure the engine is
off and has cooled before making any
adjustments or repairs.
NOTE
Remove all dirt from around the spark plug
before removing.
To remove the spark plugs, always use a spark plug
wrench. Check the gap after every 100 hours of
operation.
