6. Reinstall the paper element, foam precleaner,
cover plate and knob. Reinstall the air cleaner
cover and reattach the cover clips to both sides of
the air cleaner body.

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 (See
Figure 26). 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, 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.
Figure 26
To assure smooth operation, keep the governor
linkage, springs and controls free of debris (See Figure
27).

CAUTION
Keep the muffler area clean. Before running the
engine, clean the muffler area to remove all
combustible debris. Inspect the muffler area often
when mowing during the Fall season
