CLEAN AIR SCREEN
Air screen must be kept free of dirt and
chaff to prevent engine damage from
overheating. Clean with a wire brush or
compressed air to remove dirt and
stubborn dried gum fibers.
CLEAN AIR INTAKE/COOLING
AREAS
To insure proper cooling, make sure the
grass screen, cooling fins, and other
external surfaces of the engine are kept
clean at all times.
Every 100 hours of operation (more often
under extremely dusty, dirty conditions),
remove the blower housing and other
cooling shrouds. Clean the cooling fins
and external surfaces as necessary.
Make sure the cooling shrouds are
reinstalled.
NOTE: Operating the engine with a
blocked grass screen, dirty or plugged
cooling fins, and/or cooling shrouds
removed will cause engine damage due
to overheating.
AIR FILTER
Your engine will not run properly using a
dirty airfilter. Clean the foam pre-
cleaner after every 25 hours of operation
or every season. Service paper car-
tridge every 100 hours of operation or
every season, whichever occurs first.
Service air cleaner more often under
dusty conditions.

• Remove wing nut and air cleaner from
base.
TO SERVICE PRE-CLEANER
• Slide foam pre-cleaner off cartridge.
• Wash it in liquid detergent and water.
• Squeeze it dry in a clean cloth. Allow
it to dry,
• Saturate it in engine oil. Wrap it in
clean, absorbent cloth and squeeze to
remove excess oil.
TO SERVICE CARTRIDGE
• Replace a dirty, bent, or damaged
cartridge.
NOTE: Do not wash the paper cartridge
or use pressurized air, as this will
damage the cartridge.
• Reinstall the pre-cleaner (cleaned and
oiled) over the paper cartridge.
• Reassemble air cleaner, wing nut,
cover and tighten knob securely.
ENGINE OIL FILTER
Replace the engine oil filter every
season or every other oil change if the
tractor is used more than 100 hours in
one year.

section of this manual, through step

adapter.

tional 1/2 turn.

CHANGE ENGINE OIL" in this section
of this manual). For approximate
capacity see "PRODUCT SPECIFICA-
