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 re­
moved will cause engine damage due to
overheating.
AIR FILTER
Your engine will not run property using a
dirty air filter. Clean the foam pre-cleaner
after every 25 hours of operation or every
season. Service paper cartridge every
100 hours of operation or every season,
whichever occurs first.
Service air cleaner more often under dusty
conditions.
• Loosen knob and remove cover.
TO SERVICE PRE-CLEANER

• Wash it in liquid detergent and water.

to dry.
• Saturate it in engine oil. Wrap it in
clean, absorbent cloth and squeeze to
remove excess oil.

ENGINE OIL FILTER
Replace the engine oil filter every season
or with every second oil change if the trac­
tor is used more than 100 hours in one
year.
MUFFLER
Inspect and replace corroded muffler and
spark arrester (if equipped) as it could cre­
ate a fire hazard and/or damage.
SPARK PLUGS
Replace spark plugs at the beginning of
each mowing season or after every 100
hours of operation, whichever occurs first.

shown in “PRODUCT SPECIFICATIONS"
section of this manual.
IN-LINE FUEL FILTER
The fuel filter should be replaced once
each season. If fuel filter becomes
clogged, obstructing fuel flow to carbure­
tor, replacement is required.
• With engine cool, remove filter and plug
fuel line sections.

line with arrow pointing towards carbu­
retor.

CLEANING
• Clean engine, battery, seat, finish, etc.
of all foreign matter.
• Keep finished surfaces and wheels free
of all gasoline, oil, etc.
• Protect painted surfaces with automo­
tive type wax.
We do not recommend using a garden
hose to clean your tractor unless the elec­
trical system, muffler, air filter and carbure­
tor are covered to keep water out. Water
in engine can result in a shortened engine
life.
