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.

AIR FILTER

Your engine will not run properly 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.

1. Loosen knob and remove cover.

TO SERVICE PRE-CLEANER
2. Slide foam pre-cleaner off cartridge.
3. Wash it in liquid detergent and water.
4. Squeeze it dry in a clean cloth. Allow it

to dry.

5. 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 car­

tridge.

NOTE:

Do not wash the paper cartridge

or use pressurized air, as this will damage
the cartridge.

2. Reinstall the pre-cleaner (cleaned and

oiled) over the paper cartridge.

proper position around stud. Replace if
necessary.

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 stub­

born dried gum fibers.

CLEAN AIR INTAKE/COOLING AREAS

To insure proper cooling, make sure the
grass screen, cooling fins, and other exter­

nal 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 cool­
ing 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.

MUFFLER

Inspect and replace corroded muffler and

spark arrester (if equipped) as it could cre­
ate a fire hazard and/or damage.

SPARK PLUG(S)

Replace spark plug(s) at the beginning
of each mowing season or after every
100 hours of operation, whichever occurs

first. Spark plug type and gap setting are

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 carbu­

retor, replacement is required.
1. With engine cool, remove filter and

plug fuel line sections.

2. Place new fuel filter in position in fuel

line with arrow pointing towards carbu­
retor.

3. Be sure there are no fuel line leaks and

clamps are properly positioned.

4. Immediately wipe up any spilled gaso­

line.

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 auto­

motive type wax.

We do not recommend using a garden

hose or pressure washer to clean your

tractor unless the engine and transmis­
sion are covered to keep water out. Water

in engine or transmission will shorten the
useful life of your tractor. Use compressed
air or a leaf blower to remove grass,
leaves and trash from tractor and mower.
