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.

• Reinstall the pre-cleaner (cleaned and

oiled) over the paper cartridge.

• Reassemble air cleaner, wing nut, cover

- and tighten knob securely.

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.

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.

Spark plug type and gap setting are

shown in “PRODUCT SPECIFICATIONS”
on page 5 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.

• Place new fuel filter in position in fuel

line with arrow pointing towards carbu­
retor.

• Be sure there are no fuel line leaks and

clam.ps are properly positioned.

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 carbu­

retor are covered to keep water out. Water

in engine can result in a shortened engine
life.
