tridge.

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.
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.
o Drain oil from engine crankcase (See
'%0 CHANGE ENGINE OIL" in this sec-
tion of this manual, through step remove
drain plug)o
° Remove oil filter and wipe off filter
adapter.
o Apply a thin coating of new engine oil to
the rubber gasket on replacement oil fil-
ter.

adapter. Turn oil filter clockwise until
rubber gasket contacts the filter

1/2 turn.

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

each mowing season or after every 100
hours of operation, whichever occurs first.

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.
o With engine cool, remove filter and plug
fuel line sections.
° Place new fuel filter in position in fuel
line with arrow pointing towards carbu-

CLEANING
° Clean engine, battery, seat, finish, etc.
of all foreign matter.
o 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.
