Air Filter; Spark Plugs; Engine Oil Filter; In-Line Fuel Filter - Craftsman EZ3 917.271014 Owner's Manual

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.
• Remove knob and cover.
• 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 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.
MUFFLER
Inspect and replace corroded muffler and
spark arrester (if equipped) as it could
create 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"
section of this manual.
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.
• Drain oil from engine crankcase (See
"TO CHANGE ENGINE OIL_'in this sec-
tion of this manual, through step re-
move drain plug).
• Remove oil filter and wipe off filter
adapter.
• Apply a thin coating of new engine oil to
the rubber gasket on replacement oil fil-
ter.
• Install replacement oil filter on filter
adapter. Turn oil filter clockwise until
rubber gasket contacts the filter adapter,
then tighten filter an additional 1/2 turn.
• Fill crankcase with new oil (See "7-0
CHANGE ENGINE OI1" in this section of
this manual). For approximate capacity
see "PRODUCT SPECIFICATIONS"
section of this manual.
• Start the engine and check for oil leaks.
Correct any leaks before placing en-
gine into full operation.
IN-LINE FUEL FILTER
Oil 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
clamps are properly positioned.
• Immediatly wipe up any spilled gaso-
line.
Filter
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.
