CLEANING
Engine Air Cleaner System
There are two components in the engine air cleaner
system: a foam prefilter element and a paper ele-
ment. Each component is checked, cleaned and
maintained on a different schedule based on the fil-
tering action required. Each component is serviced
as follows:
Engine Air Cleaner Foam and Paper Element
Foam Precleaner Element
Clean and inspect the foam element after every 25
hours of service and replace the element yearly (or
when dirty or damaged). Wash the element in de-
tergent and water; and dry it thoroughly. More fre-
quent cleaning may be required when operating in
extremely dusty conditions.
Paper Precleaner Element
Inspect the paper element after every 50 hours of
service and replace the element every 200 hours
(or when dirty or damaged). More frequent replace-
ment may be required when operating in extremely
dusty conditions.
Be careful to reinstall the foam element and the pa-
per element into the air cleaner case. Carefully re-
install the air cleaner cover into the air cleaner body
by putting the hooks on the bottom of the air cleaner
cover into the air cleaner body bottom.
Engine Cooling System
Air Intake Screen
Before each use, check that the air intake (rotary)
screen is free from grass and debris and clean if
necessary.
Engine Cooling Fins
Every 100 hours, check and clean the cooling fins
and inside of engine shrouds to remove grass, chaff
or dirt clogging the cooling system and causing
overheating. When cleaning, remove the recoil
starter and the fan housing.
Grass Buildup in Mower Housing
1. Raise the deck lock lever handle on each side
of the carrier frame and pull out to release car-
rier frame for tilting action.
2. Using the carrier frame lift handle, raise deck to
the TILT-UP position and insert the deck hook
into the tilt-up latch on the tractor body.
3. Clean grass buildup underneath the deck using
a pressure washer (and scraper if required).
NOTE: While some degree of material buildup
in the mower deck housing can be tolerated, a
point is finally reached where cutting quality
deteriorates and clogging begins to occur
because of too much buildup on the baffling and
housing.
4. Lower the deck to the normal operating position
and reengage the deck lock levers.

DANGER
Before raising or removing the mower
deck for cleaning, stop the engine, re-
move the ignition key, and disconnect the
spark plug wires.
DANGER

up position. Do not move the tractor with
the deck in the tilt-up position.
CAUTION
NEVER operate the cutter blades with the
deck in the raised position.
