Clean Air Screen; Spark Plugs; In-Line Fuel Filter; Cleaning - Craftsman 917.25023 Operator's Manual

CLEAN AIR SCREEN
The air screen is over the air intake blower
located on top of engine. The 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 stubborn dried gum fibers.
ENGINE COOLING SYSTEM
To ensure 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 cooling
shrouds. Clean the cooling fins and external
surfaces as necessary. Ensure 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 fue! filter should be replaced once
each season. If fuel filter becomes
clogged, obstructing fuel flow to carbure-
tor, replacement is required.
1. With engine cool, remove filter and
plug fuel line sections.
2. Place newfuel filter in position in fuel line
with arrow pointing towards carburetor.
3. Ensure there are no fuel line leaks and
clamps are properly positioned.
4. Immediately wipe up any spilled gaso-
line.

Except for the washout port (if equipped),
we do not recommend using a garden hose
or pressure washer to clean the outside of
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 outside tractor and mower.
