Craftsman 917.2720601 - Manual (Page 22)

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
removed will cause engine damage due
to overheating.
MUFFLER
Inspect and replace corroded muffler and
spark arrester (if equipped) as it could
create 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.
CLEAN AIR INTAKE/COOLING AREAS
The fuel 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.
Place new fuel filter in position in fuel
line with arrow pointing towards
carburetor.
Be sure there are no fuel line leaks
and clamps are properly positioned,
immediately wipe up any spilled
gasoline.

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
electrical system, muffler, air filter and
carburetor are covered to keep water out.
Water in engine can result in a shortened
engine life.
