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 automotive 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.
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 removed
will cause engine damage due to overheating.
AIR FILTER (See Fig. 15)
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 cartridge.
NOTE: Do not wash the paper cartridge or use pressurized
air, as this will damage the cartridge.
•
