MAINTENANCE
1.
Remove spark plug and check
for fouling, worn and rounded
center electrode.
2.
Clean the plug or replace with a
new one. DO NOT sand blast to
clean. Remaining sand will
damage engine.
3.
Adjust spark plug gap by
bending outer electrode.
4.
Tighten spark plug to 102-153 kgf • cm (86-133 in • lbf).
Cooling System
Level 2.
To maintain proper engine operating temperatures, cooling air must
pass freely through the cylinder fin area. This flow of air carries
combustion heat away from the engine.
Overheating and engine seizure can
occur when:
• Air intakes are blocked,
preventing cooling air from
reaching the cylinder.
• Dust and grass build up on the
outside of the cylinder. This build
up insulates the engine and
prevents the heat from leaving.
Removal of cooling passage
blockages or cleaning of cooling fins
is considered "Normal
Maintenance." Any failure attributed
to lack of maintenance is not warranted.
Cleaning Grill
1.
Brush accumulated debris from intake grill between backpack frame
and blower housing.
