be replaced once each year.
CHECKING THE FUEL CAP
WARNING
A leaking fuel cap is a fire hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable filter and a
check valve. A clogged fuel filter causes poor engine
performance. If performance improves when the fuel cap
is loosened, the check valve may be faulty or the filter may
be clogged. Replace the fuel cap if necessary.

■ Loosen the spark plug by turning it counterclockwise
with a 5/8 in. socket. Remove the spark plug.
■ Hand thread the new spark plug. Turn it clockwise and
tighten with a socket. Do not overtighten.
WARNING
Do not cross-thread the spark plug. Cross threading
will seriously damage the product.
