■ MONTHLY MAINTENANCE
FUEL FILTER
When the engine runs short of fuel supply, check
the fuel filter for blockage. (MA9)
OIL STRAINER
Drain the oil tank and remove the oil strainer
located near the spark plug. Check the condition
and clean if necessary. (MA10)
SPARK PLUG
Starting failure and mis-firing are often caused by a
fouled spark plug. Periodically clean the spark plug
and check that the spark gap is in the correct
range. (MA11)
For a replacement plug, use Champion RCJ-
6Y(noise-proof) or CJ-6Y, or NGK BPMR7A.
DRIVE SPROCKET
Periodically check the drive sprocket for wear and
damage, and replace when the teeth have worn
over 0.04 inch, or when any damage has been
observed. (MA12)
HANDLE MOUNTING JOINTS
Inspect the handle mounting joints and replace
when any adhered part is peeled off or a crack is
observed on the rubber part. Also replace when the
inside of the rear damper metal has worn
remarkably.
