Spark Plug Maintenance; Replacing Wheels; Storing The Product - Ryobi RLM46175YL Instructions Manual

SPARK PLUG MAINTENANCE

See figure 12.
The spark plug must be properly gapped and free of
deposits in order to ensure proper engine operation. To
check:
Remove spark plug boot.
Clean any dirt from around base of spark plug.
Remove spark plug using a 13/16 in. spark plug socket
(not provided).
Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced.
NOTE: If replacing, use the following recommended
spark plugs or equivalent: E7RTC.
Measure plug gap. The correct gap is 0.71 mm
0.79 mm. To widen gap, if necessary, carefully bend
the ground (top) electrode. To lessen gap, gently tap
ground electrode on a hard surface.
Seat spark plug in position; thread in by hand to prevent
cross-threading.
Tighten with wrench to compress washer. If spark plug
is new, use 1/2 turn to compress washer appropriate
amount. If reusing old spark plug, use 1/8 to 1/4 turn for
proper washer compression.
NOTE: An improperly tightened spark plug will become
very hot and could damage the engine.
Reinstall spark plug boot.
DRIVE GEAR MAINTENANCE

To ensure smooth operation of wheels, the wheel assembly
should be cleaned before storage.

the drive shaft by wiping with a dry cloth. If necessary,
rubbing alcohol may be used to remove any stubborn
dirt.
CAUTION: Do not lubricate any of the wheel components
Lubrication may cause the wheel components to fail during
