Checking The Fuel Cap; Storing The Product - Ryobi RBC254FSDSN Operator's Manual

this manual. For other repairs, have the trimmer serviced
by an authorised service dealer.
CLEANING THE AIR FILTER (FIG. 11)
A dirty air filter will cause starting difficulty, loss of
performance, and shorten the life span of the engine.
Check the air filter monthly. For best performance, replace
the air filter at least once a year.
■ Loosen the air filter cover by turning the cover securing
knob (item 22) counterclockwise.
■ Remove the air filter (item 20).
■ Clean the foam filter element with warm soapy water.
Rinse and let dry.
NOTE: If the foam filter element is damaged, it should be
replaced.
■ Apply a light coat of engine oil to the foam filter
element, then squeeze it out.
■ Reinstall the air filter.
NOTE: Make sure the filter is seated properly inside the
cover. Installing the filter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
■ Reinstall the cover and tighten knob to secure.

CHECKING THE FUEL CAP

A leaking fuel cap is a fire hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable filter and
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.
REPLACING THE SPARK PLUG (FIG. 12)
This engine uses a Champion RCJ4 / RCJ6Y or NGK
BPMR7A spark plug. Use an exact replacement and
replace annually.
Follow these steps to replace the spark plug.
■ Remove the spark plug boot (item 25).
■ Loosen the spark plug (item 26) by turning it
counterclockwise with a 19 mm socket.
■ Remove the spark plug.
■ Hand thread the new spark plug, turning it clockwise.
■ Tighten with a socket. Do not overtighten.
WARNING
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the engine.
CLEANING THE SPARK ARRESTOR (FIG. 13)
