FUEL CAP, TANK, AND LINES
WARNING:
Check for fuel leaks. A leaking fuel cap, tank, or lines
are a fire hazard and must be replaced immediately. If
you find any leaks, correct the problem before using the
product. Failure to do so could result in a fire that could
cause serious personal injury.
The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel filter will cause poor engine per-
formance. If performance improves when the fuel cap is
loosened, the check valve may be faulty or filter clogged.
Replace the fuel cap if required.
SPARK PLUG REPLACEMENT
The spark plug for this engine may be replaced using a Ryobi
accessory spark plug or a Champion RCJ6Y. The spark plug
gap should be set at .025 in. Use an exact replacement and
replace annually.
NOTICE:
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.
