MAINTENANCE

counterclockwise to reduce the idle RPM and stop the cut-

ting attachment movement. If the cutting attachment still

moves at idle speed, contact a service dealer for adjustment

and discontinue use until the repair is made.

WARNING:

The cutting attachment should never turn at idle. Turn

the idle speed screw counterclockwise to reduce the

idle RPM and stop the cutting attachment, or contact a

service dealer for adjustment and discontinue use until

the repair is made. Serious personal injury could result

from the cutting attachment turning at idle.

CLEANING THE AIR FILTER

See Figures 26 - 27.

For proper performance and long life, keep air filter clean.

 Remove the air filter cover by pushing down on the latches

while gently pulling off the cover.

 Remove the air filter.

 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.

 Replace the air filter cover by placing the slots on the air

filter cover over the latches on the housing, then push

the cover down until it snaps securely in place.

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.

STORING THE PRODUCT

 Clean all foreign material from the product. Store idle unit

indoors in a dry, well-ventilated area that is inaccessible

to children. Keep away from corrosive agents such as

garden chemicals and de-icing salts.

 Abide by all ISO and local regulations for the safe storage

and handling of gasoline.

When storing 1 month or longer:

 Drain all fuel from tank into a container approved for

gasoline. Run engine until it stops.

HIGH ALTITUDE ENGINE OPERATION

Please have an authorized service center adjust this engine

if it is to be run above 2000 feet. Failure to do so may result

in poor engine performance and increased emissions. An

engine adjusted for high altitudes can not be run at 2000

feet or lower. In doing so, the engine will overheat and cause

serious engine damage. Please have an authorized service

center restore high altitude modified engines to the original

factory specification before operating below 2000 feet.
