MAINTENANCE
IDLE SPEED ADJUSTMENT
See Figure 19.
WARNING:
The cutting head will move when adjusting the idle speed.
Wear all protective clothing and keep all bystanders,
children, and pets at least 50 ft. away. Make adjustments
with the unit supported by hand so that the blade/cutting
head does not contact the ground or any object. Keep
all parts of your body away from the cutting head and
muffler. Failure to follow these instructions could result
in serious personal injury.
If the cutting attachment turns at idle, the idle speed screw
needs adjusting on the engine. Turn the idle speed screw
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 20 - 21.
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:

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.
