CLEANING THE EXHAUST PORT, MUFFLER,
AND SPARK ARRESTOR
NOTICE:
The spark arrestor on this product has not been evaluated
by the USDA Forest Service and cannot be used on U.S.
forest lands. In addition, product users must comply
with Federal, State, and local fire prevention regulations.
Check with appropriate authorities. Contact customer
service or a qualified service center to purchase a
replacement spark arrestor.
NOTE: Depending on the type of fuel used, the type and
amount of lubricant used, and/or your operating conditions,
the exhaust port, muffler, and/or spark arrestor screen
may become blocked with carbon deposits. If you notice
a power loss with your gas powered tool, you may need to
remove these deposits to restore performance. We highly
recommend that only qualified service technicians perform
this service.
The spark arrestor must be cleaned or replaced every
50 hours or yearly to ensure proper performance of your
product. Spark arrestors may be in different locations
depending on the model purchased. Please contact your
nearest service dealer for the location of the spark arrestor
for your model.

IDLE SPEED ADJUSTMENT

See Figure 23.
WARNING:
The blade/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
blade/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
cutting 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.
MAINTENANCE
CLEANING THE AIR FILTER
See Figures 24 - 25.
For proper performance and long life, keep air filter clean.
 Remove the air filter cover by pushing down on the latch
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 slot on the air
filter cover over the latch on the housing, then push the
cover down until it snaps securely in place.
FUEL CAP, TANK, AND LINES
Check for fuel leaks. A leaking fuel cap, tank, or line is 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
performance. 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 AC00160, Torch L7RTC, or equivalent. The spark
plug gap should be set at .025 in. Use a recommended or
equivalent 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.
