Ryobi RY28060 Cleaning the Exhaust Port and Muffler Spark Arrestor, Idle Speed Adjustment

MAINTENANCE

CLEANING THE EXHAUST PORT AND MUFFLER

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.

SPARK ARRESTOR

The spark arrestor must be cleaned or replaced every 50 hours or yearly to ensure proper performance of your prod- uct. 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 28.

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 may result from the cutting attachment turning at idle.

CLEANING AIR FILTER SCREEN

See Figures 29 - 30.

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

Remove the air filter cover by pushing down on the latch with your thumb while gently pulling on the cover.

Brush the air filter screen lightly to clean.

Replace the air filter cover by inserting the tabs on the bottom of the cover into the slots on the air filter base; push the cover up until it latches securely in place.

FUEL CAP

WARNING:

Check for fuel leaks. A leaking fuel cap 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 perfor- mance. If performance improves when the fuel cap is loos- ened, check valve may be faulty or filter clogged. Replace fuel cap if required.

SPARK PLUG REPLACEMENT

This engine uses a Champion RCJ-6Y or NGK BPMR7A spark plug with .025 in. electrode gap. Use an exact re- placement and replace annually.

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, spark plug fouling, hard start- ing, and increased emissions. Carburetor adjustment by an authorized service center will improve performance and allow that this engine meets EPA (Environmental Protection Agency) and California ARB (Air Resources Board) emis- sion standards. 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.
