Ryobi RYi4022X Operation Manual - Page 20

OPERATION HIGH ALTITUDE OPERATION Your engine is configured for operation below altitudes of 2,000 feet for 099930628 and 095930628, or 3,000 feet for 099930627 at the factory. Your engine must be reconfigured for operation above the preconfigured altitude. Operating the engine with the wrong engine configuration at a given altitude may increase its emissions, decrease fuel efficiency, degrade performance, and cause irreversible damage. Engines configured for high altitude operation cannot be operated in standard altitude conditions. A qualified service center should ensure that your engine is properly configured for your location. MAINTENANCE Normal maintenance, replacement or repair of emission control devices and systems may be performed by any qualified repair establishment or individual with original or equivalent parts. Warranty and recall repairs must be performed by an authorized service center; please contact customer service for assistance. WARNING: Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to stop, and disconnect spark plug wire and move it away from spark plug. Allow 30 minutes of cool down time before performing any maintenance. Failure to follow these instructions can result in serious personal injury or property damage. WARNING: When servicing, use only recommended or equivalent replacement parts. Use of any other parts could create a hazard or cause product damage. WARNING: DO NOT tamper with, adjust, or modify the carbon monoxide (CO) sensor module on your generator. Failure to follow these instructions can cause the monitor to malfunction which can result in death or serious personal injury. NOTICE: Periodically inspect the entire product for damaged, missing, or loose parts such as screws, nuts, bolts, caps, etc. Tighten securely all fasteners and caps and do not operate this product until all missing or damaged parts are replaced. Please contact customer service or a qualifed service center for assistance. GENERAL MAINTENANCE Keep the generator in a clean and dry environment where it is not exposed to dust, dirt, moisture, or corrosive vapors. Do not allow the cooling air slots in the generator to become clogged with foreign material such as leaves, etc. Do not use a garden hose to clean the generator. Water entering the fuel system or other internal parts of the unit can cause problems that will decrease the life of the generator. To clean the unit: n Use a soft bristle brush and/or vacuum cleaner to loosen and remove dirt and debris. n Clean air vents with low pressure air that does not exceed 25 psi. n Wipe the exterior surfaces of the generator with a damp cloth. CHECKING/CLEANING AIR FILTER See Figures 12. For proper performance and long life, keep air filter clean.  Rotate knob counterclockwise to release. Remove cover and set aside.  Remove the filter element.  If the filter element is dirty, clean with warm, soapy water. Rinse and let dry.  Apply a light coat of engine lubricant to the element, then squeeze it out.  Replace the element in the air filter unit.  Replace the air filter cover and rotate knob clockwise to secure. NOTE: Make sure the filter is seated properly inside the generator. Installing the filter incorrectly will allow dirt to enter the engine, causing rapid engine wear. 16 - English
