OPERATION LIFTING THE GENERATOR See Figure 13.  Turn off the generator.  Fold the handle to the down position. Never lift or carry this product using the handle. NOTE: This tool is heavy and requires several people to lift. To avoid back injury, keep your knees bent and lift with your legs, not your back, and get help when needed. HIGH ALTITUDE OPERATION Your engine is configured for operation below 3,000 feet altitude at the factory. Your engine must be reconfigured for operation above 3,000 feet 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 can create a hazard or cause product damage. 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 qualified 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:  Use a soft bristle brush and/or vacuum cleaner to loosen and remove dirt and debris.  Clean air vents with low pressure air that does not exceed 25 psi.  Wipe the exterior surfaces of the generator with a damp cloth. CHECKING/CLEANING AIR FILTER See Figure 14. 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: Do not run the generator without the air filter. Rapid engine wear will result. CHANGING ENGINE LUBRICANT See Figure 15.  Remove the oil cap/dipstick.  Place a container underneath the oil drain plug to collect used lubricant as it drains.  Unscrew the oil drain plug and remove.  Allow lubricant to drain completely. NOTE: Drain the lubricant while the engine is still warm but not hot. Warm lubricant will drain quickly and more completely. Page 15 - English
