Regular maintenance will improve the performance and extend the life of the generator. See an authorized dealer for service.

The generator’s warranty does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain the generator as instructed in this manual and the engine operator’s manual.

NOTE: Should you have questions about replacing components on your generator, please call (877) 224-0458for assistance.

•Some adjustments will need to be made periodically to properly maintain your generator.

•All maintenance in this manual and the engine operator’s manual should be made at least once each season.

•Once a year you should clean or replace the spark plug, clean or replace the air filter. A new spark plug and clean air filter assure proper fuel-air mixture and help your engine run better and last longer. Please refer to your engine operator’s manual for more details.

Generator Maintenance

Generator maintenance consists of keeping the unit clean and dry. Operate and store the unit in a clean dry environment where it will not be exposed to excessive dust, dirt, moisture, or any corrosive vapors. Cooling air slots in the generator must not become clogged with snow, leaves, or any other foreign material.

NOTE: DO NOT use water or other liquids to clean generator. Liquids can enter engine fuel system, causing poor performance and/or failure to occur. In addition, if liquid enters generator through cooling air slots, some of the liquid will be retained in voids and cracks of the rotor and stator winding insulation. Liquid and dirt buildup on the generator internal windings will eventually decrease the insulation resistance of these windings.

Cleaning

Daily or before use, look around and underneath the generator for signs of oil or fuel leaks. Clean accumulated debris from inside and outside the generator. Keep the linkage, spring and other engine controls clean. Inspect cooling air slots and openings on generator. These openings must be kept clean and unobstructed.

Engine parts should be kept clean to reduce the risk of overheating and ignition of accumulated debris:

• Use a damp cloth to wipe exterior surfaces clean.

NOTICE

Improper treatment of generator can damage it and shorten its life.

•DO NOT expose generator to excessive moisture, dust, dirt, or corrosive vapors.

•DO NOT insert any objects through cooling slots.

•Use a soft bristle brush to loosen caked on dirt or oil.

•Use a vacuum cleaner to pick up loose dirt and debris.

Engine Maintenance

See the engine operator’s manual for instructions on how to properly maintain the engine.

CAUTION

Avoid prolonged or repeated skin contact with used motor oil.

•Used motor oil has been shown to cause skin cancer in certain laboratory animals.

•Thoroughly wash exposed areas with soap and water.

KEEP OUT OF REACH OF CHILDREN. DON’T POLLUTE. CONSERVE RESOURCES. RETURN USED OIL TO COLLECTION CENTERS.
