Dewalt DXGN4500 Instruction Manual - Page 15

GENERAL STORAGE GUIDELINES GASOLINE FUEL FUMES ARE FLAMMABLE. DO NOT STORE YOUR GENSET IN ANY AREA THAT IS INDOOR OR IN POORLY VENTILATED AREAS. GASOLINE FUEL FUMES CAN IGNITE IN THE PRESENCE OF ANY OPEN FLAME, PILOT LIGHT, CLOTHES DRYER, WATER HEATER, ETC. Your generator should be started and operated for several minutes at least every 30 days. When the generator set is not being operated or is being stored more than one month, follow these instructions: 1. Replenish engine oil to upper level. 2. Run the generator, then close the fuel shut-off valve and allow the unit to run until the engine stops. 3. Move the engine switch to the "OFF" position. (Turn the key switch to "OFF" on the DXGN14000 model). 4. After the unit has cooled, drain gasoline from fuel tank, fuel line and carburetor. 5. Pour about one teaspoon of engine oil through the spark plug hole, pull the recoil starter several times and replace the plug. Then pull the starter until you feel the piston is on its compression stroke and leave it in that position. This closes both the intake and exhaust valves to prevent the inside of the cylinder from rusting. 6. Cover the unit and store in a clean, dry place that is well ventilated away from open flame or sparks. NOTICE: We recommend always using a fuel stabilizer. A fuel stabilizer will minimize the formulation of fuel gum deposits during storage. The fuel stabilizer can be added to the gasoline in the fuel tank, or into the gasoline in a storage container. GENERAL MAINTENANCE Proper maintenance and service are required to achieve maximum engine life and maintain warranty. The following tables provide engine specifications as well as maintenance schedules for the generator engines. Note that the generator models are referenced with the engine model. An engine owner's manual is provided with each machine that also provides basic maintenance and troubleshooting information. Defer to the engine manufacturers manual if any discrepancies appear between the data provided in this manual and the engine owner's manual. Full engine service manuals are available from American Honda Motor Co., 4900 Marconi Drive, Alpharetta, GA 30005-8847, (800) 910-1293.
