Dewalt DXGN4500 Instruction Manual - Page 12

OPERATION GENERAL INFORMATION This manual has been prepared to acquaint you with the operation and maintenance of this product. Study the information provided carefully to avoid problems associated with improper application or maintenance. Upon receipt of your generator, verify that it is complete and in good condition. The generator is comprised of a 4 stroke, air-cooled engine directly coupled to a 2 pole alternator producing either 125VAC or 125/250VAC depending on model. The no-load speed is approximately 3750rpm with the speed under load going to approximately 3600rpm thus producing a frequency of 60Hz. INITIAL INSPECTION Upon receiving your generator set, inspect the product to make sure it is complete and in good condition. Handle with care and place in a suitable site for storage or operation. GROUND CONNECTION The generator should be grounded to earth to reduce the risk of electrical shock. To do this you will need a grounding rod and an appropriately sized copper ground wire. Drive the ground rod into the earth, connect one end of the copper wire to the rod and connect the other end to the external ground connection on the generator set. This is a general explanation, consult National and Local electrical codes to ensure compliance. GENERATOR NEUTRAL BOND There is a permanent conductor between the generator (stator winding) and the frame. BEFORE START-UP ENGINE FUEL Use Unleaded Gasoline with minimum Octane 86. Check the fuel gauge and add as necessary. • SLOWLY ADD UNLEADED GASOLINE TO FUEL TANK • DO NOT OVERFILL TANK • DO NOT FILL ABOVE TOP OF FUEL SCREEN. THIS WILL ALLOW EXPANSION IN HOT WEATHER AND PREVENT OVERFLOW.

The battery is fully charged if a voltage of 13.7VDC is measured across the terminals using a DC Voltmeter. POSITIONING • Place the generator set on a flat and solid surface to prevent it from sinking. • Keep fuel, oil or other flammable or combustible materials at a safe distance from the generator set. • Select a site that is well ventilated and protected from the weather. • Place the generator set safely away from people and animals. TILTING CAN CAUSE FUEL SPILLAGE OPERATION Check the engine oil before each use. Never operate the generator set with insufficient oil. GENERATOR SET OVERLOAD ENGINE OIL The engine manual or other information provided by the engine manufacturer supersedes data provided here. Proper oil grade varies with climate. The grade listed in the table is typically a good grade but consult the engine manual to verify proper grade. The oil fill ports are located on both sides of the engine. The gray filler cap has an integral dipstick. Add the proper amount of oil and check the level using the dipstick. NOTE: The dipstick should be placed into the filler opening but not screwed in to check the level. Do not exceed the rated load of the generator set when operating continuously. Before connecting items to the generator set, determine the total electrical requirements of the products to be connected. The requirement of each item is generally given on the manufacturer's nameplate. Following is a list of commonly used items and typical requirements. Use this list as a guideline only if no other data is available. English 12 0068660
