GENERATOR PREPARATION The following section describes the necessary steps to prepare the generator for use. If you are unsure about how to perform any of the steps please call (800) 232-1195 M-F 8-5 CST for customer service. Failure to perform these steps properly can damage the generator or shorten its life. STEP 1 - ADD OIL The generator is shipped without oil. User must add the proper amount of oil before operating the generator for the first time. The oil capacity of the engine crankcase is 13.5 fl.
GENERATOR PREPARATION STEP 2 - ADD GASOLINE GASOLINE WARNING: Keep generator away from open flame. This generator may emit highly flammable and explosive gasoline vapors, which can cause severe burns or even death if ignited. A nearby open flame can lead to explosion even if not directly in contact with gasoline. • Do not operate near open flame. • Do not smoke near the generator. • Always operate on a firm, level surface. • Always turn generator off before refueling.
GENERATOR PREPARATION STEP 3 - GROUND THE GENERATOR To reduce the risk of electric shock and to maximize safety, the generator should be properly grounded. Ground the generator by tightening the grounding nut on the front control panel (Fig. 5) against a grounding wire. A generally acceptable grounding wire is a No. 12 AWG (American Wire Gauge) stranded copper wire. This grounding wire should be connected at the other end to a copper, brass, or steel-grounding rod that is driven into the earth.
STARTING THE GENERATOR DANGER: CARBON MONOXIDE Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO). This is a poison gas you cannot see or smell. If you can smell the generator exhaust, you are breathing CO. But even if you cannot smell the exhaust, you could be breathing CO. NEVER use a generator inside homes, garages, crawl spaces, or other partially enclosed areas. Deadly levels of carbon monoxide can build up in these areas.
STARTING YOUR GENERATOR Before starting the generator, make sure you have read and performed the steps in the “Generator Preparation” section of this manual. If you are unsure about how to perform any of the steps in this manual please call (800) 232-1195 M-F 8-5 CST for customer service. 1. Place the generator outside on a dry, level surface. Allow at least two feet of clearance on all sides of the generator. 2. No electrical devices should be connected to the generator during startup.
USING THE GENERATOR CALCULATING THE WATTAGE OF YOUR DEVICE(S) Connect electrical devices running on AC current according to their wattage requirements. Calculate the running wattage and starting wattage of the device(s) you wish to connect, and MAKE SURE that they are within the capacity of your generator.
USING THE GENERATOR The chart below serves as a reference for the estimated wattage requirements of common electrical devices. However, do not solely rely on this chart - all electronics and appliances are built differently. Always check the wattage listed on the electrical device before consulting this chart.
USING THE GENERATOR IN CASE OF OVERLOAD If your generator becomes overloaded from too much drawn wattage, the circuit breaker(s) on your control panel will pop out and cut off power in order to protect the generator. When an overload occurs, disconnect all electrical devices from the generator and wait five minutes, then press the circuit breaker to reset. Check the total wattage of the devices, and reduce the load if it exceeds the capacity of the generator.
STOPPING THE GENERATOR CAUTION: Unplugging running devices can cause damage to the generator. Never stop the engine with electrical devices connected and running. To shut off the generator: 1. Turn off all electrical devices prior to unplugging them from the generator. Unplugging running devices can cause damage to the generator. 2. Push the engine switch to the OFF position. 3.
