4.Using oil funnel, slowly pour contents of provided oil bottle into oil fill opening to the "H" mark on dipstick. Be careful do not overfill. Overfilling with oil could cause the engine to not start or hard starting. ADD ENGINE OIL CAUTION NOTE: Degrees Celsiusº(Outside) 5.Replace oil fill cap/dipstick and fully tighten. 6.Oil level should be checked prior to each use or at least every 8 hours of operation. Keep oil level maintained.
ADD FUEL 1.Gasoline Fuel must meet these requirements: Clean, fresh, unleaded gasoline. Use regular UNLEADED gasoline with the generator engine with a minimum 87 octane / 87 AKI (91 RON). For high altitude use, see "Operation at High Altitude". Do not use gasoline with more than 10% alcohol such as E85 or ethanol. Avoid generator damage. Failure to follow Operator's Manual for fuel recommendations voids warranty. DO NOT use unapproved gasoline such as E85. DO NOT mix oil in gasoline.
• • • • • Attach the LPG regulator/hose assembly (included) to the LPG hose connector (inlet) on the control panel of the generator. Tighten the nut with 19 mm or adjustable wrench. Remove the safety plug or cap from the cylinder valve. Attach the other end of the LPG regulator/hose assembly to the cylinder valve. Tighten the nut by hand clockwise to a positive stop. Do not use a wrench to tighten. Use of wrench may damage quick closing coupling nut and result in a hazardous condition.
• In the event of an LPG fire, flames should not be extinguished unless by doing so the fuel supply valve can be turned off. If the fire is extinguished and a supply of fuel is not turned off, an explosion hazard greater than the fire hazard could be created. Keep a fire extinguisher near the generator all the time. Always keep the LPG cylinder in an upright position. Do not subject LPG cylinder to excessive heat. Contact with liquid contents of the cylinder will cause freeze burns to the skin.
Connecting to a Building's Electrical System Grounding The National Electric Code requires your generator must be properly connected to an appropriate ground to help prevent electric shock. WARNING Failure to properly ground the generator can result in electric shock. WARNING Generator voltage could cause electrical shock or burn resulting in death or serious injury. THERE IS A PERMANENT CONDUCTOR BETWEEN THE GENERATOR (STATOR WINDING) AND THE FRAME.

If you plan to run a portable electric generator during an outage, please notify your electric utility company immediately and remember to plug your appliances directly into the generator. Do not plug the generator into any electric outlet in your home. Doing so could create a connection to the utility company power lines.
If a cover is used, do not install until unit has cooled. for any unwanted shutdown. The generator cannot be started during or after the 4 minutes of FLASHING mode unless the fuel selector switch is turned to the "OFF" position and WARNING then turned back to the “GAS” or “LPG” position. NOTE: Disconnect the LPG cylinder from the generator during transportation.
NOTE: Observing frost on LPG cylinders and regulators is common during operation and normally is not an indication of a problem. As LPG vaporizes and travels from the tank to the generator engine it expands. The amount of frost that forms can be affected by the size of the cylinder, the amount of fuel being used, the humidity of the air and other operating conditions. In unusual situations this frost may eventually restrict the flow of LPG gas to the generator resulting in deteriorating performance.
