Page 9 Use high-detergent, premium quality 4 –stroke engine oil, certified to meet or exceed U.S. automobile manufacturer’s requirements for API Service Classification SG. SF.(15W40) Select the appropriate viscosity for the average temperature in your area. Ambient Temperature Loosen the cover screw and remove the left side maintenance cover. Remove the oil filer cap, and wipe the dipstick with a clean rag.
Page 10 4.2 Check the fuel level Turn the fuel cap lever to “OFF” position before transporting. Use automotive fuel (Unleaded or low leaded is preferred to minimize combustion chamber deposits). !! Don’t use fuel-containing alcohol: Fuel system damage or engine performance problems resulting from the use of fuels that contain alcohol are not covered under the warranty.

Page 13 6. After the engine starts, allow the engine to run continuously and warm up. 7. Press the choke in completely after the engine is started. If the engine stops and will not restart, check the engine oil level before troubleshooting in other areas. Move to the right to deactivate Before using the device once it is connected, switch off the ECO switch.
Page 14 5.3 Generator use 5.3.1 Warning! ■To prevent electrical shock from faulty appliances , the generator should be grounded. Connect an electric conductor (cable) of at least 1.5mm between the generator’s ground terminal and an external ground source. ■Connections for standby power to a building’s electrical system must be made by a qualified electrician and must comply with all applicable laws and electrical codes.
Page 15 5.5 Output and Overload indicators. The output indicator light (green) will remain lighted during normal operating conditions. If the generator is overloaded or of here is a short in the connected appliance, the output indicator light (green) will go OFF, the overload indicator light (red) will go ON and current to the connected appliance will be shut off.
Page 16 When the output indicator light (green) does not light and the overload indicator light (red) lights instead, set the engine switch to STOP, stop the engine at once and then start the engine again. 3. Confirm that the equipment to be used is switched off, and insert the plug of the equipment to be used into the AC receptacle unit A.
