Instructions for starting Huu Toan gasoline generators

1. Preparation before starting

Before starting the generator, you need to check all items below:

  • Check the lubricant level and fuel level. Your generator should have some sort of fuel gauge. Make sure that the generator's fuel tank is adequately filled before starting the machine. Add more of the appropriate fuel, if necessary. 
  • Disconnect the power transmission from the generator. Flip the circuit breaker off. Your generator will have a switch that controls when it puts out power. Make sure that it is safely in the “OFF” position.
  • Check the solution, battery voltage, connections to the battery. Note that the fight must be extreme. 
  • Check and fix any leaks on the generator. Check and tighten the bolt, screws, screws, wires, and electrical equipment. 
  • Open the fuel supply valve (if any).
  • Make sure the generator is placed in ventilated spaces, do not leave flammable substances near or on the generator.
