  1. The generator comes with an engine switch on the control panel that controls the ignition system and fuel and choke valves.
  2. It features an electric starter feature on the control panel with an On and Off function.
  3. The On setting starts the engine while the Off button closes the fuel valve to stop the engine.

Once you understand these basics, here are the items you will need for a successful setup

  1. A clean gasoline can
  2. Fresh gasoline or fuel. According to the manufacturer, it is best to avoid using any oil with more than 10% ethanol
  3. 1 Qt. of SAE 10W-30 oil
  4. A small funnel
  5. A 10-millimeter socket and ratchet
  6. Clean cloth to wipe spills
  7. The user manual.

Before proceeding, ensure you have placed your generator in a safe spot. While all Honda generators are tested and cleared before shipping, it is best to observe all safety features like not having a child operate the generator.

When ready to start the setup process, follow these steps;

  1. Open the generator's oil maintenance cover and remove the dipstick.
  2. Using the small funnel, pour in oil slowly until it starts to spill. Reinstall the dipstick and use the cloth to wipe any oil on the surface before closing the maintenance cover.
