How to operate a Mi-T-M power washer. Pressure washing tips.

What happens here

The presenter guides through the engine controls of the Honda GX 390 power washer. He identifies the pull rope for starting the engine. The gas on/off valve is located on the right; all the way to the right allows gasoline flow (on), and all the way to the left shuts it off. He instructs to leave it on during operation. The gray switch is the choke; right for 'run' (warm engine), left for 'choke' (cold engine). For a warm day, the choke is left in the run position. The throttle is all the way to the left for full throttle, or can be moved right to idle. He states that for this work, the throttle should always be at full.

Goal: Familiarize with engine startup controls and pressure settings.

Tools and materials

  • Choke Switch — Assisting engine startup in cold conditions
  • Gas On/Off Valve — Controlling fuel flow to the engine
  • Power Washer — The primary machine to be operated
  • Pressure Control Valve — Adjusting the output pressure of the pump (from 3000 PSI down)
  • Pull Rope — Starting the engine
  • Throttle — Adjusting engine speed

What they say

washer here, we've got um the pull rope. This actually starts the engine. We've got a gas onoff valve right here. And all the way to the right is allowing the engine to have gasoline. When you're done at the end of the day and you want to shut off the gasoline so the engine won't get no gas, you just flip it all the way to the left. We're going to have it all the way to the right. That's on. The gray um switch right here is the choke. All the way to the right is in the run position if it's warm. All the way to the left is choke. If it's really cold outside, you need to choke it to start it. Today's a warm day, so we don't need to choke it. This is the gas. Full throttles all the way to the left. If you just want it to idle, you can move it to the right. We're going to move it all the way to the left. We always keep it the left. At full throttle, we never change that. We actually never change the gas. We always keep it on. We always keep the engine at full throttle. Then on Honda engines, they all have an onoff switch. You want to make sure it's on in the on position.
