How to use the undercarriage washer

From assembly to putting it away, step by step.

1

Get the 4 parts ready

First, check that you have all 4 parts: the main body, two extension pipes A, and extension pipe B (the 90-degree elbow).

  • Checking for missing parts first makes assembly easier.
  • Also give the connectors a quick look for anything unusual.

Slide it under the car and wash

Once assembled and connected, slide it under the car and wash the underside. Do not force it in — watch the vehicle and your surroundings.

  • Watch your footing and where the hose is.
  • Move it along the underside within a comfortable range.
