For the purpose of this guide we're using a Hyundai HYW4000P, but most of these steps will still apply to the majority of domestic and commercial petrol pressure washers. This guide is meant to give you a quick overview of the process, however, and should not replace the information found in your product manual. If in doubt, always refer to your manual.

Attaching The Handles

To attach the handle, place it onto the handle supports which are connected to the main unit. Carefully align the handles with the holes and slide them in. Insert the carriage bolts through holes in the handle frame from the inside and attach the plastic knob on the outside. Tighten these by hands, and ensure they are tight and will not vibrate loose.
