Hi there

Not sure if this is the correct part of the forum but here goes. I have a Karcher K4 pressure washer.

When removing one of the lances the other day the o-ring (the yellow thing that is normall in the bottom of the various lances) became stuck in the gun - meaning I can't change attachments etc.

Does anyone have any ideas or tricks as to how to remove it, it seems fairly well stuck, without mucking everything else up.

The Karcher website is pretty useless in terms of support

You might be able to use sufficiently sized screw to pull it out. Wind the screw in and then pull the screw and fitting out.

The following shows you how to put the yellow plug back in.

Whenever I finish using my pressure washer I turn it off, turn off the water supply and then release the pressure in the system by releasing the trigger before removing the lance and hose.
