    When replacing the Pressure Washer Outlet Connection Cover on your Karcher K4.99 pressure washer the O ring seal is a vital part of the change. After a few years the original O ring will have deteriorated and you cannot guarantee a good seal unless you replace it at the same time. Otherwise you may find yourself dismantling the unit to fit one at a later date which doubles to the work.

  • Q How does the 'O' ring actually fit? 1 Answer

    There does not seem to be an obvious groove for the @o@ ring to fit into. I messed the current one by it going into the locking slot. Do you have a diagram that shows its position. Your video doesn't really help as it doesn't show the 'O'ring in place or how to refit the assembly.

  • Q loss of water pressure 1 Answer

    I have a Karcher 310. Yesterday the motor made a small "pop" sound and the water pressure dropped, and water started coming thro the vents in the back of the machine (and still thro the lance). Could you please advise what the problem is and what part I will need to hopefully fix this problem. The motor is still working.

      Hi Deckie, I'm going to refer you to the instruction manual for your model, which can be viewed here: http://www.espares.co.uk/datastore/ProductManuals/561741.pdf If you go to page 18 of the document, it has a troubleshooting guide with ways you can diagnose the cause of your problem.
