Hi, I'm Mat from eSpares.

Now, if you've just purchased your Karcher, you haven't used it for a while, or you've recently replaced any parts, it's always a good idea to bleed the system to release any air left in there.

How you do this - connect your garden hose to the inlet cover, making sure the high pressure hose is detached from the front. Run the water through the system. Now do this for a minute or two just to make sure any air is gone. Now once that's done, reconnect your high pressure hose, like so, and you're ready to start pressure washing.
