Karcher K2 Compact Assembley

The Karcher K2 Compact is a very popular jet washer, so popular in fact you have seemingly just bought one and want to know how to assemble it. Well luckily for you I also bought one, and have taken step by step assembly photos to help you out!

Step 1 Screw on the hose adapter

If you are using the K2 Compact with a garden hose, which is what I guess most people will be doing, then you will need to screw this little adapter on first.

Step 3 Connecting the gun

Now you want to connect the gun to the actual jetwash. There will be a black hose that came with the jetwash with a connector on each end. These connectors are identical so you can’t get this the wrong way round.

One end connects into the gun and the other into the K2 compact.

The black hose connects to the washing machine here at the bottom where the grey tab is. To start with you need to push this grey tab upwards to open it.

Now we need to connect the other end of the pressure hose into the gun. The connection is at the bottom of the gun and works in the same way but with a yellow locking tab this time.

You can see the tabs above on the lance. These will only insert in one direction, with the tabs facing away from the hole in the bottom piece.

Rotate the lance so it looks like the below image with the little yellow mark lining up with the holes in the end of the gun.
