I had the same problem with my Karcher. The recall was lifted Aug. 0f 2007. Tried numerous people at Karcher....head of Customer Service, vice president, etc. No one returns telephone calls not even cutomer service....poor, very poor customer service. Thinking about calling Germany.

Try by entering in google KARCHER. Then find the home page. Find where to choose your country, and choose...INTERNATIONAL.
Then press MANUALS........then enter the model.
Now if you do not manage I give you some hints myself.
Always attach gun and water supply before switching on electricity. I advise that you start the machine without a lance first. See that when you close the gun the machine stops. If it does not stop, press quickly the gun again, and then switch off the electricity. If this happens you have a fault.
Now let us say the machine stops as it suppose to do, you can put on the lance. If you have a variable lance change from low to high by holding from the lance and not from the gun.
When you use chemical or detergent see that afterwards you rinse with pure water.
When you finish using machine, NEVER store with pressure in the system!!
Lubricate with silicon grease, connection of "gun hose" to machine.
Never use high pressure on car paint work or more important " not on car tyers"!!
Electricity and water do not go together. So inportant that you have a safety circuit breaker where to plug the machine.
If machine starts jerking when gun is closed or when gun is open, STOP instantly, and give to technician for servicing.
Never leave the machine on and with pressure when you are going somewhere. Always switch off and release pressure.

This problem, where the unit continually switches on and off when the handgun is closed, is quite common. Unfortunately it has at least six different possible causes, only two of which are easily checked.
The first thing you can do is look for leaks. Even the slightest leak will cause this pulsing because the unit gets up to pressure, switches off, loses pressure, switches back on again, comes back up to pressure, switches off... and so on. This repeated switching is not good for the motor and should not be allowed to continue for longer than necessary to observe what's happening.
So... 1. Does the handgun shut off completely, or does it drip? If it drips, it may simply be because a seal has failed. The handgun can be dismantled, checked, and any defective parts replaced; be sure to lubricate O-rings with silicone grease when reassembling. As a last resort, the whole gun may need to be replaced.
2. Are there any visible leaks at the high-pressure hose screw connections? If so, most likely an O-ring needs replacing - again lubricate the new one well with silicone grease.
3. If there are no visible leaks, either from the gun or from the connections, all other possible causes are internal within the cylinder head or control head of the pump. New parts will be needed and this normally calls for a professional repair, although it's not beyond the scope of a truly competent amateur.
I hope this helps. Any further questions, just ask! Please remember to rate this response.
