Question about Karcher 2500 PSI Pressure Washer
Not sure why but my psi washer all of the sudden started to have high psi come out of the syphon tube. When I pull the handle or nozzle back for low psi and pull trigger the tube will then start to **** up. Also seems like I do not have alot of high psi when nozzle switched to high?????
Hi - You're not trying to use the gun safety lock to keep the trigger on are you? I know how it sounds but I have to ask. This feature is just meant to act as a safety so that the trigger can not be accidentaly engaged. You are supposed to lose pressure when you let go of the trigger.

Go to www.karcher.com ,click on your region and then click international. Enter the model of the machine or the type number . That is is the first 8 digits of the number under the barcode. This will take you to the parts listing for your machine.

You most likely need to set your valve clearances. If it is hard to
pull over or the recoil snaps back after starting your valves need to
be set for sure. This may not be the entire problem but it is a good
start. Also change the spark plug, a bad plug will cause odd problems
and is too cheap not to eliminate as a source. In addition check your
fuel, pour a little out into a white container (I like spray paint can
caps for this) and look at the color. If it is yellow to orange it is
bad. You can pour it into you car, the car electronic sensors will
compinsate for it quality but a small engine can't. Use a NGK BP6ES or
10mm open end wrench
14mm open end wrench
1 long shaft screw driver or rod
1 spark plug socket and ratchet
Remove the spark plug and the valve cover. Pull the recoil over slowly until the intake valve opens (intake is closes to the carb and it will go down when it opens). Now put your long screwdrive down the spark plug hole. Slow pull the engine over until the screwdriver handle is at it highest point, this is top dead center. It may take a few attempts. Now check your valve clearance between the rockers and the top of the valve. The intake should be .006 and the exhaust .008, both can be +/- .001. To adjust: hold the large nut with the 14mm then loosen the small one with the 10mm. Lefty loosey. Now turn your large nut until you get the correct setting and then tighten the small one the lock it in. It may take a few attempts and alway reverify your setting after you lock it down. Once done, find top dead center again and reverify. Now your valves are set.

SOURCE: How can I start the
If there is a check valve in the little line that you put into your soap tank, it doesn't need primed. I have very large 5000 psi units and have enough suction without one. If you can't get it going, you can always remove the hose end near the pressure washer end and fill it by immersing the tubing in the soap, but that shouldn't be necessary. Sometimes the little fitting with the check valve in the bottom get plugged up as well, so that might be your problem. Hope this helps you, Rick
