This sounds like the bypass (unloader) valve is sticking. Here is a diagram of your machine's pump. On page 2.4 see part #1. The top of this assembly is a black plastic cover. Remove all of assembly # 1 carefully. Under that is part #8. This is the bypass valve. You need to pull this out, check that the o-rings are not bent, worn or damaged, then lube it good with a VERY VERY good waterproof grease. Re-assemble it and all should be well. The part numbers are on the diagram but where to get them depends on were you live. Karcher web site may give you a number to call. Good luck.

Have a helper hold the trigger of the wand open while you try it again. If it starts that way you have a sticky unloader valve in the pump. DO NOT RELEASE the trigger for more than 10 seconds if the engine continues to strain when released! If the engine doesnt run freely when you let go of the trigger, pull it again and shut down the unit!
Add some power steering fluid to your supply hose (about 3 or 4 ounces at a time) and restart the unit with the trigger pulled. Allow the oil to flow through the pump for 1 - 2 minutes for each treatment. Several treatments should make the pump and valve happy again.
Hope this helps.

SOURCE: Pulsating when idle
The motor doesn't pulsate when you are spraying and pulsattes when not spraying is normal otherwise the pressure will just keep building and burn out the pump. However, if you are not using the sprayer right away then the unit should be shut off until your ready to start again.
I hope the answer is helpful, please rate if the answer has helped in any way. Good Luck and have a great weekend.
