Question and Answers

Q:

when i start my unit the pressure washer tries to shut off when i squezze to nozzle handle

A:

Thank you for your question.

I am sorry you are having a problem with your pressure washer. I had the same problem with my pressure washer when the temperature outside dropped. I found the problem was a combination of old gas and the wrong weight oil. Make sure the gas you are using is less than five weeks old. I also recommend using a fuel stabilizer in outdoor power equipment. It helps keep the gas from breaking down. Next, if the temp is below 50 degrees change the oil and use 5W30 synthetic. The synthetic oil can be use in temperatures of -22 to positive 104. Please make sure it is synthetic oil. if the engine still acts up under a load I suspect the problem is a dirty carburetor. When the passages of the carburetor plug up the engine will have a lack of power under a load. Cleaning the main jet with carb cleaner and bread tie wire usually cures the problem.

Please let me know if you need further assistance.

If you do not feel confident repairing this problem yourself, then you can have it repaired by a Sears technician. Here is a link that will provide the nearest drop-off locations: Sears Home Services .

Thank you for using Manage my life.

Q:

craftsman pressure washer has little pressure

A:

Thank you for your question.  I am sorry you are having a problem with the pressure washer. If you are not getting any pressure, I recommend cleaning the hole in the nozzle at the end of the wand. If it is plugged, it will hold the unloader valve open and the pump will not build pressure. If cleaning the nozzle does not help, I suspect the unloader valve is stuck open. Lime and minerals building in the pump cause this. You can try to remove the unloader and clean the parts to see if it helps. I posted an image below that show the parts of the unloader valve. Just click on the image to enlarge it. Once you have the unloader out use WD-40 and Scotch brite pad to clean the parts. After you have them clean, reassemble the unit and check the operation. If it still does not work, I recommend replacing the unloader. The parts for the pressure washer can be ordered from the following link.

Q:

craftsman power washer hose tail kit

A:

Hello David. The hose will normally need to be replaced on that pressure washer when it has leaks. According to your details, you may need to install an unloader kit to prevent the problem from occurring again. You can view the parts list diagram that has that unloader kit (and other kits for the pressure washer) on this page: Craftsman Pressure Washer Parts . Use the full model number of your pressure washer to view the parts for you particular model. If you need more help, reply with additional details and the full model number of your pressure washer.
