Question and Answers

Q:

power washer pump oil

A:

Thank you for your question and I understand your concern.

The engine and pump will require two different types of oil. The engine requires SAE 30 weight non detergent oil. Use the dip stick to measure the engine oil level.

The pump requires 4.057 ounces of 80w90 weight oil.

I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post.

Q:

not certain where spring on pressure washer goes

A:

Thank you for your question.

I will be happy to assist you. I searched in the service manual for an image of how the spring is connected. I could not find an image that showed it clearly. I found a picture of the spring on a model that I think is similar to yours. I posted the image below. Click on the image to enlarge it. If the image does not match yours, please post an image of the top of the carburetor on your model. Then I can try to find one that matches your model.

I hope this is helpful. Please let me know

Thank you for using Manage my life.

Q:

The power washer does not pull the cleaner from any of the storage tanks on high or low pressure and the water blows back into the storage tanks and flushes out

A:

Thank you for your question.

I am sorry you are having problems with the pressure washer. The fact that water is coming out of the injector tells me the steel ball in the injector is not moving and sealing. I recommend replacing the complete injector assembly. The steel ball stick it allows water to back flow into the chemical bottle. The injector is easy to replace it just unscrews. To prevent this from happening again use pump saver before storage. The pump saver will keep the pump from freezing and protects from rusting.

The part number for the injector is B3829GS. Please click on this link to order the injector .

If you have any other questions, please reply below with more details and I will get right back to you.
