Having problems with your Pressure Washers ?

When motor is at idle speed it surges

\015 When motor is running at idle speed it surges up and down but when i pull the trigger on the wand it runs smooth\015

Answers :

Try a simple test. It is ok to run the pump without water for a short time. Check idle speed without water in system to see if enginet surges. If it does not surge, then most likely the unloader/ pressure valve is causing the engine to surge when in the unloaded state. Life of unloader /pressure valve is shortened by letting system bypass for long periods of time. Enjoy
