How To Use A Digital Tachometer To Adjust Engine Speed On Your Pressure Washer

Описание: You must use a digital tachometer to properly adjust your pressure washer engine speed. This video shows how to attach a tachometer for a proper read, and how to use the tachometer to adjust your idle down cable.

Idle RPMs need to be measured with the engine running, water on, high pressure hose and wand hooked up, and the pump in bypass mode.

For the Dewalt Pressure Washer seen in this video, the unit needs to sit between 2600-2800 RPMs at Idle. Under load, it should be between 3400-3600 RPMs.
