Frequently Asked Questions

The oil sight gauge provides a visual window into the pump crankcase, allowing operators to quickly confirm that the oil level is within the proper operating range.

It is installed on the side of the pump crankcase. The location is designed so the oil level appears centered in the sight window when the pump contains the correct amount of lubricant.

Maintaining the proper oil level helps lubricate internal pump components, reduce friction, prevent overheating, and extend the lifespan of the pump.

The oil level should be inspected regularly during routine maintenance or before operating the pressure washer to ensure the pump remains properly lubricated.
