Maintaining your pressure washer by having it periodically tuned, regularly checked and changing the pump oil are important for continued performance and equipment longevity. Allowing oil levels to get too low will increase the potential for damage and cause the pressure washer pump to overheat. Dirty oil, or oil that is contaminated with water will also cause problems. Hotsy recommends that pump oil be changed after the first fifty hours of operation and then every three months or 300 hours thereafter. The Hotsy oil offered here is a
10W-40 Non-Detergent Pump Oil specifically designed for use in Hotsy equipment but will provide protection for just about any brand of pressure washer.
