3.Perform the appropriate maintenance. See maintenance chart.

MAINTENANCE

Observing regular maintenance intervals helps ensure that you get maximum petformanceand life from the pressure washer.

There is a break-in period for the engine, pumpand gear reducer (if used). After changing theoil in these components following their respective break-in periods, the interval between required changes is longer.

If the unit Is operating in dusty conditions, these maintenance checks shouldbe made more often.

To reduce the risk of serious bodily injury, including fluid injection, splashingthe eyes or on the skin or injury from moving parts, always follow the PressureRelief ProcedureWarnlng before proceeding.
