Maintenance

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

There is a break–in period for the engine and pump. After changing the oil 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 should be made more often.

WARNING

To reduce risk of serious bodily injury, including fluid injection, splashing in eyes or on skin or injury from moving parts, always follow Pressure Relief Procedure on page 6 before proceeding.
