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 pump. After changing the oil initially, the interval between required changes is longer.

WARNING

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

1.If the pressure washer will be exposed to freezing temperatures, drain all water out of the pump. If it must be stored in freezing temperatures, flush the unit with a 50% anti–freeze solution. Relieve pressure. Flush the pressure washer before using it again to remove the anti–freeze.

CAUTION

If water does freeze in the pressure washer , thaw it in a warm room before trying to start it. DO NOT pour hot water on or into the pump; it may crack the ceramic plungers!

2.After each use, wipe all surfaces of the pressure washer with a clean, damp cloth.

3.Perform the appropriate maintenance. See the maintenance chart.
