CAUTION

If water does freeze in the pressure washer 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!

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.

Before long-term (overnight) storage or transport ing of unit, disconnect the water supply of

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

Perform the appropriate maintenance. See mainte nance chart.

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, pump and gear reducer (if used). 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 main tenance checks should be made more often.
