CAUTION

If water freezes in the pressure washer, thaw it in a warm room before you try to start it. Do not pour hot water on or into the pump; it may crack the ceramic plungers!

DIf 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 it with a 50% antifreeze solution, and relieve the pressure. Flush the pressure washer before you use it again to remove the antifreeze.

DBefore you store the pressure washer overnight or transport it, disconnect the water supply, and turn off the fuel supply valve.

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

DPerform the appropriate maintenance. See Maintenance Chart at right.

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 you change the oil in these components following their respective break-in periods, the interval between required changes is longer.

If the pressure washer is operated in dusty conditions, these maintenance checks should be made more often.
