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.
