Operation
Shutdown, Flushing and Storage
NOTE: An anti–freeze flush kit 802–327 is available to
make flushing easier.
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!
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.
2.
Before long-term (overnight) storage or transport-
ing of unit, disconnect the water supply, and turn
off the fuel supply valve.
3.
After each use, wipe all surfaces of the pressure
washer with a clean, damp cloth.
4.
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.
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 on page 5 before
proceeding.
