whenever you stop spraying for more than 10
minutes, when shutting down, and before
checking or repairing any part of the system.

2. Turn the sprayer off.
3. Remove the ignition cable from the spark
plug.

6. Before long–term (overnight) storage or
transporting of unit, disconnect the water

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.
NOTE:
An anti–freeze flush kit, P/N 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!
2. After each use, wipe all surfaces of the pressure
washer with a clean, damp cloth.
3. Perform the appropriate maintenance. See
maintenance 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
maintenance checks should be made more often.
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
