WARNING
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including
fluid injection and splashing in the eyes, or on the
skin, always follow this procedure whenever you
stop spraying for more than
shutting down, and before checking or repairing
any part of the system.
1. Engage the trigger safety latch.
2. Turn the sprayer off.
3. Remove the ignition cable from the spark plug.
4. Shut off the water supply.
5. Disengage the trigger safety latch and trigger
the gun to relieve pressure, and then engage
the trigger safety latch again.
6. Before long–term (overnight) storage or
transporting of unit, disconnect the water
supply, and turn off the fuel supply valve.
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 Pressure Relief Procedure Warning
before proceeding.
