Storage

Storage
1. Shut off unit and water supply.
2. Relieve system pressure by pointing gun away from
yourself and anyone else and squeezing trigger until
water flow ceases to exit nozzle.
3. Disconnect and drain hose, gun and wand.
4. Start unit and allow it to run until all water exits from
unit. Once water has stopped flowing from unit, turn
unit off.
5. Store hose, gun and wand with unit in a
non-freezing area.
If unit was stored in this manner, but exposed to
freezing temperatures, caution should be used as ice
chips can form from drops of water which could lead
to equipment damage. Allow unit to completely thaw
before starting.

Winterizing

For storage and transportation purposes in subfreezing
ambient temperatures, it will be necessary to winterize
the unit. The unit must be protected to the lowest
incurred temperature to prevent permanent damage.
The pumping system in this unit may be permanently
damaged if any part of the system becomes frozen.
Freeze damage is not covered by warranty.
If you must store the unit in an area where the
temperature falls below 32° F (0° C), perform the
following steps:
Do not operate unit in a freezing environment. Dam-
age to washer could occur.
Gather the following items:
• Two 5 gallon (18.9 liter) containers.
• One gallon (3.8 liter) of antifreeze.
• Water supply.

page 10.
3. Engage trigger lock and remove nozzle.
4. In one 5 gallon (18.9 liter) container, mix antifreeze
and water according to manufacturer's
recommendations for winterizing temperature.
NOTE: Proper winterizing is based on the
recommended manufacturer's instructions listed on
the Protections Chart shown on the back label of
most antifreeze containers.
5. Remove water supply hose from unit and attach 3 ft
hose securely to inlet connection. Submerge other
end into antifreeze solution.
6. Point wand into empty container and start unit.
