Between-Use Storage

Before storing, let machine cool for at least 5 minutes,
as a hot engine can be a fire hazard. Place in a secure
location where it will not be started by untrained
persons.
An appropriate storage location is:
Clean and dry.
•
Away from sources of heat, open flames, sparks
•
or pilot lights, even if the and burner fuel tank is
empty. (Residual fuel vapors from tank can
ignite.)
Away from extreme high or low temperatures.
•
(Do not store the unit in freezing conditions
unless it is prepared as directed in "Winter
Storage Preparation.")
Long-Term Storage Preparation (between
infrequent uses and at end of season)
Prepare for long-term storage if you will not be using
machine again for more than 30 days. Fuel can become
stale when stored over 30 days. Stale fuel causes acid
and gum deposits to form in the fuel system which can
cause the machine to malfunction. To avoid problems,
the fuel system should be emptied or treated with a fuel
preserver before storing the machine longer than 30
days.

Winter Storage Preparation

Machines containing water for cooling or those that use
water during operation need special preparation for
storage during the winter (or freezing) months to prevent
water from freezing in the system.
Note: Long-term storage is treated differently than
between-use storage.
Do not allow water to freeze in the pressure washer,
high-pressure hose, or spray gun. Freezing water will
cause damage to the equipment and can cause the
spray gun to fail in the open position. A spray gun that
has failed in the open position can whip around and
cause personal injury when the pressure washer is
started. Winterize as follows:
Material List:
1. Two 5-gallon buckets
2. 4-5 foot long garden hose or equivalent
(recommend 5/8" to ¾" diameter with male ¾"
Garden hose threads on one end)

Storage

Fig.1574210_10
Procedure:
1. In a 5 gallon pour at least 2 gallons of
environmentally safe antifreeze. Note: whether
using undiluted or pre-diluted antifreeze, follow
manufactures mixing guidelines to ensure
proper freeze protection.
2. Elevate bucket so it is higher than the unloader.
3. Connect a 4-5-foot-long garden hose or
equivalent to inlet connection.
4. To ensure good priming fill hose with water or
antifreeze mix before placing end into 5-gallon
bucket of antifreeze.
5. With the nozzle removed, trigger gun off, and
with burner off point trigger gun into a second
empty 5-gallon bucket and start the unit.
6. With unit running, spray into the empty bucket
for several seconds then release trigger for 2
seconds. Continue cycling the trigger gun
multiple times until all the antifreeze has be
drawn from the supply bucket. Note: if system
was completely flushed you should see
antifreeze in the spray bucket.
7. With unit shut off, remove hoses and drain
excess antifreeze into spray bucket.
8. Properly dispose of antifreeze according state
EPA laws.
