STORAGE & MAINTENANCE

SPECIFIC MAINTENANCE:

PUMP: The pump oil must be changed after the first 25 hours of operation.
Once the initial oil change has been completed, it is recommended the
oil be changed every 3 months or 250 hour intervals. If oil appears
dirty or milky, changes may be required at a greater frequency. Use
SAE20 or 30 non-detergent pump oil and fill only to the center of
the oil sight glass. DO NOT OVERFILL!
NOZZLES: Nozzle orifices should be kept clean and free from obstructions. To
clean nozzle orifice:
. Disconnect the wand from the gun.
2. Insert the nozzle cleaner into the nozzle and rotate. (See draw-
ing, left.)
3. Flush the nozzle with water.
4. Reconnect the wand to the gun assembly.
5. Turn the unit "ON". Point the gun in a safe direction and trigger
the gun to begin spraying. Adjust spray pattern to 0°. If spray
pattern is still distorted, repeat steps -4. If you are unable
to thoroughly clean the nozzle using this procedure, then the
nozzle must be replaced. Water flow through the spray nozzle
will erode the orifice, making it larger, resulting in a pressure
loss. Nozzles should be replaced whenever pressure is less
than 85% of the maximum. The frequency of replacement will
depend upon such variables as mineral content in the water
and number of hours the nozzle is used.
To remove or replace adjustable nozzle:
. Insert a 2.0 mm allen wrench into the nozzle.
2. Rotate the wrench counterclockwise to remove the nozzle.
3. Inspect the nozzle and clean or replace before reinserting.

WINTERIzING:

For storage and transportation purposes in subfreezing ambient temperatures,
it will be necessary to winterize this unit. This unit must be protected to the
lowest incurred temperature for the following reasons:
. If any part of the pumping system becomes frozen; excessive pressure may
build up in the unit which could cause the unit to burst resulting in possible
serious injury to the operator or bystanders.
2. The pumping system in this unit may be permanently damaged if frozen.
FREEZE DAMAGE IS NOT COVERED BY WARRANTY.
If you must store your unit in an area where the temperature may fall below 32°F,
you can protect your unit by following the procedure outlined below.
. Gather the following items:
a. Two 5 gallon containers.
b. One gallon of antifreeze. (The manufacturer recommends an
environmentally safe antifreeze.)
c. Water supply.
d. Three foot hose, 1/2-3/4 I.D. with a 3/4 inch male garden hose fitting.
