Operator’s Manual

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:

1. 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.
1.  Gather the following items:

a.  Two 5 gallon containers.

b.  One gallon of antifreeze.  (John Deere 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.

2.  Procedure:

a.  To start winterizing, unit must be run and primed according to the "Start-

up Procedures" listed on page 14.

b.  After running and priming, shut off the unit and water supply.

c.  Relieve system pressure by pointing the trigger gun in a safe direction 

and squeezing the trigger until  water flow ceases to exit the nozzle.

d.  Lock the trigger gun in an OFF position and remove the nozzle.

e.  Remove the water supply hose from the unit and attach the 3 foot hose 

securely to the inlet connection.

f.  Shut off the detergent injector if applicable. 

g.  Fill one 5 gallon bucket with water.

h.  Holding the 3 foot hose in an upright position, completely fill the hose 

with water.  Then plug the hose outlet with  your thumb or finger.  Place 

the plugged end into the 5 gallon bucket of water.

i.  Turn the unit on.  Trigger the gun several times until all the air is worked 

out of the system (unit is primed).

j.  With the trigger gun held open, siphon enough water out of the 5 gallon 

bucket until there is just enough water left to mix with the antifreeze.

k.  Point the wand into the empty container and start the unit.

l.  Trigger the gun until the antifreeze begins to exit the wand.  Release 

the trigger for 3 seconds, then trigger the gun for 3 seconds.  Continue 

cycling the gun several times until all the antifreeze mixture is siphoned 

from the container.

m.  Detach the 3 foot hose from the unit and drain any excess antifreeze 

back into the 5 gallon container.

n.  Disconnect the hose/gun/wand assembly from the unit and drain any 

excess antifreeze back into the 5 gallon container.

o.  Store the hose, gun and wand with the unit in a safe area.

p.  Store antifreeze solution for next use or dispose of according to state 

EPA laws.
