SYSTEM HOOK UP AND USE
These instructions are to describe the typical set up of the Seed Jet II on a gravity flow wagon towed
by a pickup truck.
1. Place power unit assembly in pickup bed and hitch truck to gravity wagon.
2. Assemble the rubber flex hose from the blower to inlet side of airlock using the quick coupler
half provided and four hose clamps along with sufficient length of hose. Less hose will be
required if the tailgate is lowered. Attach the hose, where required, to the frame of the wagon
with cable ties (not supplied) to prevent interference with any moving parts of the wagon such as
steering mechanisms or tires.
3. Run the duplex wire along a similar route to the hose and secure where necessary to prevent
interference with any moving parts of the wagon such as steering mechanisms or tires.
4. After uncoupling the quick coupler at the blower and weather pack wire connector, the pickup
truck may be quickly and easily unhitched from wagon for other uses.
5. The roll of stainless steel flex hose is to be connected to the airlock output.
6. To prolong engine and blower life always allow the engine to run at fast idle for at least a minute
before running at full throttle. In operation the engine must run at full throttle for satisfactory
performance of the seed system.
7. The switch mounted on the cyclone controls the rotation of the airlock, powered by the 12v
motor. Correct airlock rotation is clockwise on the end of the shaft opposite the electric motor.
DANGER: BEWARE OF UNEXPECTED START UP BY ANOTHER PERSON.
8. Adjust slide door opening on gravity wagon so as to keep hopper full but not overflowing. It is
advisable to close slide door and empty hopper before transporting the unit. Seed left in the
airlock and exposed to moisture could swell and damage the airlock assembly.
9. Adjust the slide gate in bottom of hopper to maximum opening without overloading the engine
and blower.
10. Always shut off airlock and allow hose to clear of grain before throttling down the engine and
shutting off the whole system.
NOTE: There is a time delay from turning off the switch to when the material quits flowing from
the cyclone, some practice may be necessary for precise filling of seed boxes!
