ASSEMBLY INSTRUCTIONS
35’ SEED HOSE ASSEMBLY
STEP 1. Attach the 1300-124 seed hose assembly to the 2 1/4” airlock fitting and secure with the 2570-
716 muffler style clamp. DO NOT OVER TIGHTEN THE CLAMP.
STEP 2. Attach the 1300-166 cyclone exhaust kit to the seed cyclone. Left hand thread the 2515-712 hose
cuff onto the 1300-553 3 1/8” OD vinyl hose. Then insert the hose and cuff assembly into the top of the
cyclone. Using plastic tie straps, tie the vinyl hose to the stainless steel seed hose using the (3) 2515-405
black cable ties.

ASSEMBLY INSTRUCTIONS
STEP 3. Attach the 1300-163 cable assembly to the 1300-124 seed hose assembly. Connect the 1300-
163 cable to the power unit’s module at the plug connector labeled “switch input”. Inspect the plug
connector for dirt, debris or bent pins; clean and repair the connectors if necessary.
STEP 3. CONTINUED….Coil the cable assembly around the seed hose. Install the toggle switch to the
cyclone handle and secure with the jam nut.
STEP 4. Tape the seed hose assembly and the cable assembly together at regular intervals to prevent
snagging and damaging of the cable assembly.

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!
10
MAINTENANCE
WARNING: Never clean, lubricate or adjust a machine that is in motion. Failure to heed may result in serious personal
injury or death.
1. Inspect daily and clean safety decals. Replace if torn or no longer functional.
2. Inspect daily the air cleaner element and clean or replace as required.
3. Inspect daily and retighten, as required, all bolts on the power unit and assemblies.
4. Inspect daily and repair, as required, all air hoses and fittings.
5. See blower manual for proper lubrication.
6. Inspect, refill and replace the blower oil per the instructions in the blower manual.
7. Inspect the airlock assembly, it must turn freely.
8. Do not allow the airlock assembly and the blower to be exposed to water.
9. Lubricate the airlock with “fogging oil” before and after the in-use season.
10. Clean and lubricate the machine before putting into storage. Do not leave seed or seed treatments/inoculants in or near the airlock.
STORAGE
1. Inspect, refill and replace the blower oil per the instructions in the blower manual. Use a high quality hydraulic oil.
2. Inspect the airlock assembly, it must turn freely.
3. Do not allow the airlock assembly and blower to be exposed to water, moisture or condensation. Store in a clean dry area.
NOTE: If airlock and/or blower are exposed to water they will rust and may cause NON-REPAIRABLE internal damage.
4. Lubricate the airlock and blower with “fogging oil” before and after the in-use season.
5. Clean and lubricate the machine before putting into storage. Do not leave seed or seed treatments/inoculants in or near the
airlock.
IMPORTANT: Do Not Use a pipe wrench to free a stuck airlock.
6. Remove hoses from all fittings, cap or cover the hoses, airlock and blower fittings to repel rodents and moisture and to seal in
lubricants.
7. Gasoline engines stored over 30 days need to be protected or drained of fuel to prevent gum from forming in fuel system or
essential carburetor parts. For gasoline engine protection, we recommend use of Briggs & Stratton fuel stabilizer available
from an authorized Briggs & Stratton service dealer. Mix stabilizer with fuel tank or storage container. Run engine for a short
time to circulate stabilizer through carburetor. Engine and fuel can be stored up to 24 months.
NOTE: If stabilizer is not used or if engine is operating on gasoline containing alcohol, e.g. gasohol, remove all fuel from tank and run engine until it
stops from lack of fuel.
STORAGE PROCEEDURES FOR GAS/LPG/NG ENGINES
1. Change oil.
2. Remove spark plug and pour about 15 ml (1/2oz.) of engine oil into cylinder. Replace spark plug and crank slowly to distribute oil.
3. Clean chaff and debris from cylinder and cylinder head fins, under finger guard and behind muffler.
4. Store in a clean and dry area, but NOT near a stove, furnace or water heater which uses a pilot light or any device that create a spark.

Our name
Is getting known
Just a few years ago, Yetter products were sold primarily to the
Midwest only. Then we embarked on a program of expansion and
moved into the East, the South, the West and now north into Canada.
We’re even getting orders from as far away as Australia and Africa.
So, when you buy Yetter products . . .you’re buying a name that’s
recognized. A name that’s known and respected. A name that’s
become a part of American agriculture and has become synonymous
with quality and satisfaction in the field of conservation tillage.
Thank you.
