SAFETY PRECAUTIONS
Pesticides can cause personal injury and harm the environment when used improperly. Be
sure to follow label recommendations concerning safety and disposal. Observe all safety
precautions including wearing of protective clothing and equipment.
The Spreader-Mate is designed to fit into many, but not all, commercial broadcast spreaders.
Be sure that the overall weight does not exceed the spreader manufacturer’s
recommendations. A full tank and all hardware will add 102 lbs. to the spreader.
Use extreme caution to avoid tipping of the spreader.
Calibrate and test using clean water.
Check with each use for leaks or damage.
SET-UP PROCEDURE
Your Spreader-Mate was pressure tested prior to shipment. Some components were
disassembled for packaging and shipment. The basic set-up procedure is as follows:
Remove the spray wand from inside the tank.
Remove all contents from the box.
Cut the plastic ties holding the boom sections together.
Report any missing or damaged items to your dealer immediately.
NOTE: The pink liquid residue in the tank is RV antifreeze. Flush out the tank before
use. (See page 6)

Install the boom on the front of the

on the tubular hopper support of the
spreader. Center the vertical mounting
brackets horizontally and mark the two hole
locations. Set the boom assembly aside
and drill two 1/4-inch diameter holes for the
mounting hardware.
Mounting Holes
Place the 1-1/2 inch diameter washers on the inside of the hopper wall and insert the 1/4-20 hex
head bolts in the holes. The bolt heads should be inside the hopper. They should be snug and
will need to be screwed into the holes. Replace the boom assembly and align the bolts with the
mounting holes. The small lockwashers and wingnuts are used to secure the boom while in use.

GENERAL OPERATION AND MAINTENANCE
The sprayer pump is turned on and off by the thumb switch mounted on the handlebar of the
spreader. Each dripless nozzle body has a special shut-off cap. The nozzle body requires 5
psi of system pressure to open, thus keeping the nozzles from dripping when the pump is
off. The nozzles can be completely shut off by turning the cap clockwise. The operator can
turn off individual nozzles as needed. The hand spray wand is activated by closing the boom
line valve (ball valve on top of the tank) to turn off flow to the boom. To drain the tank of
unused liquids, remove the spray tip from the wand and pump the remaining liquid into the
proper receptacle.
• Clean pump filter daily. • Adjust hinge lock nut tension as necessary.
• Clean tip screens regularly. • Flush with water after each use.
• Prevent from freezing. • Lubricate hinges with grease.
INITIAL START UP AND PRESSURE TESTING
1. Turn the pressure regulator knob counter-clockwise all the way.
2. Put about one gallon of water in the tank for testing.
3. Be sure that the boom line valve is turned off.
4. Turn on the handlebar thumb switch. You should hear the pump running and see
water moving through the hoses.
5. Slowly turn the pressure regulator knob clockwise to increase the pressure. You
should notice movement of the needle on the pressure gauge. Adjust the pressure
to 30 psi for testing.
6. With the spray wand assembled, operate the trigger valve and check it for leaks.
Note the trigger lock. Also adjust the nozzle and angle adapter orientation to the
desired position.
7. Turn off the switch. Turn on the boom line valve and all four caps on the top of
each boom nozzle body.
8. Turn on the switch and observe the spray pattern from each boom nozzle. Check
the entire boom assembly for leaks.
9. Flush out the water and antifreeze. Once the unit has been pressure tested and
you are familiar with its operation, you can begin the calibration procedure.
BATTERY RECHARGING
The Spreader-Mate battery is a sealed, maintenance-free 12-volt battery. Charging at a low
rate (3 amp max.) with an automotive-quality battery charger will extend battery life.
A 110-volt powered plug-in battery charger is available as an optional accessory to recharge
the battery when not in use. The battery can also be recharged by the service truck’s
charging system by using the optional vehicle charging kit.

CALIBRATION
The Spreader-Mate is equipped with Turbo TeeJet Air Induction nozzles. The nozzle table
below will serve as a reference for application rates. The nozzle spacing is 20 inches. The
pressure is adjustable. A working pressure of 20 psi will provide adequate coverage. A four-
inch overlap of the previous spray pass is recommended.

Table 1
Because walking speeds vary, it is always best to perform a field test to confirm the
application rate. The procedure is simple:
1. Measure an area at least 10,000 square feet.
2. Fill the tank with water.
3. Spray the measured area at 20 psi and at a comfortable sustainable walking speed.
4. Refill the tank from a calibrated container keeping track of the amount needed to refill
the tank.
5. Divide the number of gallons used by the square footage of the area sprayed
(Expressed in 1000 square foot increments)
6. Since the tank holds 9 gallons, divide 9 by the result to obtain the expected coverage
per tank full.
Example: 4.5 gallons used
10,000 square feet sprayed
4.5 divided by 10 = .45 gallons per 1000 square feet
9 divided by .45 = 20
The capacity is 9 gallons, so in this example a full tank should cover 20,000 square feet.
