A
Every year accidents in the work place maim, kill, and injure people. Although it
may be impossible to prevent all accidents, with the right combination of training,
operating practices, safety devices, and operator vigilance, the number of accidents
can be significantly reduced. The purpose of this section is to educate equipment
users about hazards, unsafe practices, and recommended hazard avoidance
techniques. SAFETY WORDS AND SYMBOLS
It is very important that operators and maintenance personnel understand the words
and symbols that are used to communicate safety information. Safety words, their
meaning and format, have been standardized for U.S. manufacturers and published
by the American National Standards Institute (ANSI). The European Community
(E.C.) has adopted a different format based on the International Standards
Organization (I.S.O.) and applicable machinery directives. Both formats are
presented below. Graphic symbols are not standardized, but most manufacturers
will use some variation of the ones seen in this manual.
Indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.
Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury and/or
property damage.
Provides additional information that the operator needs to be
aware of to avoid a potentially hazardous situation.

LOCKOUT / TAGOUT PROCEDURES
Lockout/Tagout is the placement of a lock/tag on an energy isolating device in
accordance with an established procedure. When taking equipment out of service
to perform maintenance or repair work, always follow the lockout/tagout procedures
as outlined in ANSI Z344.1 and/or OSHA Standard 1910.147. This standard
“requires employers to establish a program and utilize procedures for affixing
appropriate lockout devices or tagout devices to energy isolating devices and to
otherwise disable machines or equipment to prevent unexpected energizing,
start-up, or release of stored energy in order to prevent injury to employees.”
EMERGENCY STOP
There are two Emergency Stop push buttons on the MX Series Seed
Treater, which are located on the main control panel and the treater
junction box. Actuators of emergency stop shall be colored RED. The
background immediately around the device actuator shall be colored
YELLOW. The actuator pushbutton-operated device shall be of the palm
or mushroom head type.
CONTROLLED STOP
This is the stopping of machine motion by reducing the electrical command signal to
0 (zero) once the stop signal has been recognized.
HAZARD REVIEW
Electrocution Hazard
Electrocution accidents are most likely to occur during maintenance of
the electrical system or when working on or near exposed high voltage
wiring. This hazard does not exist when the electrical power has been
disconnected, properly locked, and tagged out.
Automatic Start Hazard
This seed treating system is usually controlled by an automated system
and may start without warning. Failure to properly disconnect, lockout,
and tagout all energy sources of remotely controlled equipment creates a
very hazardous situation and could cause injury or even death. PLEASE
STAY CLEAR AND BE ALERT.

4. Remove any boxes from the drum of the treater.
5. Install the four legs provided and set up on a level surface, preferably concrete.
When all four legs are mounted in the same pin hole, the seed treater has a slight
slope to allow seed to travel through the machine. The pin holes are
approximately 2” apart.
If more slope is desired, the rear legs can be dropped an additional pin
hole.
6. Anchor the seed treater in position to prevent the machine from moving during
operation.
7. Inspect machine thoroughly for screws, bolts, fittings, etc. which may have come
loose during shipping.
8. The pump stand should be placed on level ground close to the seed treater.
9. Attach the tubing from the pump skid to the atomizer on the seed treater (below
left). Additional tubing can be added or removed to accommodate your set-up.

SUPPLY HOPPER & SEED WHEEL
The hopper is equipped with three proximity switches. The top switch controls the
inlet conveyor and the lower switches, located in the seed wheel, control the
pump(s). Refer to “H-O-A Screen” in section D and Section F: Troubleshooting;
“Proximity Switch Adjustment Guide” for more in-depth information on these
switches.
The Seed Wheel is designed to simplify and increase seed flow calibration
accuracy. A rotating wheel is driven by a variable speed motor, which is set prior to
treating the seed. This is mounted above the atomizer. The wheel consists of 8
identical pockets approximately 4 inches deep. As it rotates, the wheel captures a
certain amount of seed in each pocket. After the seed is caught, the wheel
continues rotation and dispenses the seed into the atomizer chamber. With the
constant turn of the wheel, there is a consistent amount of seed always sent through
the atomizer.
A cup is used to represent a certain percentage of one of the wheels pockets. To
calibrate the seed flow, take a sample of the seed to be treated using the cup and
weigh it. From the weight of the seed sample and by also knowing the RPM of the
wheel, you can determine how fast that seed type will pass through the seed treater.
The purpose of the seed wheel is to simplify calibration and make seed flow
calibration more accurate. The seed wheel saves time when switching to different
seed sizes and seed types.

ATOMIZER CHAMBER
The atomizer chamber consists of a patented design which disperses treatment
evenly to each seed. A variable speed motor drives the atomizer head. As
treatment is being pumped into the atomizer chamber, it drops into the atomizer
head. The centrifugal force of the spinning head causes the treatment to be
sprayed out through a screen covering all 360 degrees. Meanwhile, seed drops
down out of the seed wheel, down on top of a distribution cone, and down through
the atomizer chamber. The distribution cone creates a curtain of seed which wraps
around the atomizer head, ensuring that every seed is applied with treatment.
ROTATING DRUM
The stainless steel rotating drum accepts treated seed through the opening on the
hopper end. As seed passes through the length of the drum it is tumbled,
producing accurate and uniform seed coating. The seed then exits the seed treater
out the discharge end of the machine.
Never allow exposure of persons or clothing to the drive shaft,
idler wheels, or the drum during operation. Always have the
safety shields in place during operation.
PUMP STAND
The USC MX series seed treater is equipped with a 50-gallon mix tank with an
electric drive liquid agitator to keep chemicals mixed and in suspension. The
agitator should be running at all times when chemical is present. The tank is
equipped with a shut-off and drain valve located on the bottom. The tank sits atop
a scale which is used to measure out product.
The pump stand utilizes a variable speed peristaltic pump with 3 pump heads and
special neoprene pump tubing for chemical metering. The liquid being used only
comes into contact with the inside diameter of the tubing and not the pump. This
allows for easy cleanup and maintenance without disassembling the pump.
To open the pump heads, turn the levers to the left. Place pump tubing inside the
pump heads so it fits inside the notches and above the rollers. Turn lever back to
the right to close the pump head, clamping the hose inside the head. Wear or
fatiguing of the tubing within the pump head due to compression is normal. When
tubing becomes worn or chemical rates begin to slow down, open the pump head
and move the tubing to a different position. If the entire piece of tubing becomes
worn, simply replace with a new section. When not using the seed treater for
several days or when storing, open the pump head and remove the tubing to
prevent any extra compression. Worn tubing should be moved to a different
position every week to prevent additional wear.

USC, LLCPage 20
MX2500
If a very low rate is needed, a section of tubing can be removed to force the pump
motor to run at a higher speed. This allows for a more consistent flow rate. When
removing the tubing, uncouple it from the manifold (below left). If the tubing is
unclamped from the pump head but left coupled in the manifold (below right), the
pump will suck air and cause flow rates to be very inconsistent.
