Safety Instructions
Section
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 OSHA Standard 1910.147. This standard “requires employers to establish
a program and utilize procedures for affixing appropriate lockout devices or tagout de-
vices 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 pre-
vent injury to employees.”
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 equipment may be 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.

LOSS IN WEIGHT SLIDE GATE AND ATOMIZER CHAMBER
The atomizer chamber consists of a patented design which disperses treatment evenly
to each seed. A motor drives the atomizer head at approximately 1725 RPM’s.
As treatment is being pumped into the atomizer chamber, it drops into the atomizer
head. The centrifugal force of the spinning head forces the treatment to be sprayed
out through a screen covering in all 360 degrees. Meanwhile, seed flows down out of
the box, through the seed gate and down on top of the distribution cone which dispers-
es the seed down around the atomizer head. The atomizer can be easily accessed for
cleaning and maintenance by pulling down on the quick release handle and sliding the
atomizer away from the treater body (see page 53).

The pump stand utilizes a variable speed pump motor and special norprene pump
tubing for liquid metering. Each pump comes equipped with 1 peristaltic pump head.
Liquid will only come into contact with the inside diameter of the pump tubing and not
the pump. This allows for easy cleanup and less maintenance of the pump.
To open the pump head, rotate the lever to the left. Place the pump tubing inside the
pump head so it fits inside the notches and above the rollers (bottom, left). Rotate the
lever back to the right and close the pump head, clamping the hose inside the head
(bottom, right). Wear or fatiguing of the tubing within the pump head due to compres-
sion 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 pump
stand for several days or when storing, open the pump head and remove the tubing to
prevent any extra compression.
