1.1 Safety
Safety Symbol Definitions:
Indicates an imminently hazardous situation that, if not avoided,
will result in injury or death.
Indicates a potentially hazardous situation that, if not avoided,
could result in death or serious injury, and includes hazards that
are exposed when guards are removed.
Indicates a potentially hazardous situation that, if not avoided,
could result in minor or moderate injury.
Indicates information about procedures that, if not observed,
could result in damage to equipment or corruption to and loss of
data.
General Safety
Do not operate or work on this equipment unless you have read
and understood the instructions and warnings in this manual.
Contact any Rice Lake Weighing System dealer for replacement
manuals. Proper care is your responsibility.
Failure to heed may result in serious injury or death.
Do not allow minors (children) or inexperienced persons to operate this unit.
Do not operate without all shields and guards in place.
Do not use for purposes other than weighing.
Do not place fingers into slots or possible pinch points.
Do not use any load bearing component that is worn beyond five percent of the
original dimension.
Do not use this product if any of the components are cracked.
Do not exceed the rated load limit of the unit.
Do not make alterations or modifications to the unit.
Do not remove or obscure warning labels.
Keep hands, feet and loose clothing away from moving parts.
Some procedures described in this manual require work inside the indicator
enclosure. These procedures are to be performed by qualified service personnel only.
Always be certain when lowering the scale that everyone is clear of the scale and
any moving parts.
Use two hands when gripping the lift handle to raise or lower the scale.
Be sure the gates are latched or tied inward before transporting the scale.
Ensure all three hitch lock pins are installed and the suspension stops are in the
transport position before moving the scale.
DANGER
WARNING
CAUTION
Important
WARNING

Introduction 3
Livestock scales are not intended for the transportation of livestock or any other
goods. Any addition of weight to the scale while in transport mode can cause
premature component failure and voids the Rice Lake Weighing Systems warranty.
Animal Safety
Animal safety is a very serious issue and must be observed when handling any type
of animal.
The scale surface may become slippery during use; a build-up of manure on the
scale may reduce traction. It is recommended to take any necessary precautions
to maintain an acceptable level of animal footing.
Calibration
Do not calibrate this scale with a weight cart having a gross weight in excess of 25
percent of the total capacity of the scale. See the scale installation manual for
specific calibration instructions. This device is designed to be calibrated with
single block weights spread evenly throughout the floor of the scale. If using a test
cart, use 3/4 inch plywood for testing and calibration. This will minimize the
damage to the x-lug flooring. Shift tests should not be done with more than 4,000
lb or 1,815 kg in a 4 x 4 foot area. Failure to comply with this warning will result in
damage to the scale and void the warranty.

Animal safety is a very serious issue and must be observed when
handling any type of animal. The scale surface may become
slippery during use; a build-up of manure on the scale may reduce
traction. It is recommended to take any necessary precautions to
maintain an acceptable level of animal footing.
The weighcenter houses the 920i indicator and ticket printer. Figure 1-4 shows the
layout of the control box. Figure 1-5 on page 7 shows a close-up of the 920i indicator.
The control box is powered by a deep cycle battery located in the battery box
mounted to the scale frame. This battery is normally charged during towing; however,
if the battery is low, charge it using a trickle charger.
Figure 1-4. Weighcenter
The weighcenter should be given at least 15 minutes to warm up in cold
weather prior to use.

second time.
•Last Weighment — this provides information on the previous group of
animals that were on the scale.
•Current Weighment — this provides information on the number of animals
currently on scale, their total weight and the average weight per animal.
•Totals — this provides information on the total of all animals weighed in the
current weigh batch and their average weight.
10.Unload the scale.
11.Repeat steps 4-10 until all animals from the current batch have been weighed.
