WARNING

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.
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% 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'' 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' area. Failure to comply with this warning
will result in damage to the scale and void the warranty.

1.3 Overview
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 Weigh Center houses the 920i indicator and ticket printer. Figure 1-5 shows the
layout of the control box. Figure 1-6 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 1-5. Weigh Center
The Weigh Center should be given at least 15 minutes to warm up in cold weather
prior to use.
