1.0 Introduction
The Rice Lake Mechanical Chair Scale is designed for those who have a difficult time standing on a scale. It is
ideal for use in clinics and nursing facilities. The scale is durable, having a sturdy enameled steel body, a molded
polypropylene chair, heavy-duty footrest and heavy-duty caster wheels for easy portability.
The Rice Lake Mechanical Chair Scale comes in two models:
• RL-MCS-LB (450 x 4 oz capacity)
• RL-MCS-KG (200 x 100 g capacity)
Manuals can be viewed and downloaded from the Rice Lake Weighing Systems website at

Do not operate or work on this equipment unless you have read and understand the instructions and
warnings in this Manual. Contact any Rice Lake Weighing Systems dealer for replacement manuals.
Proper care is your responsibility.
General Safety
Failure to heed may result in serious injury or death.
Ensure sure every individual who operates or works with this unit has read and understands the following safety
information.
Do not transport the scale while someone is on it — the scale is not designed for transporting patients.
To avoid cross contamination, the scale should be cleaned regularly.
Do not allow minors (children) or inexperienced persons to operate this scale.
Do not jump on the scale.
Do not use in the presence of flammable materials.
People who are physically frail should always be assisted by another person when getting on and off the scale.
Do not use the scale on slippery surfaces, such as a wet floor.
Do not weigh someone with this scale whose body or feet are wet, such as after they have taken a bath.
Do not use this product if any of the components are loose or cracked.
Do not drop the scale or subject it to violent shocks.
Ensure casters are in a locked position prior to the patient getting on and off the scale.
For accurate weighing, the scale must be placed on a flat, stable surface.
Weight exceeding the maximum rated scale capacity may damage the scale.
Avoid contact with excessive moisture.
The patient should be completely seated in the chair, not leaning forward, and having feet firmly positioned on the footrest
assembly while being weighed.
Do not make alterations or modifications to the scale.
Any alterations voids the warranty.

Pillar
Push down on latching assembly
to lock wheels and prevent scale
from rolling.
The Rice Lake Mechanical Chair Scale will arrive partially assembled. Additional assembly is required for the
following:
• Pillar/beam assembly to scale base
• Steelyard rod connection
• Transport handle onto scale base
• Chair and footrest installation
• Arm rest installation
2.1 Pillar/Beam Installation
The pillar/beam comes detached from the scale base and must be attached prior to use. The following tools will be
needed to assemble the pillar and beam to the scale base.
• Phillips head screwdriver
• Multi-purpose tool (included)
Figure 2-1. Pillar and Beam Components
Use the following steps to attach the pillar and beam to the scale base.
1. Lock the casters on the frame to keep the unit from rolling during assembly.
Figure 2-2. Lock Casters

2. Remove the twist ties from the underside of the platform base. Ties are used to prevent the scale base from
movement during shipping.
Figure 2-3. Remove Twist Ties from Platform Base (Underside of Platform Shown)
3. Remove the eight screws from the scale base and retain for installation. See Figure 2-4.
Figure 2-4. Remove Screws from Scale Base
There is a steelyard rod located inside the pillar.
4. Remove the twist ties used to secure the steelyard rod during shipment.
Figure 2-5. Remove Twist Tie from Steelyard Rod
5. Move the pillar onto the base ensuring that the Rice Lake label on the pillar should be facing the patient/chair.

CAUTION
Important
Use the following steps to attach the transport handle to the scale.
1. Remove the four side screws (two on each side). See Figure 2-8. Retain screws for reassembly.
Figure 2-8. Transport Handle Installation
2. Align the transport handle to both sides of the scale support frame (see Figure 2-9).
3. Insert and tighten the four screws using a Phillips screwdriver (see Figure 2-9).
Figure 2-9. Secure the Transport Handle to the Scale Support Frame
The transport handle should fit snuggly against the scale support frame.
Do not transport the scale while someone is on it — the scale is not designed for transporting patients.

WARNING
To ensure accurate weighments, a zero adjustment must be done prior to first use. To perform a zero adjustment,
1. Ensure the scale is sitting on a level surface.
2. Check the eye loop area on the scale to ensure that the scale pointer is equally balanced in the eye loop.
Figure 3-1. Zero Adjusting Screw Location (pound model shown)
3. Turn the zero adjusting screw until the scale pointer is in the center of the eye loop when set to zero.
4. The scale is now ready to weigh patients.
The patient should be completely seated in the chair, not leaning forward, and having feet firmly
positioned on the footrest assembly while being weighed.
