1.0 Introduction
The Rice Lake Mechanical Chair Scale is designed for the mobile challenged who have a difficult time standing
on a conventional scale. It is ideal for use in clinics and nursing facilities. The scale is durable, having a sturdy
enameled steel body, a durable molded plastic seat, heavy-duty footrest, and heavy-duty caster wheels for easy
portability.
The Rice Lake Mechanical Chair Scale comes in two models:
• RL-MCS: lb/kg (440 lb (200 kg) capacity)
• RL-MCS-10: lb only (450 lb capacity)

2.0 Installation Instructions
You will receive your Mechanical Chair Scale partially assembled. Those items that need additional assembly
are:
• Pillar and beam assembly to scale base
• Steelyard rod connection
• Transport handle onto scale base
• Seat and footrest installation
• Arm rest installation
Remove all components from the shipping crate and lay out in a convenient place.
2.1 Pillar and Beam Installation
The pillar and beam comes separate from the scale base and must be attached prior to use.

Figure 2-1. Pillar and Beam Components
Use the following steps to attach the pillar and beam to the scale base.
1. Have the scale sitting on the floor in an area that allows you to work freely.
2. Lock casters on the frame to eliminate the unit from rolling while assembling the scale.
Push down on latching
assembly to lock
wheels and prevent
scale from rolling.
Figure 2-2. Lock Casters to Keep From Rolling

3. Remove the eight screws from the scale base using a Phillips head screwdriver (as shown in the left hand
photo) and set screws aside in a safe place.
Figure 2-3. Remove Screws From Scale Base and Insert Pillar and Beam into Scale Base Assembly
Insert, but don’t fasten the pillar and beam into the scale base assembly as shown in Figure 2-3 (right hand
side photo).
2.2 Steelyard Rod Connection
The steelyard rod is located inside the pillar. Remove the wire tie(s) holding the steelyard rod during
shipment. Insert the pillar into the base. Once the pillar is inserted to the scale base, the steelyard rod must be
attached to the bottom of the scale. The two photos in Figure 2-4 show the hook of the steelyard rod and an inside
photo of the ring in the scale bottom. Latch the hook onto the D-shaped ring shown in the right hand side picture.

2.3 Installing Transport Handle
Once the pillar and beam are attached to the scale support frame and secured, it’s time to attach the transport
handle to the scale support frame (transport handle is illustrated in Figure 2-6).
1. Remove the four side screws (two on each side as shown in left hand side of Figure 2-6) from the scale
support frame and set aside. The transport handle will attach to the scale support frame using those
screws.

2. Insert the transport handle into the two sides of the scale support frame (shown in right side of
Figure 2-6).
3. Insert and tighten the four screws using a Phillips screwdriver as shown in Figure 2-7.
Figure 2-7. Insert and Tighten Four Screws for Securing the Transport Handle to the Scale Support Frame
The transport handle should fit snuggly against the scale support frame.

2. Set the chair onto the scale support frame platform but do not fasten the screws as the footrest assembly
will also have to be put into place prior to tightening all screws.
3. Remove screws from the chair frame (shown in Figure 2-9) and set aside.
4. Tilt the chair upwards as shown in Figure 2-9. This will allow the installer to get the footrest assembly in
place prior to securing the chair to the platform
Remove four screws from chair
frame (two on each side) and tilt the
chair upwards before installing
footrest assembly.
