ii Mechanical Chair Scale Installation and Operation Instructions

1.0 Introduction

Internet

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) This manual can be viewed and downloaded from the Rice Lake Weighing Systems web site

2.0 Installation Instructions

Beam

Pillar

Push down on latching assembly to lock wheels and prevent scale from rolling.

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.

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.

Figure 2-1. Pillar and Beam Components

Figure 2-2. Lock Casters to Keep From Rolling

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 photo of the ring in the scale bottom. Latch the hook onto the D-shaped ring shown in the right hand side picture.

Figure 2-4 show the hook of the steelyard rod and an inside

2.3 Installing Transport Handle

Transport handle

Side screws x 4

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

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.

Figure 2-6. Transport Handle Installation

Figure 2-6).

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.

2.4 Seat and Footrest Installation

Four screws on scale support frame - only one screw shown

Remove four screws from chair frame (two on each side) and tilt the chair upwards before installing footrest assembly.

Once the transport handle is attached the next step is to install the molded seat to the scale support frame.

1. Remove the four screws from the movable scale support frame platform and set aside.

Figure 2-8. Removable Screws on The Movable 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.

5. Slide the footrest assembly onto the chair scale base as shown in Figure 2-9. Note that the footrest assembly for the footrest is hanging on the metal chair channel and lined up with

the screw holes on the channel of the chair scale frame as shown in

Figure 2-9. Tilt the Chair Upward Before Installing the Footrest Assembly

Figure 2-10.

Mechanical Chair Scale Installation and Operation Instructions - Installation Instructions 5

Push footrest assembly back so that the holes line up.

Secure screws (only one shown)

Figure 2-10. Slide the Footrest Assembly So That Holes Line Up

Once the footrest is secured and the screws tightened for it, secure the molded seat onto the chair scale frame.

6. Secure the four screws (shown below).

2.5 Arm Rest Installation

The last item to be installed on the mechanical chair scale are the two arm rests.

Use the following steps to attach the two arm rests to the mechanical chair scale molded seat.

1. Locate the bolt hole (x 4) location on the back of the molded chair.

two bolts for each arm rest

3.0 Zero Adjustment

Eye Loop Area

Zero Adjusting Screw

Scale pointer

T o ensure accurate weighments, a zero adjustment should be done to the scale upon arrival and setup. To perform a zero adjustment, perform the following steps.

1. Ensure the scale is sitting on a level surface.

2. Check the eye loop area of the scale to ensure that the scale pointer is equally balanced between the eye loop area.

Figure 3-1. Eye Loop Area and Zero Adjusting Screw Location (Lb/Kg model shown)

3. If the scale is not balancing properly, then the small zero balance weight must be adjusted. Turn the zero adjusting screw (shown in Figure 3-1) using a flat head screwdriver. By adjusting the screw, the zero balance weight will move accordingly.

4. The scale is now ready to weigh patients.

5. Have the patient sit down on the molded seat. The patient should be completely seated in the chair, not leaning forward, and having feet firmly positioned on the footrest assembly.
