3.0 Scale Assembly

Important
Note

3.1 Unpacking Your Scale

Place the unopened box in an open area that has ample room for unpacking the scale.
Parts contained in the shipping box include:
• The scale
• This manual
• Small box containing AA batteries (6) and scale feet.

3.2 Repacking

If the Digital Wheelchair Scale with seat must be returned for modification, calibration or repair, it must be properly packed with sufficient packing materials. Whenever possible, use the original carton when shipping the scale back.
Damage caused by improper packaging is not covered by the warranty.

3.3 Setting Up Your Scale

Use the following steps to set up the Digital Wheelchair Scale with seat.
1. Locate the manual from inside the box removal and set up.
2. Move the scale into the area where the weighing process will occur on a hard, level surface for the most accurate weighments. Thin carpeting is fine but not recommended.
3. Using two people, remove the scale out of the packaging material of the box by the scale base.
and set aside as it will provide instructions on the proper scale
. It’s recommended to place the scale

DO NOT lift the scale out of the box by its handle as this can cause the hinges to break.

3.4 Attaching the Feet to the Scale

Note
Note
The Rice Lake Digital Wheelchair Scale comes with four feet that must be attached to the scale base for proper operation. The four feet are located in the parts box in the original shipping box. Prior to laying the scale base on the floor, use the following steps to attach the feet to the scale.
1. Screw the four round feet clockwise into the scale base as shown in Figure 3-1.
Figure 3-1. Screw Feet Into the Scale Platform
2. There must be adequate clearance between the scale base and the floor to screw each foot out counterclockwise two full turns. This will ensure that there is enough clearance between the scale base and the floor.
3. Gently set the scale base down to the floor. There s
hould be minimal clearance between the scale base and the floor without having the scale base actually touching the floor. Figure 3-2 shows the width of a finger being slid between the scale base and the floor.
By not having clearance around the scale base will create inaccurate weighments.
Figure 3-2. Have a Minimal Amount of Clearance Between the Scale Base and the Floor
4. It is also important to make sure that the scale is completely level. Gently press down on all corners of the scale base to ensure that there are no high spots or rocking of the scale base.
An un-level base will produce inaccurate weight readings.
