3.2Repacking
If the Rice Lake Digital Wheelchair Scale 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.
Move the scale into the area where the weighing process will occur. It’s recommended to place the scale on a
hard, level surface for the most accurate weighments. Thin carpeting is fine but not recommended.

proper scale removal and set up.
2. Using two people, remove the scale out of the packaging material

3.4Attaching 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. 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 3-4.
Figure 3-4. Screw Feet Into the Scale Platform
2. There must be adequate clearance between the scale base and the floor so 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 3-5 shows the width of a
finger being slid under the scale base and the floor.
By not having clearance around the scale base will create inaccurate weighments.
Figure 3-5. 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 unlevel base will produce inaccurate weight readings.
5. Loosen the handles (shown in Figure 3-6) and set upright.
Figure 3-6. Loosen the Durable Hinges to Set Handles Upright
6. Tighten the two hinges on the Rice Lake Digital Wheelchair Scale by rotating the two handles. This will
secure the handrail mounted indicator.
3.5Inserting Batteries
The six AA batteries that come with the scale offer an average of 25 hours of continuous use.
To install the batteries,
1. Open the battery chamber cover by loosening the thumbsc
