1.0 Introduction
The Rice Lake Digital Bariatric Handrail Scale with fold down seat is designed for weighing bariatrics and
ensures sound, accurate weighing information. A non-skid platform paired with side rails assists persons who
need extra support and safety. The fold down chair allows patients to sit down while being weighed. The scale is
set up to use motion sensing technology, to determine the actual weight of a moving patient. The weight is
displayed on the indicator and can be displayed in pounds or kilograms and has a 1000 lb capacity.
This manual can be viewed and downloaded from the Rice Lake Weighing Systems
web site at www.ricelake.com/health. Technical information on this product and other
medical products are available on the Rice Lake Weighing Systems web site.

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
• Six AA batteries
• 6 mm Allen Key
3.2 Repacking
If the Digital Bariatric Handrail Scale must be returned for modification, calibration or repair, it must be properly
packed with sufficient packing materials. Whenever possible, use 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 Bariatric Handrail Scale with seat.
1. Locate the manual from inside the box and set aside as it will provide instructions on the proper scale
removal and set up.
2. 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.
3. Using two people, remove the scale out of the packaging material that it came in by lifting the scale out
of the box by the scale base.
DO NOT lift the scale out of the box by its handle as this can cause the hinges to break.
4. Gently set the scale platform down to the floor.
5. Loosen the handles and unfold and set upright (handles shown in Figure 3-1).
6. Tighten the two hinges on the scale by rotating the two handles. This will secure the handrail mounted
indicator.
Figure 3-1. Secure the Handrail by Tightening the Durable Hinges
7. Screw in all four legs.
8. Attach the wrap around rails.
9. Tighten the hex screw head using the enclosed 6 mm Allen key to stabilize the scale.
Important
Note

4Bariatric Handrail Scale Operation Instructions
Adjusting the Scale Feet
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.
Gently set the scale base down to the floor. There should be minimal clearance between the scale base and the
floor without having the scale base actually touching the floor. By not having clearance around the scale base
will cause inaccurate weighments.
It’s 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.
Unfold Platform Seat
The Digital Bariatric Handrail Scale comes with a fold down seat for those patients who need to be weighed
while seated. To unfold the seat, simply pull down on the seat bottom as shown in Figure 3-2.

2. Insert batteries into the battery chamber as shown in Figure 3-3.
Figure 3-3. Battery Chamber
3. Close the battery chamber.

3.5 AC Power Connections
