1.1.4 RL101 Scale Warnings
Warning Description
The RL101 scale is considered a lift and weigh device, therefore, use must be limited only to weighing
needs. The RL101 scale is not designed for cargo handling and transportation.
Once load handling is done, move away, and ensure that the load is well balanced by lifting it up only a
few inches from the ground and then lower the load down to the ground. Remove the RL101 scale at the
end of the weighing operations.
Use the scale exclusively for the lifting and the weighing of suspended loads and for tension
measurements. Suspended loads may cause applied torsion stresses and should be hung with flexible
or swiveling bindings.
