  • Page 6: Introduction

    The CLS-420 Cargo Lift Scale is a rugged, dependable cargo lift scale that can withstand many years of repeated use. When mounted on a forklift, the CLS-420 saves time and money by allowing you to weigh loads immediatel y instead of carrying the load to a floor scale.
  • Page 7 Do not operate or work on this equipment unless you have read and understand the instructions and warnings in this manual. Failure to follow the instructions or heed the warnings could result in injury or death. Contact any Rice Lake Weighing Systems dealer for replacement manuals. Proper care is your responsibility.

  • Page 8: Considerations Before Installation

    While the CLS-420 Cargo Lift Scale will fit most typical forklifts, there are certain considerations that must be taken into account prior to installing the scale. Due to the extra weight of the CLS-420, the net lifting capacity of the forklift scale is decreased by approximately 10%. Use the formula below to calculate the net capacity of the unit.
