The following sections describe basic service and maintenance procedures.
4.1 Troubleshooting Guide
The following table lists some of the common problems and their suggested solutions.
4.2 Periodic Maintenance
The space between the platform side and pit frame, and the surface beneath the platform must be periodically
cleaned to prevent debris build up. More frequent cleaning of these areas is necessary with scales mounted in
pits.
Do not attempt to use scales with load cells that are not hermetically sealed in washdown applications. Water
damage is a common cause of failure in non-hermetically-sealed load cells. Use care with high pressure steam
washdowns for hermetically-sealed load cells. The steam may not damage the load cells, but the elevated
temperatures may cause incorrect readings until the unit cools to room temperature.
4.3 Load Cell Replacement
Replacement load cells can be ordered from Rice Lake Weighing Systems according to the part numbers listed
below.
