Maintenance
The following section provides instructions for maintaining and cleaning the Rice Lake line of scales. Maintenance operations
other than those described in this section should be performed by qualified service personnel.

Basic Maintenance
Before the first use of the scale and after periods of non-use, check the scale for proper operation and function. If the scale
does not operate correctly, contact qualified service personnel.
Go through the following steps for basic maintenance.
1. Check the overall appearance of the entire scale for any obvious signs of damage.
2. Inspect the condition of the AC adapter for cord cracking or fraying or for broken or bent prongs.
5.2.2
Cleaning
Proper care and cleaning is essential to ensure a long life of accurate and effective operation. Before beginning the cleaning
process, disconnect the scale from the AC power source.
