8-2 Equipment Maintenance
This section describes routine equipment maintenance, in particular cleaning methods, inspection
methods, and handling methods when replacing Slave Units.
Perform the following cleaning regularly to ensure the equipment is kept in the best condition possible.
• Wipe the equipment over with a soft, dry cloth when doing daily cleaning.
• If dirt remains even after wiping with a soft, dry cloth, wipe over with a cloth that has been wet with a
sufficiently diluted detergent (2%) and wrung dry.
• Units will become stained if items such as rubber or vinyl products or adhesive tape are left on the
Unit for a long period. Remove such items during regular cleaning.
Precautions for Correct Use
Never use benzene, thinners, or other volatile solvents, or chemical cloths.
The unit coating may change if these products are used.
Always perform periodic inspections to ensure the equipment is kept in the best possible condition.
Periodic inspections should occur every 6 months to a year.
Periodic inspections should occur more frequently, however, for Units that are used in environments
subject to high temperatures, high humidity, or a lot of dust.
The following materials are required to perform periodic inspections.
Materials used regularly
• Phillips screwdrivers and flat-blade screwdrivers
• Screwdrivers for communications connectors
• Testers (or digital voltmeters)
• Industrial alcohol and pure cotton cloth
Materials sometimes required
• Synchroscope
• Pen oscilloscope
• Thermometer and hygrometer
