MAINTENANCE
Cleaning
The base components should be kept clean and free of excessive material build up.
• Damp cloth with water and a mild detergent may be used to wipe clean the external surfaces—do not use acids,
alkalis, strong solvents or abrasive materials and chemicals
Troubleshooting
Aside from installing components and leveling adjustments, the Defender Series Base does not require any other adjustments as
shipped from the factory.
Operational difficulties that may be encountered can often be traced to simple causes such as:
• Loose or incorrect wiring connections
• Obstructions to the base frame
• Unstable environments
• Incorrect calibration or setup of the indicator
