Selecting the Location

To ensure accuracy, proper performance and safety, locate and operate the base on a stable, level surface. Avoid
locations with rapid temperature changes or excessive dust, air currents, vibrations, electromagnetic fields or heat.
Level the base by adjusting the four leveling feet until the bubble in the level indicator is centered. A wrench may
be needed to loosen the locking nut above each leveling foot. When the base is level, retighten the locking nuts up
against the base to lock each foot into place.
Note: Ensure that the base is level each time its location is changed.

MAINTENANCE

Cleaning
The base components should be kept clean and free of excessive material build up.

A 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.
To maintain surface integrity, do not allow debris to remain on the surface of the painted or stainless steel base
frame.

Remove the pan and use fresh water to clean the base frame surface of any debris. Dry the base with a
clean cloth or allow to air dry before replacing the pan. Repeat daily for best care.

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

Failure to remove the shipping spacers

Obstructions to the base frame

Unstable environments

Incorrect calibration or setup of the indicator
