4.0 MAINTENANCE
Regularly scheduled maintenance will prolong the operational life and appearance
of the equipment.
Clean the dome with a nonabrasive cleaning cloth and antistatic cleaner that is safe
for use on acrylic plastic. Do not use kerosene or similar substances that can scratch
the surface.
The dome drive should also be inspected and any dust and debris blown off. Pay
special attention to the spur gear drives. After removing dust and debris a film of
silicone lubricant should be applied to both pan and tilt spur gears for prolonged
gear life. It is recommended that the unit be checked at six-month intervals.
No adjustments are required.
