14.3 Basic Lubricant Service Interval
Bettis actuators must be serviced 10 years after delivery by Bettis Antriebstechnik GmbH,
A-1230 Vienna The functionality and durability of the lubricant is however contingent upon
the operating conditions. Where appropriate reduction factors must be considered.
