14�2 Lubrication intervals and lubricants
Lubrication intervals
Perform service or inspection after approx� 8 years (refer to previous chapter 14.1).
After 50 operating hours or 1 year, regrease coupling shaft A, if available, at the greasing nipple.
For output shaft form A, ensure that the valve stem is greased separately!
These intervals are valid for normal load. When exposed to more intensive loads, the maintenance
intervals are reduced accordingly.
Actuators in high temperature version – add. version T09 – have to be checked for proper condition
by the SIPOS service every 2 years and wear parts have to be replaced!
Whenever the covers and hoods are removed, the seals must be inspected for damage. Replace
and regrease if necessary.
