Please note
Extreme conditions reduce the service life
of the MAS−... .
S Take into account the fact that the fol
lowing factors can considerably reduce
the service life C (see diagram Fig. 12):
increasing contracton h and
additional increasing mass m,
increasing ambient or operating
temperatures.
The compression heat produced during
operation can be reduced with bilateral
pressurization (flushing) (only with
MAS−...−MO..).
Check the MAS−... for signs of aging at the following intervals.
