DMSP−... / MAS−...
7 Operation
Please note
Extreme conditions reduce the service life
of the DMSP−... / 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.
If pressure is applied to one side and ex
hausted on the other side (rinsing), the
thermal stressing of the components can
be reduced and the service life of the
Fluidic Muscle thereby increased (not with
MAS−...−MC.. and DMSP−...−CM).
Check the DMSP−... / MAS−... for signs of aging at the following intervals.
