The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.
Risk of bursting due to incorrect opening of
pressurized equipment or components.
Pneumatic actuators are pressure equipment
that may burst when handled incorrectly.
Flying projectile fragments or components
can cause serious injury or even death.
Before working on the actuator:
Î
Depressurize all plant sections concerned
and the actuator. Release any stored en -
ergy.
Risk of personal injury due to preloaded
springs.
Actuators with preloaded springs are under
tension.
Î
Only open the actuator following the
instructions in this document. See
'Relieving the spring compression in the
actuator' in the 'Removal' section.
Risk of personal injury due to exhaust air
being vented.
The actuator is operated with air. As a result,
air is vented during operation.
Î
Wear eye and hearing protection when
working near the actuator.
Risk of personal injury through incorrect
operation, use or installation as a result of
incorrect information on the actuator.
After any adjustment or conversion work, the
details on the actuator nameplate may no
longer be correct. This applies to the bench
range, for example.
Î
Immediately renew any nameplates or
labels with incorrect or outdated infor-
mation.
Î
Add any new values to the nameplate. If
necessary, contact SAMSON to obtain a
new nameplate.
Risk of actuator damage due to excessively
high or low tightening torques.
Observe the specified torques when tighten -
ing actuator components. Excessive tighten -
ing torques lead to parts wearing out more
quickly. Parts that are not tightened far
enough may loosen.
Î
Observe the specified tightening torques.
Risk of actuator damage due to the use of
unsuitable tools.
Î
Only use tools approved by SAMSON.
