Disassembly of actuator
Step 1
Manual actuator
The manually operated actuator can not be dismantled.
The reason is that the lifetime is very long due to few activations
compared to the pneumatic actuator.
NOTE:
In the event that you need to dismantle the actuator, this can be
done safely as there are no springs inside.

Step 2
Pneumatic actuator
Always release compressed air before dismantling the actuator.
The pneumatic actuator can be dismantled by using a special tool. (The part no. is shown on the spare part).

A = Tool to lock the actuator rod to avoid breaking the “spring guides” inside the actuator.
B = Tool to loosen actuator cap (spanner wrench)
C = Distance piece
Type A-A:
In the pneumatic actuator type A-A there is no spring inside the housing.
The actuator can only therefore be opened by using the special tool “B”.
It is not necessary to use special tool “A” and “C”.
