Operation
Warning
Danger of crushing! Danger of shearing!
The piston rod moves fast and with great force. Body parts in the movement
range of the piston can be crushed or severed.
Do not reach into the movement range of the piston rod.
Do not place foreign objects in the movement range of the piston rod.
Observe the operating conditions.
Observe permitted limit values.

Maintenance and care
If used as intended, the product is maintenance-free.

Disassembly
Note
Disassembly only by qualified specialized personnel.
1. Disconnect the drive from the power supply (operating medium, electric power).
2. Loosen the mounting screws ( Fig. 5,
1
) and carefully remove the housing.
3. Disconnect electrical and pneumatic connection.
4. Loosen the mounting screws and remove the drive.
Loosening a hose
1. Press down on the disconnect ring (blue) of the push-in fitting and hold it down.
2. Carefully pull the tube out of the push-in fitting.
Cut off the damaged part before using the hose further.

Disposal
Observe the local specifications for environmentally friendly disposal.
Dispose of the product in an environmentally friendly manner. When doing this,
also take residual media into account (potential recycling of hazardous waste).

Fault clearance
Malfunction
Possible cause
Remedy
Piston rod does
not move in the
desired direction
Displacement encoder cable incorrectly connected
at positioning controller or DFPI
(e.g. connections at pin 1 and pin 3 interchanged).
Correct the connection
