9  Maintenance and repair 

9.1  General notes 

The  linear modules  are almost maintenance-free. Nevertheless, some 

maintenance work must be carried out to ensure an optimum operating 

condition of the linear module. 

9.2  Safety instructions for maintenance and repair 

 

 

 

 

Also observe the safety instructions in 

 Chapter 2 „Safety instructions“ in 

this manual. 

 

 

 

 

WARNING

 

 

Danger of injury due to improper maintenance! 

Improperly carried out maintenance activities can cause considerable 

damage to property and serious injury. 

 Only use qualified personnel to carry out the activities. 

 Always wear personal protective equipment when carrying out maintenance 

and repair work! 

 

CAUTION

When pneumatic systems are switched on, unpredictable movements may 

occur, causing injury or damage to property. 

 Only carry out work on the linear module when the system is depressurized 

and deactivated!
