STOP 

 

With assembly, operation and maintenance of the brake it has to be made sure that the enti-
re drive train is secured against accidental switch-on. You may be seriously hurt by rotating 
parts. Please make absolutely sure to read through and observe the following safety indica-
tions.

 

  All operations on and with the brake have to be performed taking into account "safety first". 

  Make sure to switch off the power pack before you perform your work on the brake. 

  Secure the power pack against accidental switch-on, e. g. by providing warning signs at the place of switch-on 

or removing the fuse for current supply. 

  Do not reach into the operating area of the brake as long as it is in operation. 

  Secure the brake against accidental contact. Provide for the necessary protection devices. 

  Make sure that the overall brake/hydraulic system is depressurized during maintenance operations. 

 

 
You may only assemble, operate and maintain the brake if you 

  have carefully read through the operating/assembly instructions and understood them 

  are technically qualified and specifically trained 

  are authorized by your company 

The brake may only be used in accordance with the technical data (see chapter 1). Unauthorized modifications on 
the brake design are not admissible. We will not assume liability for any damage that may arise. In the interest of 
further development we reserve the right for technical modifications. 
The 

brake type L light-xxx A-xx-xx

 described in here corresponds to the technical status at the time of printing 

of these operating/assembly instructions. 
 

 

 
The brake is delivered in preserved condition and can be stored in a closed, dry place during 12 months. 
With favourable storage conditions its properties remain unchanged for up to 12 months. 
If the brake is stored over a longer period exceeding 12 months as well as after each transport the corrosion pro-
tection needs to be renewed and the brake has to be activated over the full braking distance in order to prevent 
the gaskets from sticking together. 
 

 

 

The storage rooms must not include any ozone-generating devices like e. g. fluorescent 
light sources, mercury-vapour lamps or electrical high-voltage appliances. 
Humid storage rooms are not suitable. 
Please make sure that condensation is not generated. The best relative air humidity is less 
than 65 %. 

 

 

 

 

In order to avoid any injuries and any kind of damage please always make use of proper 
transport and lifting equipment. 

 
The brake is packed differently each depending on number and kind of transport. Unless otherwise contractually 
agreed, packaging will follow the in-house packaging specifications of KTR.
