personnel and damage to material assets: 

 

Only use the product as directed in this manual. 

 

Never put the product into service if there is evidence of visible damage. 

 

Never put the product into service before fully completing installation and 
commissioning. 

 

Do not carry out any modifications to the product. 

 

Only use authentic Kobelt spare parts. 

 

Observe all local regulations, directives and laws during the installation of this product. 

 

All installation, commissioning and maintenance work must only be conducted by 
qualified personnel.  (For the purpose of this manual, qualified personnel are persons 
who are familiar with the assembly, installation, commissioning, and operation of the 
product and who have the qualifications necessary for their occupation.)

1.2.3

 

Hazards 

 

Equipment Starts Automatically:

  

Brake systems frequently are controlled remotely and may activate suddenly 
causing bodily harm. Ensure all power sources are locked out prior to 
performing work.

 

 

 

Brake Actuators Contain Compressed Springs:

  

The brake actuators contain springs that are under compression even when 
the brakes are not pressurized. The springs will release suddenly if 
disassembled incorrectly posing a risk of serious injury or death. Do not 
attempt to disassemble the actuators without clear work instructions and 
training.

 

 

 

Pinch Points: 

Brakes contain numerous pinch points which can cause serious injury. 
Ensure all power sources are locked out prior to performing work.

 

 

 

High Pressure Fluids:

  

Kobelt lever brakes use high pressure hydraulics. Ensure all pressure is 
exhausted and the pressure source locked out prior to performing work.

 

 

 

Hot Surfaces:

  

Disc brakes are capable of making the surfaces of the brake disc dangerously 
hot when burnishing or during braking events. Ensure the disc is adequately 
guarded to prevent inadvertent contact with the disc.
