Brake 

– testing the brake function 

Sheet 93

 

The brake must be capable of stopping the machine on a level road within 0.19 m 
per km/h. 
At a maximum speed of 8 km/h, this means that the maximum braking distance must 
not exceed 1.52 m. Check this after carrying out work at the brake system and as part 
of regular maintenance. 
 
This value must be achieved when actuating the brake tip switch S10.
