Fig. 6-1 

When maintaining the machine you often need to open or remove guards. For safety  

Fig. 6-2 

reasons all guards have been equipped with a lock. The lock ensures that the guard 
cannot be opened without using tools. Fig. 6-1 and 6-2 show the two different locking 
principles and the corresponding transfers which indicate and illustrate the locks on 
the machine. 
 

REPLACEMENT OF BLADES  

See description for replacement of blades in the rotor and the subsequent adjustment 
in the section REPLACEMENT AND ADJUSTMENT OF BLADES in chapter 4 
"ADJUSTMENTS".
