9.2.3 Brake at rear-wheel drive

If the machine has an X-AC drive, the rear 
wheel brake must also be unlocked. To do 
so, push the lever at the rear on the right 
side of the machine, figure 9.4 -A from 
right to left until it engages.
Indication appears on the multifunction 
display Fig. 9.4 -B when the rear wheel 
brake is taken out of service. 
The machine can no longer be driven!
Disassembly is in reverse order.
