Before transport 

Without parallel lifting 

With parallel lifting 

- Put the spindle in a fixed hole of the telescopic bar to lock 

during the transport. The operation is facilitated by using 
the second pin provided.   

- Set  the  grey  bush  so  as  to  have  the  frame  horizontal  in 

transport  position,  raise  the  machine  and  place  the 
second pin in fixe hole. 

- Raise the machine completely then fold it. 
- Make sure the automatic hook is securely locked. 
- Fix the safety fork on the cylinder rod. 
- Lower the machine to keep only about 2 to 3 cm distance 

between the safety fork and the cylinder. 
 

Always close the hydraulic safety valve before transport. 

Never lift completely the machine on transport to 

allow a suspension effect by  the accumulator. 

- Raise  the  machine  completely  then  fold  it  using  the 

hydraulic functions. 

- Make sure the automatic hook is securely locked. 
- Fix the 2 safety forks on the 2 cylinders rod. 
- Lower the machine to keep only about 2 to 3 cm between 

the safety fork and the rear cylinder. Put the fork in contact 
to the cylinder at the front.
