The machine should be extended and lowered to the ground. It is essential that all 
cylinders are depressurised.  
 
 

 

Beware of the weight of any given part when removing or disassembling. All parts 
must be supported or lifted to avoid danger of falling. 

 
Disconnect hydraulic hoses and cylinders and drain oil. Collect oil in container to 
avoid pollution. Send oil and hoses for safe disposal.  
 
All iron used in the machine can be recycled.
