9. Troubleshooting and relative solutions 

 

9.1 Basic machine 

a)     The quick couplings can't be connected: 

  Check if there's pressure on the hoses in case bring the pressure to zero ( see relative instructions ) 
  Check if the quick couplings are clean 

 

b)    The machine does not move in linear way: 

  The above mentioned situation could happen in case of clash or in case the machine with the pipe assembled in has been fiercely  
   moved.  If the damaged part can be located proceed to the substitution, however if the trouble still remain, kindly contact the  
  Customer Service  

c)     The nut/s  is/are seizure: 

         Replace the complete tie rod bolt   

d)   Oil leakage in the cylinders: 

Consult the 

Customer Service Dept.

 verify if it's necessary to replace the cylinders or just the gasket 

 
 
 
 
 
 

9.2 Facing tool

 

a)     The engine does not start: 

   Unplug the facing tool and check the electric connections and the safety micro-switch (shown 

by 

the arrow)

 

 

b)     The engine is burnt out:

 

   In case it's need to replace the engine the following operations must be done: 

-

 

Unplug the facing tool 

-

 

Unscrew the fixing screws 

-

 

Disconnect the safety microswitch 

-

 

Remove the engine by means of pulling in upper direction. In case of difficoulties, you 
can use a thin blade to detach the two flanges. 

c)   The blades do not remove material: 

Wear and tear of one cutting side enlighten the screws and turn the blades using the other side. 
Wear and tear of both cutting side of the blades replace with original spare parts. 
 
 
 
 
 
 
 
 
 
 

9.3 Hydraulic unit 

a)    The engine does not start: 

Check that the hydraulic unit engine is switched on 
The microswitch is damaged or wrongly adjusted 

-

 

To adjust the microswitch you must enlighten the screws show in the 

-

 

 figure below and bring the lever A to position A3. 

-

 

Move the microswitch towards the internal of the hydraulic until the  
 engine start and tighten the fixing screw.   

-

 

Check that in position A1the engine is switched off. 

-

 

In different case adjust the microswitch position again.
