Cylinder block and safety stop 

 

WARNING:

 Before performing maintenance work on the gun, make sure that the unit is 

at a complete standstill, that all of the buttons and the main switch are turned off and that 
the  unit  is  disconnected  from  the  main  power  supply.    The  gun  is  a  component  that 
works  under  pressure;  no  connection  must  be  opened  or  maintenance  work  done  on 
components subject to pressure until the pressure has been completely eliminated. 

 

Remove the side blocks and carefully separate them from the gun block. 
Clean the contact surfaces with a cloth dampened in gun cleaning solvent. 
Unscrew the bolt fixing the clamp on the rear of the gun. 
Remove the retaining ring from the cylinder using the snap ring pliers. 
Pull  hard  on  the  safety  stop  to  remove  the  whole  unit  from  the  cylinder.    Also  remove  the 
plunger spring. 
Check the state of the o-ring seal on the end cap.  Replace it if it is damaged. 
Apply a little grease to facilitate the placement of the o-ring. 
Loosen the two set screws on the safety stop. Remove the stop pin and the stop spring from the 
device. 
Remove the end cap from the stop pin. 
Remove  the  lip  seal  from  the  end  cap  and  replace  it  if  it  is  damaged.  Apply  a  little  grease  to 
facilitate the fitting. 
Pay attention to the correct installation of the lip seal: 

The seal lips must face forward. 

Fit the end cap onto the stop pin.  Slide the spring and the safety stop onto the stop pin. Tighten 
the two set screws making sure that they are perfectly aligned with the flats on the end of the 
stop pin.  Make sure that the blocking device is well-fitted. 
Insert the spring in the rear housing of the plunger. Insert the end cap into the cylinder bore by 
pressing until it passes the insertion groove of the retention ring. 
Fit the retention ring using snap ring pliers.
