1.     Tilt unit up 

on it’s 

nose. 
2

.

        Remove the 
e i g ht bolts 
securing the 

material head (ref# 23) to the hydraulic head (ref# 

51). 

3.     Remove diaphragm and examine large steel plate  ( front ) of the diaphragm 
assembly. Replace entire      assembly if sharp edges are evident.  
4.     Dismantle old diaphragm.  
5.     Continue at step 6, of assembly, if replacing entire diaphragm, or step 1 if 
installing a repair kit. 
 

Assembly 

 
1.     Slide large steel  plate onto the new screw provided. Screw should fit into the counter-sunk hole with 
        the flat side of hub facing away from the screw head. 
2.     THREAD one of the small nylon washers onto the screw, followed by the diaphragm pad and the 
        second small washer. There is no correct side to the pads, but it is important that the pads be threaded 
        on. DO NOT force pads over screw or leakage may occur due to the hole being enlarged.  
3.     Slide the smaller steel plate onto the screw, being careful that the beveled edge of the plate is against 
        the washer. The diaphragm must flex against the beveled surface. If the sharpe edge is against the 
        diaphragm, it will be cut by the sharp edge.        
4.     Tighten the jam nut onto the screw. A new nut should be used each time, as they are lock nuts and it is 
        imperative that the nut does not come loose.  
5.     Fill hydraulic head cavity with genuine H.E.R.O. LVO oil, before the new diaphragm is installed. 
6.     Place the new or repaired diaphragm assembly back into the hydraulic head, with  the large steel plate 
        facing up. Ensure diaphragm is resting within the hydraulic head’s recess.  
7.     Re-install the material head with the eight bolts. Torque to 30 ft. lbs. 
8.     Refill hydraulic oil tank and "PURGE" system following instructions on page 16.  
 
NOTE: The diaphragm will take on a wrinkled or puckered appearance almost immediately, when exposed 
to operating pressure. DO NOT be concerned by this. A diaphragm requires replacement when hydraulic oil 
appears in the spray material. Annual replacement is recommended as part of your preventative 
maintenance.
