Disconnect the electrical and hydraulic parts. 
Where the machine is to be scrapped, do not dispose of potentially polluting parts in the environment, following 
local regulations for their correct disposal. 
At the time of the machine being scrapped it is necessary to remove and destroy the identification plate and all 
other relative documents. 
 

3.5 

Regulation 

 
The only parameter which can be modified is the pressure; to modify the value increase or decrease the pressure 
of the command fluid. 
 

3.6 

Maintenance 

 

!

  

 Locate the machine in conditions which facilitate easy access. 

 

Utilise individual protection to avoid contact with mineral oil or grease 

 

Having undergone rigorous testing by ourselves, the pump does not require any further maintenance. The use of 
lubricants free from impurities is recommended and the periodic careful cleaning of the component parts of the 
pump. 
Disassembly must be effected in the following manner: 
 
1.

 

disconnect the tubing attached to the pump. 

2.

 

remove the fixing screws and the tank and relative cover. 

3.

 

remove the suction filter and the relative valve. 

4.

 

unscrew the cylinder paying 

particular attention

 to the loading of the springs; the component parts of the 

pump unit can then be disassembled. 

5.

 

remove the screws which retain the flange so releasing the complete pump unit. 

 
In  this  way  all  component  parts  of  the  pump  unit  can  be  removed  allowing  the  disassembly  and  cleaning  of  the  
release and suction valves. 
All pieces should be washed in petrol and lubricated prior to reassembly. 
 
The following should be checked periodically: 
 

VERIFY 

WORK CYCLES 

The state of lubrication 

100 

The oil level 

200 

The cleanliness of the suction filter 

400 

That the tank is clean and the bottom free from deposits 

600 

 
The  machine  does  not  require  any  special  tools  to  carry  out  checks  or  maintenance  tasks,  However,  it  is 
recommended that only tools suitable for the tasks and in good condition should be utilised (DPR 547/55) to avoid 
injury to persons or damage to machine parts. 
 

3.7 

Repairs 

 
The following diagnostic table indicates the main anomalies which may be encountered, the probable causes and 
possible solutions. 
The anomalies shown are: 

 

the pump fails to deliver sufficient oil or no oil at all; 

 

the pump fails to deliver oil at the prescribed pressure; 

 

failure to release line pressure (only on systems with volumetric valves). 

 
In case of doubts and/or problems which cannot be resolved do not attempt to disassemble parts of the machine 
but contact the Engineering Department of DROPSA S.p.A.
