VALVE CHANGE 
If you have an equipment with number 4 in the third position of the reference (For example: HAM: _ _ 4_:, is it to say, 
HAM6441) you have an equipment with a valve AZ8400; for double acting cylinders. 
If you have a single acting cylinder and you want to use your powerpack with this kind of cylinder you must follow the steps 
below: 
 

1-  Remove the 4 screws which join the valve AZ8400 to the powerpack. 
2-  Lift the valve and separate from the lid of the powerpack. 
3-  A pressure inlet hole is located in the center of the lower side of the valve and you can locate 2 hexagonal screws 

on both sides of the valve.  

4-  One of these screws corresponds to the B outlet, located in the front of the valve; this is the screw which is 

allocated in the perpendicular to B outlet. 

5-  We have to remove this screw and we get the ball and the spring out. 
6-  Put them away in the bag supplied with the rest of the pieces. 
7-  Take the steel plug supplied with the powerpack in the plastic bag (Code: 15L0021) and put it in the B outlet. 
8-  Place the valve on the powerpack and put the 4 screws. 
9-  In this moment the equipment is ready to work with a single acting cylinder. (A Position: Advance, C Position: 

Maintains the load, B Position: Return of the cylinder) 

 
If you have an equipment with number 2 in the third position of the reference (For example: HAM: _ _ 2_:, is it to say, 
HAM6421) you have an equipment with a valve AZ8200; for single acting cylinders. 
If you have a double acting cylinder and you want to use your powerpack with this kind of cylinder you must follow the 
steps below: 
 

1-  Remove the 4 screws which join the valve AZ8200 to the powerpack 
2-  Lift the valve and separate from the lid of the powerpack. 
3-  A pressure inlet hole is located in the center of the lower side of the valve and you can locate 1 hexagonal screw on 

a side of the valve, and a threaded hole in the other side. 

4-  Take the hexagonal screw supplied in the plastic bag of the valve and place the spring, the retention ball and the 

copper washer. 

5-  Place the screw with the rest of pieces in the threaded hole. 
6-  Place the valve on the powerpack and put the 4 screws. 
7-  In this moment the equipment is ready to work with a double acting cylinder. (A Position: Advance, C Position: 

Maintains the load, B Position: Return of the cylinder) 

 
3.3 START UP 

 

¾

  Place the machine in the working zone in such a way as to ensure maximum stability. You should also make sure that the 

operator is sufficiently far away from the danger zone.  

¾

  The operator should check that no one is located in the danger zone and that the machine is in perfect working order and ready 

to be switched on.  

¾

 

Start the machine and operate according to the established method.  

¾

  In the event of problems of any type with HAE-type electrical control pumps, press the RED EMERGENCY STOP BUTTON, 

block the load mechanically if possible and resolve the problem before resuming operation.  

¾

 

With HAM-type manual control pumps, set the valve control to position ‘C’, stop the motor by pressing the red switch in the circuit 
breaker box and block the load mechanically if possible. Resolve the problem before resuming operation.  

¾

  Once you have finished, check the machine for any possible damage, disassemble it, clean it and store in a safe place.  

 
4. MAINTENANCE  

 

Make sure that the machine is switched off and not under pressure before carrying out any maintenance operation. 
Keep the pump clean and in good condition, especially as regards connections, threads, joints and quick plugs, etc. 
Use the tank indicator to monitor the oil level. If necessary, top up through the filling plug, using Larzep hydraulic oil (ref. AZ8902) 
Electrical connections and their periodic checks should be carried out by fully qualified personnel only. Any loose or damaged cables, 
etc. should be repaired or replaced immediately.  
If you are working in corrosive or aggressive environments, protect the machine accordingly and clean on a regular basis.  
Change the oil in the tank regularly – at least once a year if working in dirty environments and/or if the hoses are connected and 
disconnected frequently.  
To change the oil, remove the lid and clean both the tank and the filter, using materials that do not leave residue. When 
reassembling, use a new tank gasket. Fill the tank with Larzep oil, monitoring the quantity using the level provided.  
Do not dump used hydraulic oil. Collect and dispose of it according to the relevant waste disposal regulations.  
In the event of a failure or malfunction, all repairs should be carried out by specialist personnel using Larzep spare or replacement 
parts.
