5.10 Bleeding Trapped Air from the System & System Leak Test  

Torque  wrenches  and  hoses  are  not  always  completely  filled  with  oil  when  new.  For  safe  and  efficient 
operation, trapped air must be removed from the system. The following procedure must be carried out with 
a torque wrench connected to the pump, but 

NOT

 fitted on a bolt. 

For best performance, perform the below process each time hoses or tools are changed / swapped. 

To remove air from the system, proceed as detailed below: 

  Position the tool below the level of the hydraulic pump (as illustrated). 

  Connect the pump to an air supply and turn on the air supply. (The motor 

will not start until a pendant button is pressed). 

  Adjust the air regulator control (19) to between 5.5 and 7 bar, as shown on 

the air pressure gauge (16). 

NOTE: 

The tool may slowly perform a retracting motion. This is normal but 

does not always occur, it will depend on a number of factors. 

  Ensure the pressure relief valve (13) is fully open (wound anti-clockwise). 

 

Press the ‘Advance’ button on the control pendant (14) once, to turn on the pump. (See 

figure 5.6

)   

 

Press and hold the ‘Advance’ button (see 

figure 5.6

) on the control pendant (14). The tool may stay 

stationary or advance slowly depending on the relief valve setting. 

  Set the adjustable relief valve (13) to approx. 100 bar. The tool will advance to its full stroke. If the 

tool  retracts,  then  the  hoses  are  connected  incorrectly  and  need  to  be  swapped  over  at  the  tool 
couplers.  

  Release  the 

‘Advance’  button  on  the  control  pendant.  The  tool  will  automatically  retract  and  the 

gauge pressure will build up to between 80 & 90 bar. 

  Repeat the advance and retract cycle at least 10 times to fully purge the air from the system. 

  Visually inspect the system for leaks. 

(Low-Pressure leak test) 

With the air motor running the retract hose/s still contains 80 - 90 bar pressure.

 

DO NOT TOUCH. 

NOTE: 

When longer hoses are used (greater than 5m), the above procedure may not remove all 

the air from the system. In these cases, contact your Hi-Force representative for advice on pre-filling 
hoses with hydraulic oil. 

  Press  and  hold the 

‘Advance’ button again. While doing so, adjust the relief valve by turning the 

knob  clockwise  until  the  maximum  working  pressure  (700  bar)  is  reached.  The  pressure  can  be 
reduced by turning the knob anti-clockwise. The pressure setting can be locked at the desired value 
by tightening the wing nut under the adjusting knob clockwise. 

  Cycle the pump 2-3 times to full pressure making sure both the pump and connected tool/s operate 

smoothly through the entire pressure range.
