5.1  Generating pressure

After the purging the hydraulic lines, pressure can be created with the hand pump. 

With increasing back-pressure in the system, the pumping process becomes increa-

singly difficult.

WARNING!

 There is a risk of injury if the maximum pressure is exceeded!

Note the maximum permitted pressures of the individual components in the measure-

ment device. If the limit values are exceeded, it may lead to material damage and 

injuries. 

â

 Do not continue to pump under any circumstances if the maximum permitted  

 

pressure has been reached or an exceeded measuring range is displayed.

CAUTION!

 Material damage to test item!

Adhere to the maximum pressure of the test item!

Only create an admission pressure with the hand grips that is lesser than the 

necessary testing pressure. Following this carefully increase the pressure using the 

fine adjustment valve.

Notes on operation
Please observe the following notes concerning the operation of the hand pump:

●  Ensure that no air is suctioned during the pumping process. 

  – To ensure that this does not occur, hold the hand pump at a slight angle so that  

  the suction nozzles are always surrounded by hydraulic liquid.

●  Ensure that there is sufficient hydraulic liquid in the reservoir. 

  – If necessary, refill the hydraulic liquid. This must also be ensured during depres- 

 surisation 

●  For small hydraulic volumes and well-ventilated systems, a higher pressure is al-

ready built up with a few movements of the pump.

  – Ensure that the maximum permitted pressure is not exceeded. 

●  From approximately 400…500 bar, a lot of strength is required for pumping from the 

initial position of the handles.

  – Increase the pressure using the fine adjustment valve and note the following tip.
