3. Operate the pump at low pressure until the hydraulic system has been
de-aerated.
4. For pumps with HF fluids: Run the pump for approx. one hour at low
pressure (30–50 bar).
DANGER Bodily injuries and property damage!
Incorrectly setting the pump in operation may lead to
unexpected and uncontrolled movements of the machine /
equipment and as a result may lead to bodily injuries or
property damage.
• Only trained personnel should be allowed to operate the
pump.
• Have the equipment manufacturer or operator assure that
no uncontrolled signals are being transmitted to the pump.
• Have the equipment manufacturer or the operator assure
that a pump malfunction (e. g. piston jam caused by crud)
is recognized so that a malfunction of the axle / machine /
equipment can be prevented.
WARNING Risk of Burns!
Pump parts run hot while in operation.
• Do not touch the pump while it is running.
WARNING Damage to Property!
Operating the pump without operating fluid will result in the
pump running dry and damage to the pump.
• Only start up the pump when the pump housing is
completely filled with operating fluid.
If the temperature of the operating fluid in the tank exceeds the pump
temperature by more than 25 °C, the pump should only be switched on in
short intervals of 1 to 2 seconds until it has heated up.
