•
If the electric motor's motor protection switch is tripped, the cause must be
determined and eliminated. The motor can be started back up again after allowing it
to cool down.
•
The oil level drops when measurements are performed with the discharge
measuring container and when the pressure accumulator is filled. The oil level must
therefore only be checked when the discharge measuring container and the
pressure accumulator are empty.
•
If the power unit is moved, carried or pushed onto a trolley, the oil sloshes around in
the tank. As a result, a small amount of oil can escape via the vent filter in a time-
delayed fashion.
•
Connecting more than one hydraulic power pack in order to increase the delivery
rate is not possible because the varying fill-levels in the tanks cannot equalize
themselves.
•
The tank is emptied via the oil drain plug on the back of the oil tank. Catch and
dispose of the oil.
•
Limit system pressure to 6 MPa (60 bar).
•
Connecting the hoses
–
Never connect or disconnect the hoses when the hydraulic unit is running, or
while under pressure! Couplings must be connected when unpressurized.
–
Place the coupling socket vertically onto the coupling nipple.
The coupling socket and the coupling nipple must not be fitted askew.
–
After each disconnection, make sure that the couplings have closed themselves!
•
Before commissioning, make sure that all tank lines have been connected and that
all couplings have been fitted securely.
