3 Risk analysis
a) The oil pump is working as pressure translator, thus improper output pressures cannot be
reached because the lower operating pressure is limited.
b) Improper absolute output pressures will be lock out by an additional pressure reducing
valve in the low pressure circle.
c) Leaks or duct cracks in the high pressure circle including no health risks for operators.
d) Duct crack cause a breakdown of the output pressure.
e) Is the determined output pressure not available after a short time, a damage of the
GERUPRESS is probably occurred. In this case, put the gadget out of operation,
disconnect the connect air tubes. Otherwise the gadget will get dirty by hydraulic oil.
f) Pay attention while closing of the cover. Prohibit
• damaging (operating level in „I“, cover cannot be closed)
• wounding
g) Sufficient lubrication of the oil pump and providing with hydraulic oil is ensured by
mounting the pump into the oil tank. In case of a pump leakage, the gadget and the
operator is protected by the casing of the tank.
BE CAREFULL: Disconnect high pressure tubes only while ventilation valve open.
4 How to exchange the oil at the high pressure pump
Oil can be removed by opening the oil screw
L
and by lifting the pump on the opposite side of the
pump.
BE CAREFULL: the oil starts running out as soon as you have loosened the screw!
Use oil admission socket
D
to fill in the oil.
Oil level gauge
E
indicates how much oil you have filled in. The pump should be
filled up to three
quarters (¾).
BE CAREFULL: Only use oils with the following specifications:
oil quality: anti-corrosion oil,
viscosity approx. 13 mm² / s = cSt / 20° C
We advise you to exchange the oil every three years because otherwise the pump might be
damaged due to residues of dirt.
