13.1. Open both screws

on the injector body.
13.2. Turn the injector body 90° (right or left) and tighten with a screw.
13.3. Now you can open injection nozzle fixed in the injector body with included special key.
ATTENTION: High pressure hose may only be connected or removed by opened bleeder
valve E. Display unit A at the same time dropped to 0 bar.
3 Risk analysis
1. Through intermittent control of the pressure on the low pressure point, the pump impedes
starts with incorrect pressure on the high pressure point.
2. Incorrect absolute pressure (High pressure point) will be excluded by application of an
additional pressure limiting valve in the pressure circulation (low pressure circulation).
3. Leakage or cable link at the high pressure system are not combined with direct healthy risks
for the operator.
4. Cable links cause a breakdown of pressure on the high pressure point.
5. If GERUTEST cannot build the required pressure within short time the device is defect. The
device has to be stopped, otherwise the available oil will be extracted through continuous
operation to the body chamber and will lead to unnecessary fouling.
6. Adequate lubrication of the pump and the supply with Hydraulic-oil will be achieved by
installation of a pump in the oil tank. During pump leakage the working room is protected
through the tank walls of emergent oil.
ATTENTION: High pressure pipes may only be detached by unclosed bleeder valve.
4 Oil change at high pressure pump
By opening the oil drain plug
L
and slowly lifting on the opposite side of the device the oil can be
drained.
ATTENTION: Oil will flow immediately after loosening the screws!
The filling of the device will be carried out by the oil filler neck
D
. Oil level can be read by oil level
gauge
B
. When filling the device should be filled ¾.
ATTENTION: Only use oil with following:
Oil quality: anti-corrosive oil,
viscosity about 13 mm² / s = cSt / 20° C
It is recommended to do an oil change every 3 years otherwise it can cause damage on the pump
through dirt.
