2 Instructions for use
2.1. How to test a high pressure pump to see if it works
1. Check if the pressure gauges
F
and
I
are intact and control the position of the indicators.
Both indicators should be on zero.
2. Control the oil level (by locking at oil level controller
E
)
.
3. If the oil level is too low, fill in oil and follow these instructions:
3.1. Choose the quality of the oil according to the instructions on sign
H.
3.2. Open the oil admission socket
D
to fill in the oil by turning to the left.
3.3. Fill in the oil until the oil level controller
E
indicates that the tank has been filled up three
quarters (¾).
3.4. Now close the oil admission socket
D
by turning it to the right.
4. Close the pressure relief valve
B
and turn it to the right as far as it will go.
5. Now turn lever
A
(=start lever) into position II.
6. Connect the compressed air-tube to the compressed-air connection
G
.
BE CAREFULL: never use more than the maximum of 15 bar!
7. Pull and turn the pressure control valve
C
to the right as far as it will go (until you feel a
resistance).
8. Check the air pressure on the pressure gauge
I
(There should be an air pressure of at least
6 bar).
9. Put start lever
A
into position I.
10. The pump starts working and should build up a pressure of up to 2
.500 bar (if it doesn’t,
please check the air pressure).
11. When the oil pressure gauge
F
shows a pressure of 2.500 bar turn lever
A
back into position
II.
12. The pressure shown on oil pressure gauge
F
shouldn’t fall. This means that the pump is in
working order.
13. Open the relief valve
B
by turning it to the left.
14. The pressure shown on oil pressure gauge
F
now drops to 0 bar.
2.2. How to work with the high pressure pump
Start again with position 1. to 6.
Now pull and turn on the relief valve
C
to get the right oil pressure: 2 bar air pressure
≈ 500 bar oil
pressure. Then connect the high pressure tubes to the hose connection
K
.
Continue with position 9. to 14. Remove the high pressure tubes from the hose connection
K
when
you are finished.
BE CAREFULL: Hydraulic tubes can only be attached or removed if the relief valve E is
open. The oil pressure gauge A has then dropped to 0 bar.
