Air
bleeding
To assure proper functioning of the jack, it is important to take any air out of it by applying the following
procedure:
1.
Remove the “Spring Buffers”.
2.
Lower the car (if already installed) so the jack is completely retracted. Always be sure that the cylinder
remains completely retracted.
3. Adjust the safety valve (BPS) (on the control valve of the power unit) from 25 to 50 PSI, so that
the system is pressurized without lifting the car.
4.
If the minimum of 25 to 50 psi can’t be reach, you can manually open the valve and add more BPS.
5.
Open the bleeder purge valve of the top section.
6.
Start the pumping unit and shut it down as soon as there is no more air coming out of the bleeder. Close
the bleeder to prevent unnecessary oil loss.
7.
Repeat these two steps for each section, beginning with the top one and finishing with the lowest.
8.
Run the cylinder about 5 complete strokes, both extension and retraction, to be sure of its proper
functioning.
9.
Repeat steps 2 to 6 to verify that there is no air in the cylinder.
If two people are bleeding the jack, it is possible to open all the bleeders at one since one person stays at the
power unit whereas the other closes the bleeder. A mechanic alone will have to bleed the sections one at a time.
It is possible that at some point your telescopic cylinder is desynchronized. Desynchronization
may be caused by
leaking seals or a malfunction of the check valve.
The venting procedure can resynchronize the telescopic
cylinder since it "resets"
t
he distribution of oil volumes between the sections.
