Thorough inspection
At least once per year a thorough inspection should be made and registered and these additional points checked:
All the jack stoppers, screws, and nuts should be checked and tightened it necessary.
All labels are legible.
Carefully check all of the exterior parts of the jack, no deformation, cracks or other damages allowed.
Pump up the jack completely until the safety release valve opens. There should be no oil leak.
Release the pressure of the pump and check the pillar to confirm the pillar is straight and without damages. The down movement shall be smooth
and without scraping.
When the jack is lowered the movement shall be stable and the jack must not be jammed. Slight vibrations are normal during the descend.
Add hydraulic oil
If the jack cannot be pumped up all the way, you may have to add hydraulic oil into the oil tank. The hydraulic fluid to be used must be in accor
-
dance with ISO VG22 or equivalent. Mixing of different fluids is prohibited!
Storage and transportation
Storage
Store the completely descended jack in a dry place, protected from corrosion and mechanical impacts.
Transportation
The operating handle (02) is only for operating the jack, not to carry the jack. When transporting the jack, it must not be dropped or thrown around
because it may cause damage to the jack. Therefore, the jack should be fixed before transporting to avoid shocks/impacts with other objects.
End of use/Disposal
Toe jacks shall be sorted/scrapped as general steel scrap, after the hydraulic oil has been removed.
Your POWERTEX distributor will assist you with the disposal, if required.
