Possible faults and how to solve them:
1. Oil has entered the air system:
The most common reason for oil entering the air system is caused by wrong
handling or too high oil level.
Oil leaks caused by wrong handling require NO repair.
Has any oil entered the air system, it will come out through the silencer / filter of the air pump, in form of an
oil mist. If above rules are respected (See Warnings + Oil level), you don't need to do any more, the oil
from air system will come out by itself and the abnormal oil mist will slowly decrease until finally have
stopped.
2. The jack cannot lift to maximum height, and the pump runs continuously:
Check oil level and refill the oil tank if necessary.
3. The air pump operates slowly:
The air pump has not been lubricated enough, there is a problem with the air delivery.
Check if there is oil in the air lubricator, check if the lubricator is functioning correctly.
Check the air pressure, check if the air system is blocked.
4. The control valve cannot be moved or goes very slowly, even with pressure on the system:
The air supply is might be very watery and the lubricating film inside the valve has been washed away.
Inspect the water separator and lubricator on the air supply.
Loosen the fitting on the operating valve and fill the valve with oil.
Operate the valve many times without air connected.
Oil the jack more frequently.
5. In frosty weather: The jack will not pump:
There is too much water in the air supply, which has frozen.
Mount a water separator with lubricator on the air supply.
Change the oil of the jack, if there is water in it.
6. After extensive use, errors may occur because of worn seals:
Replace the old worn seals with new seals.
Destruction:
When the jack after several years is worn and must be dismantled, the oil must be drained off and legally
disposed of.
