STEP 3 It is highly recommended to wear protective eyewear during the following filling and bleeding procedure.
To fill the system with oil, hold the lever of the switch in the position that connects the air supply to port number 2 (DOWN position).
In this position, compressed air is directed to the top connector of the pump unit which will push the internal air piston backwards (or roof down). At the same time, this will put pressure on the oil tank so the oil will start flowing through a bypass to the cylinders.

It can take a few minutes to completely fill the hydraulic circuits.
After filling, hold the lever in the UP position (air supply to port number 4) ; the pistons of all cylinders will now rise and the roof will go up:
If all pistons extend fully, proceed to step 4.
Ì
Ì If the pistons don’t reach maximum height, repeat the filling procedure by holding the lever in the DOWN position again.
The roof will descend and the system will start filling the hydraulic circuits again. After a few minutes, check once again if the roof rises completely by holding the lever in the UP position.
Ì If the roof goes up further than before but not completely, repeat the filling procedure.
Ì If the roof doesn’t go up further than the first time, check the oil level in the reservoir by flipping the lever in the DOWN position again to let the roof descend.
When the roof is completely down, check the oil level in the reservoir (continued on next page)
