Step 6: Levelling
Check the connection of the hydraulic and electrical system before levelling operation Review operation instructions and get
familiar with lift controls.
Attention: Level the platforms before connecting max height limit switch because if not, platforms may not rise to the highest position.
The operator needs to know clear which levelling valve controls which platform. This could be judged by the way that the oil hose was
connected or by trial raising or lowering.
Main platform is the platform which stay farther from the control unit.
Secondary platform is the platform which stay next to the control unit.
1) Open the door of the control cabinet. Check if the handle for the manually operating ball valve is at its default position P1. Should it
be not at P1, turn the handle to P1 and push the UP button until the main platform rises about 20 CM above the floor.
2) Turn the handle to P2 and push the UP button until the secondary platform rises about 20CM higher than the main platform. Push the
LOCK button to make secondary platform descend to its lowest position and don’t release the button until 5 more seconds later. Repeat
doing this for two cycles. After that push the UP button until the secondary platform rises to the same height as that of the main
platform (about 20CM above the floor).
3) Turn the handle to P1 and push the UP button to check the synchronization.
