MANUAL LOWERING

MANUAL LOWERING

 

If the car lift cannot perform lowering operations because of power supply interruption, faulty hydraulic valves 

or electric trouble in the system, the lift can be lowered manually. For manual lowering operation (emergency), 

perform the following:

• Make sure there are no obstacles blocking the lowering phase; remember that the car lift may not be lifted 

again to remove possible obstacles.

• Disconnect main power supply.

• Remove manual lowering cap.

Note:  Manual lowering (emergency) operations should be preformed by authorized personnel specially trained 

for operating the car lift only.

• Loosen the manual operators (OM) (A1-B1)

1/2 turn.

• Emergency lowering has started; speed can be increased or decreased according to the opening of screws.
