EMERGENCY PROCEDURE FOR PLATFORM MANUAL LOWERING (POWER FAILURE):
By pressing the ‘UP’ button, the platforms will rise. Platforms will stop climbing when
they reach the upper limit.
By releasing the ‘UP’ button, the oil pump stops immediately and the platforms stop
rising.
By pressing the ‘DOWN’ button, the platforms will start to descend.
The platforms will stop descending to a height of about 200-300mm, when they reach
the lower limit switch.
By releasing the «DOWN» button and by pressing «LOCK SEC. DOWN», the pedals will
go down to the closing position.
During up and down operations of the lift, if the platforms are not on the same level, the
photoelectric alignment device will turn off immediately and will only activate after the
platforms are aligned at the same height.
If during the ascending or descending stages of the lift, operating malfunctions occur, press
the «EMERGENCY STOP» button to stop the entire operating circuit and stop any other
operation.
After completing the installation and making the lifts calibration, the right platform is lower
than the left one due to the air still present in the oil cylinder. When performing the oil circuit
setting operation, the bridge must not be placed in operation and no weight must be placed
on the platform. The adjustment process must be carried out as described in Chapter 5 «Oil
Pressure Adjustment».
During the manual lowering of the platforms keep close
observation of the vehicle placed on the deck until the
operation is completed. If there are anomalies during the
process, immediately close the hydraulic circuit safety valve.
The manual lowering process takes place as follows:
Place the «MAIN SWITCH» button on the «OFF» position
(do not remove the power from the power supply).
Open the rear door of the control unit and look for the
descending electromagnetic valve A.
Unscrew slowly the RED oil valve; you will notice that the
platforms will start to descend.
Always check the correct leveling of the platforms during
down operation.
After lowering the platforms, immediately tighten the lower
valve screw.
The manual lowering process of the footrests is now
completed.
