push-button panel to move the car up (by pressing the blue and white
buttons simultaneously) or down (by pressing the blue and black buttons
simultaneously) at speed (automatically selected as slow).
When stopping the movement, it is advisable to release the common blue

Stop the car with the roof surface level with the landing sill from where
you want to exit at the end of the work and/or inspections (of course, it
may not be the bottom floor for entering the pit).
IMPORTANT!

when the lift is in maintenance operation and stops the car moving up when it reaches it.
This contact is positioned to anticipate the impact of the counterweight on the buffer.
