8.3 MANUAL EMERGENCY LOWERING (ref. fig. 32)
In case of no electric power or power unit failure, lower the loaded vehicle manually to its initial
position as follows:
• Padlock the power switch;
• If the mechanical safeties are engaged, raise the
lift enough high using a hydraulic jack or the
emergency hand pump (1/fig.32, if ordered
with the lift) to clear off the safeties.
• Keep pressing the emergency button (2/fig.32)
of the air solenoid valve to avoid the safeties
from engagement.
• Unscrew the emergency screw (3/fig.32) anti-
clockwise to lower the lift. Screwing or
unscrewing the screw can reduce or increase
the lowering speed.
• Retighten the emergency screw by screwing it
clockwise after lowering the lift completely.
After manual lowering of the lift, reset ordinary operating conditions. Lift cannot
be raised if the lowering valve is opened.
