8.5 MANUAL EMERGENCY LOWERING
If there is no power or the control unit is damaged, lower the lift manually to its initial position as
follows:
• Padlock the power switch;
• Operate the emergency hand pump (fig.19 - 1) to raise the lift a little bit to clear off the
mechanical safeties;
• Keep pressing the emergency button (fig.20 - 1) on the solenoid air valve in the control unit;
• Unloosen the emergency screw (fig.19 - 2) anti-clockwise to lower the lift. Screwing or loosing
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.
