2.9.7 MANUAL LEVELLING OF THE CONTROL CAR
The platforms are equipped with an automatic levelling device of the control car; this device
has been designed so that the basket floor remains always parallel to the ground indepen‑
dently from the arm movements of the platforms.
Anyhow, due to causes relative to possible blow‑by, it could be necessary to operate manual‑
ly to bring back the basket to its best position. To regulate do the following:
‑ Bring back the basket into the translation position by resting the third arm on the sup‑
port (only if you discover the problem when you are on the overhead control car);
‑ Loosen the safety screws by loosening first the lock nut (you
need two fixed 13 wrenches for this operation) until you free the
control (see photo);
‑ Raise the safety device against accidental activating of the con‑
trol. Act on it softly until you reach the levelling and also lowe‑
ring the engine rpm;
‑ Release the lever softly until the neutral point and bring back the safety screw into posi‑
tion. Finally tighten the lock nut.
Levelling the control car has been designed:
‑ As an exceptional manoeuvre in case a slight troubleshooting of the automatic levelling.
If the trouble was to repeat itself frequently have the control car checked in an authori‑
sed workshop;
‑ Activating the manual levelling control is only admitted from the control car; otherwise
the operator could suffer serious damages from the contact with the mobile parts of the
machine;
‑ Never do the levelling manoeuvre with aims different from the above‑described ones
(e.g. lifting objets, to increase the working range of the platform etc.). Such a use could
cause serious accidents even mortal.
