13.3 Controls to stabilize the vehicle
The controls conform with the safety directives and enable the operator to activa-
te the lateral extension of the outrigger supports and rams only from the side
where he can visually check the operation.
- Position lever D of oil diverter ( - S) on S.
Crane with outriggers manual extension and without supplementary outriggers
- Manual extension of the outrigger supports: See Paragraph 13.2.
- Outrigger ram descent; operate lever C.
Crane outrigger with manual or hydraulic extension and supplementary outriggers
For manual extension of the outriggers
- Manual extension of the outrigger supports: See Paragraph 13.2.
- Outrigger ram control; position the lever CD on the corresponding position
and then, activate the lever C.
For hydraulic extension of the outriggers
(!) ATTENTION (!)
Operation of the crane outrigger supports must be from the control station
on that side; it is not allowed to operate outriggers on the opposite side of
the vehicle due to unseen dangers. DE4491
- Put the lever A of the outrigger security check from the position of the fig. 13
to the one of the fig. 13a.
- Exit of the outrigger support; position the lever CD of the deviator on the corresponding
position and then, activate the lever Cof the distributor or of the double control.
- Outrigger ram descent; position the lever CD on the corresponding position
and then, activate the lever C.
(!) ATTENTION (!)
During the stabilising operations, for each outrigger ram, it is recommen-

(!) ATTENTION (!)
The complete extension of the outrigger supports is visually indicated by
the yellow triangles which are found at the end of the beam (and of the sup-
port if it’s supplied with extra double extension beams). (Fig. 13b).
The stabilization has to be carried out with care and gradually keeping the vehicle
in horizontal levelled condition to prevent springs overloads and chassis torsions.
To operate the crane controls, after having completed the descent and stabilisa-
tion manoeuvres,
- Position lever D of oil diverter ( - S) on .
Manoeuvres for re-entry of the crane outriggers and supplementary outrig-
gers within the overall vehicle width after crane use.
- Position lever D of oil diverter ( - S) on S.
Repeat by inverting the sequence of the operations.
(!) WARNING (!)
Keep hands clear of automatic stop device of the outrigger supports (Fig. 13).
(!) Always check that the outrigger supports, once in their rest position,
are locked in their seat by the safety devices, so as to assure the
impossibility of accidental movement. (Fig. 13).
