wheels of the vehicle must be discharged and free of load, that means:
the wheels must have left the ground (ground clearance).

The inclination of positioning of the Ruthmann-Steiger must be con-
trolled by means of the levelling indicator. The permissible inclination of
positioning must not be exceeded.

You have to take care that the vehicle is lifted warping-free.
Jacking must be effected in such a way that the stability of the Ruthmann-
Steiger is guaranteed at all times.
Danger!
By reducing stability a danger of tilting becomes exist-
ent! Stability can be reduced by:

Modification of soil conditions,

Sinking in of the jacks,

Leakage at the jack hydraulics.
The proper jacking must also be supervised during op-
eration. Especially e.g. after a break the extended stabi-
lizing jacks as well as the siting inclination of the Stei-
ger must be checked! Steiger operation must be
stopped immediately, if stability is no longer guaran-
teed.
Pre-condition:

The subsoil withstands the corresponding loads of the jacks,

Telescope is retracted,

Boom in boom rest.
Danger!
Danger of bruising during extension and retraction of
stabilizing jacks! Always supervise the jacks being ex-
tended or retracted!
Attention!
In order to avoid a damage of the jacks, they must al-
ways as first step be extended horizontally and after-
wards vertically extended. Retraction of the jacks is car-
