The placing boom must not be raised until the machine has been
supported in accordance with the Operating Instructions. There is
otherwise a risk of the machine toppling over.
Swing out and telescope the support legs to their end positions in
sequence. Intermediate positions are prohibited to guarantee sta
bility. Exceptions are machines which have been equipped by the
manufacturer with a device which allows secure erection with a re
duction in support. Check the corresponding notes in this regard in
the operating instructions.
Do not carry out more than one movement at a time. If a movement
is stopped, the entire volume of fluid is available for the remaining
movements, and can increase their speeds. Depending on the de
sign, it may be the case that carrying out several movements at
once (as opposed to carrying out a single movement at maximum
speed at any one time) does not bring any advantage in terms of
time. Carrying out several movements at once requires an in
creased level of attentiveness.
Lock all supports mechanically, if this is provided for in the design.
Close all shut
− off valves in the support hydraulics. Leaks can cause
the supports to sink on one side.
