SIGNALMAN'S SIGNAL AND SIGNS 2
q
Set up signs to inform of road shoulders and soft ground.
q
When it is necessary to position loads, make excavations or move the machine with reduced field of vision, the
operator must be helped by another person standing on the ground and making signals to indicate the
manoeuvres to be carried out, according to the specific signals defined by the relevant regulations.
HAND SIGNALS 2
WARNING
q
No movement or operation should be carried out if the signals have not been clearly understood by
the operator and the signalman.
q
When additional instructions different from those defined by the manual signalling system are
necessary, these must be agreed upon by the operator and the signalman before starting the job.
q
Only one person must be entrusted with making signals.
q
The operator must make sure that the signalman is always within his field of vision and follow all his
signals.
The use of hand signals serves to direct the lifting, handling and positioning of the loads lifted by the work
equipment. Hand signals can also be used during digging operations or when the machine travels, if the field of
vision of the operator is reduced. The direction of movement of the hands and arms in relation to the machine must
define the signal, independently of the position of the signalman. Hand signals must be performed following the
indications given below.
