PRECAUTIONS TO BE TAKEN WHEN WORKING
51
2.4.3 HAND SIGNALS
WARNING
q
When it is necessary to position loads, make excavations or move the machine with reduced field of vi-
sion, the operator must be helped by another person standing on the ground and making signals to indi-
cate the manoeuvres to be carried out, according to the specific signals defined by the relevant
regulations.
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 neces-
sary, 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 sig-
nals.
The use of hand signals serves to direct the lifting, handling and positioning of the loads lifted by the work equip-
ment. 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 indica-
tions given below.
1 - LIFT THE LOAD VERTICALLY
With a forearm in vertical position and the forefinger pointing
upwards, rotate the hand making small circles.
2 - LOWER THE LOAD VERTICALLY
With an arm extended and the forefinger pointing down-
wards, rotate the hand making small circles.
