PRECAUTIONS TO BE TAKEN DURING WORK
39
2.4.3 HAND SIGNALS
WARNING
q
When it is necessary to position loads, make excavations or move the machine with a reduced field of vi-
sion, the operator must be helped by another person (signalman) who should stand on the ground and
give signals to indicate the manoeuvres to be carried out according to the specific instructions provided
for by the relevant regulations.
q
No movement or operation may be carried out if the signals have not been clearly understood by the op-
erator and the signalman.
q
When additional instructions different from those defined by the hand signalling system are necessary,
these must be agreed upon by the two operators before starting the job.
q
Only one person must be entrusted with giving 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 given following the indications be-
low.
1 - LIFT THE LOAD VERTICALLY
One forearm in vertical position and forefinger pointing
upwards: turn the hand making small circles.
2 - LOWER THE LOAD VERTICALLY
One arm down and forefinger pointing downwards: turn
the hand making small circles.
