INSTRUMENTS AND CONTROLS
FUNCTIONING
3-20
(6) Travel levers (equipped with pedal)
WARNING
q
Before carrying out any manoeuvre with these levers,
the operator must seat in the work position and fasten
the seat belt.
q
Before moving the machine, make sure that the
sprocket (A) is positioned at the rear of the machine
and that the safety locks are engaged; if the turret is
rotated by 180°, the controls are inverted (see "HOW
TO MOVE THE MACHINE (3-67)" e "STEERING THE
MACHINE (3-72)").
q
Use the travel control pedals only when the machine is
moving. If a pedal is inadvertently pressed when the
machine is not moving or steering, this may move
suddenly and cause serious accidents.
q
When travelling or carrying out steering manoeuvres,
use the pedals with the maximum care.
q
When leaving the operator seat, always rotate the
pedals to the rest position, in order to avoid pressing
them by mistake.
These levers are used to operate the travel motors (right and
left) and control the forward and reverse travel according to the
movements indicated.
(a) FORWARD: levers pushed forward
(b) REVERSE: levers pulled towards the operator
N (Neutral): machine at rest.
REMARK
q
If the levers are in the forward or reverse position, the
sound alarm goes off to warm that the machine is moving.
q
When it is necessary to use the travel pedals, the opening
operation must be carried out by the operator while
correctly seated in driving position. After use, always rotate
the pedals to the rest position (closed).
NOTICE
When the safety lever is in the “locked” position, all the
movements are inhibited (see "Control locking safety lever
(3-17)").
