WARNING
q
Adjust the position of the seat before starting work or when taking the place of another operator.
q
Adjust the seat so that the control levers and the switches can be easily used by the operator seated
with his back against the backrest.
Adjusting the seat
(A) Longitudinal adjustment
The seat may be moved forward and backward.
Shift the lever (1) upwards, move the operator seat to the
desired position, then release the lever.
Longitudinal adjustment allowed: 140 mm.
Adjust the position of the operator seat according to the job to
be carried out. For example, when it is necessary to carry out
deep digging operations, make the seat slide forward in order
to increase visibility on the area in front of the machine.
(B) Inclination
Pull the lever (2) upwards and adjust the seat backrest in a
comfortable position to work, then release the lever.
During the adjustment operations, remain seated with the back
against the backrest. If your back is not in contact with the seat
backrest, the backrest can suddenly move forwards.
(C) Suspension
Rotate the hand wheel (3) positioned under the seat and adjust
it to the desired position.
Weight can be set between 50 and 120 kg.
Turn the hand wheel (3) to the lightest weight to soften the
suspension; to harden it, turn the hand wheel to a heavier
weight. When working on uneven surfaces, adjust the seat to a
harder setting.
