3.3.1.3 ADJUSTMENTS
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: 100 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 in-
crease visibility on the area in front of the machine.
(B) Inclination
Pull the lever (2) forward and adjust the seat backrest into a com-
fortable working position, 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 sus-
pension; to harden it, turn the hand wheel to a heavier weight.
When working on uneven surfaces, adjust the seat to a harder
setting.
