Cab driving position adjustment
With cab under static load condition, check length X
2
of front shock absorbers (7) and length X
1
of rear shock absorbers (4).
!
By static load it is only meant the load that is determined by the type of cab fitting.
Such length as measured between the center distances of shock absorber eyelets, must result to be :
X
1
=
400 mm
X
2
=
380 mm
If different values are found, rotate the regulator (3 and/or 8) of relevant shock absorbers with a suitable wrench.
!
The regulator is provided with 5 marks, each mark, starting from the central reference mark, corresponding to a length
shift of 4 mm.
