INSTRUMENTS AND CONTROLS
79
If the lever is operated in directions that are inclined with re-
spect to the machine axis, simultaneous steering movements
proportional to the angle of inclination are obtained, since the
two hydraulic pumps corresponding to each single function are
engaged at the same time.
N - Neutral
A - Forward left steering
B - Forward right steering
C - Reverse left steering
D - Reverse right steering
CAUTION
q
Always travel at moderate speed, in order to obtain maximum precision and maximum efficiency during
work.
q
During work, the use of the lever must be proportional to the required effort and such as to obtain con-
stant engine speed.
q
Manoeuvre the lever smoothly, without abrupt movements and avoid counterrotations as much as pos-
sible, since these manoeuvres involve untimely wear of the tyres.
NOTE
q
The lever grip is provided with the horn, which must be used to warn the persons in the vicinity of the machine at
the beginning of work and in case of danger.
q
To inhibit all movements, lock the controls by lifting the safety bars in vertical position "3.3.5 pos. 1 - SAFETY
BARS").
