WARNING
q
The use of the hand accelerator is allowed only under
the conditions specified below; use in any other condi-
tion may cause serious accidents.
The hand accelerator can be used only when the engine is
warming up and successively only when it is necessary to
work with the backhoe; it can also be used for certain mainte-
nance operations.
Idling position: pull the lever completely backward.
Max. speed position: push the lever completely forward.

The maximum speed position corresponds to 1900–
2000 rpm.
For a correct use of the lever, keep to the indications given on
the plate (C) applied inside the right dashboard.If possible,
avoid using the machine with the lever completely pushed for-
ward, since in this way consumption will be considerably in-
creased and the life of both the engine and the machine
shortened.
The plate (C) is characterized by two coloured areas, the
green area “A” and the red area “B”, referring to different en-
gine speeds:
q
Green area “A”: this area indicates an engine speed of
1700 rpm, which is the value recommended to the operator.
q
Red area “B”: this area indicates an engine speed up to
1900 ± 50 rpm, which is the maximum speed allowed for the
use of the backhoe.
The engine speed can be checked on the revolution counter
positioned on the right dashboard. See "3.3.2 pos. 3 - REV-
OLUTION COUNTER - HOUR METER".
