INSTRUMENTS AND CONTROLS
8 - HAND ACCELERATOR
DANGER
•
The use of the hand accelerator is allowed only under the
conditions indicated; use in any other condition may
cause 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 maintenance
operations.
Minimum speed position: pull the lever completely backward.
Maximum speed position: push the lever complately forward.
CAUTION
•
The maximum speed position corresponds to 1900÷2000
rpm.
If possible, avoid using the machine with the lever completely
pushed forward, since in this way consumptions will be consider-
ably reduced and the life of either the engine and the machine
will be longer.
For a correct use of the lever, keep to the indications given on
the plate (1) applied inside the right dashboard. The plate (1) is
characterized by two coloured areas, the green area “A” and
the red area “B”, referring to different engine rotation speeds:
•
Green area “A”: this area indicates an engine rotation speed
of 1700 rpm, which is the value recommended to the operator.
•
Red area “B”: this area indicates an engine rotation 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. 2 REVOLUTION COUNTER - HOUR COUNTER”.
