3.12.2 ORGANIZING THE WORK AREA
DANGER
•
Always fasten the safety belt.
•
When the declutch push button is used, the machine keeps moving in neutral; to stop it, put on the
brakes.
•
The brake pedals can be separated to make them independent and reduce the steering radiuses; adopt
this solution only if it is absolutely necessary, at low speed and with lowered bucket.
•
Always warn the persons present in the work site, even if they are authorized, by means of the horn.
IMPORTANT
☞
•
The basic illustrations shown are those necessary for a correct use and exploitment of the machine;
the operator must get to know the controls, the described operating method, the use of the bucket po-
sition indicator and learn how to organize work in a free area, using low gears while seated in the driv-
ing position.
Thanks to this indicator, the operator always knows the position
of the front bucket with respect to the ground; when the bucket is
resting on the ground, this position is indicated by the return of
the rod (1) to the guide tube level (2).
If the machine is provided with automatic RETURN-TO-DIG de-
vice, the horizontal position of the bucket with respect to the
ground is determined by the sensor (3) positioned on the cylin-
der and is reached when the sensor does not detect the rod (1)
any longer. In case of malfunction of the device, check and if
necessary carry out the required adjustments.
To adjust the sensor, see “4.7.1.k ADJUSTING THE AUTOMAT-
IC RETURN OF THE FRONT BUCKET TO THE DIGGING PO-
SITION.”

If after a first inspection the area results to be uneven, encum-
bered with big obstacles or characterized by considerable height
differences, before starting work it is advisable to level the
ground as much as possible, both for the loader and for the vehi-
cles to be loaded.
This preliminary operations will make work quicker, ensure bet-
ter results and at the same time reduce the operator’s stress and
the straining of the machine components; furthermore, this will
considerably reduce the time necessary to load the trucks des-
tined to the transport of the material.
The area to be cleared from obstacles requires the use of a truck
positioned as indicated in the figure; for any other arrangement
the movements of the loader must be reduced as much as pos-
sible.
