Before carrying out any manoeuvre with this lever, the operator must be seated in the work position with
fastened safety belt; before any manoeuvre he must perform the operations described in"3.13 USING
THE WORK EQUIPMENT".
q
When travelling on roads, always lock the equipment control (see "3.3.5 pos. 8 - EQUIPMENT CONTROL
LOCKING LEVER (IF INSTALLED)").
q
Before leaving the operating position, lower the equipment to the ground and lock the safety bars (verti-
cal position), then stop the engine.
q
Failure to comply with these instructions may lead to serious accidents.
CAUTION
q
The self-leveling system is operated automatically only when the loader arm is lifted with loaded bucket.
When the arm is in the lowering phase the system cannot be operated.
q
At the maximum height the self-leveling system keeps the bucket partially folded to prevent the material
from falling out of the bucket itself.
The equipment control lever (3) is positioned on the operatorís
right and controls the loader arm lifting and lowering and the
bucket dumping and folding functions.
The following diagrams show the basic manoeuvres and the
possible combined manoeuvres.
