3.13.2 POSITIONING THE MACHINE FOR DIGGING OPERATIONS
WARNING
q
Before moving the equipment, make sure that no one is standing in the work area.
q
Before moving the equipment, make sure that the stabilizers are lowered.
q
Before raising the stabilizers, fold the equipment completely or rest it onto the ground.
q
Carry out all the possible movements and make sure that the control levers work properly.
q
If visibility is not perfect or there are ducts or lines of any kind, work at reduced speed and ask the as-
sistance of another operator.
1 - Centre the machine with respect to the digging line.
IMPORTANT
q
If this is not possible, because it is necessary to dig along walls or banks, move the backhoe sideward
(see "3.13.3 SLIDING THE BACKHOE UNIT SIDEWARDS").
2 - Remove the boom anti-rotation pin, introduce it in the apposite hole and release the boom from the safety
lock.
3 - Lower the front bucket (1) to the ground; force this movement until lifting the front wheels (2) in order to trans-
fer the weight onto the bucket. Apply the parking brake.
4 - Rotate the seat by 180°, fasten the safety belt, accelerate up to 1500–1600 rpm and lower the stabilizers (3)
until the rear wheels (4) are partially raised; this manoeuvre stabilizes the machine and avoids overloads on
the rear tyres.
5 - Inhibit the front loader control and the stabilizer control (only for machines equipped with mechanical backhoe
controls).
6 - Release the mechanical lock of the backhoe control levers and start work.
IMPORTANT
q
On machines equipped with backhoe servo controls, the movements of the levers can be enabled by re-
leasing the servo control locking button (see "3.3.2 pos. 12 - SERVO CONTROL LOCKING BUTTON").
