USING THE MACHINE AS AN EXCAVATOR 3.13.2 POSITIONING THE MACHINE FOR DIGGING OPERATIONS 128 DANGER • Before moving the equipment, make sure that no one is standing in the work area. • Before moving the equipment, make sure that the stabilizers are in the correct position. • Before raising the stabilizers, fold the equipment completely or rest it onto the ground. • Carry out all the possible movements and make sure that the control levers work properly. • 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 - Center the machine with respect to the digging line.

IMPORTANT • If this is not possible, because it is necessary to dig along walls or banks, move the backhoe sidewards (see “3.13.3 SLIDING THE BACKHOE UNIT SIDEWARDS”). 2 - Remove the boom antirotation 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 position until lifting the front wheels (2) in order to transfer the weight onto the bucket. Apply the parking brake. 4 - Make sure that the machine is in neutral and lock the front bucket control lever.

5 - Rotate the seat by 180°, fasten the safety belt, accelerate up to 15001600 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. 6 - Unlock the backhoe control levers and start work.
