ASSEMBLING INSTRUCTION
1. ASTTACHING THE RES TO THE TRACTOR THREE POINT HITCH
a) Hook the machine to a crane using cables attached to the lifting points marked “Gancio“.
b) Lift and stabilize the machine at the level “H” (300 mm or 1 ft) from the ground and insert two blocks under
the base of the two stabilizers.
c) Back the tractor up to the machine, raise the three point hitch to the height of the machine connections and
connect the lower arms and the upper tie rod.
d) Install and adjust the bracket that will prevent the tractor hitch from moving.
2. INSTALLING THE HYDRAULIC PUMP
e) Connect the pump unit with multiplier to the tractor PTO.
f) Use the locking device supplied with the machine to prevent the pump from rotating.
g) Verify the oil level inside the multiplier following the instruction on page 12, point a).
3. ALERNATIVE METHOD TO ATTACHING THE RES TO THE TRACTOR
h) Instead of using the two blocks (point b), it is possible to use the stabilizers of the machine to lift and stabilize
the machine at the height “H” (300 mm or 1 ft). In order to do this the hydraulic pump must first be connected
to the PTO.

b) Lever “2” – 1° Arm and Bucket.
A = arm up – C = arm down – B = bucket opening – D = bucket closing.
c) Lever “3” – 2° Arm and Rotation.
A = arm down – C = arm up – B = right rotation – D = left rotation.
d) Lever “4” – Left stabilizer.
F = stabilizer down – E = stabilizer up.

BEFORE BEGINNING DIGGING
a) Verify the oil level inside the multiplier (see page 12 point a).
b) Grease the machine (see page 13).
c) Move to the working area.
d) Stop the tractor then engage the parking brake.
e) Switch on the PTO.
f) Lower the two stabilizers pushing the levers “1” e “4”.
g) Remove the safety stop that prevents the arm rotation.
TO BEGINNING DIGGING
a) Move people and animals at least 15 m (6 ft) away and be sure that there are no objects within 15 m (6
ft).
b) If it is necessary to shift the arm with respect to the tractor proceed as follows:
1) Unlock the 4 nuts that lock the arm to the main frame. If the machine is a RES30 turn the
lever to release the hydraulic lock.
2) Turn the arm fully in the direction of the shifting.
3) Open the bucket and put it into the ground.
4) Move the arm to shift the mobile frame.
5) When in position, lock the 4 nuts or turn the lever to engage the hydraulic lock.
c) Start the digging operation using the levers “2” e “3”.
AT THE END OF DIGGING OPERATION
a) Shift the mobile frame to the middle of the main frame.
b) Close the arm upon itself, turn it to the transport position and lock it with the safety pin.
c) Raise the two stabilizers completely.
d) Switch off the tractor PTO.
