10 Handling the bucket
104
10.3 Operation of the retro bucket
• The retro bucket is adapted to dig the ground at a
level below the machine.
• The maximum digging force is obtained when the
angle between the bucket cylinder and the bucket arm
and the angle between the arm cylinder and the arm is
90°.
• For maximum effectiveness, handle the arm within
the range illustrated opposite : 45° forward and 30°
back.
• Do not move the equipment to the end of the cylin-
der run.
• To dig at a level above the machine, install the buc-
ket in the reverse position.

10.4 Digging trenches
1 = Parallel
• To increase the effectiveness of the machine, place
an appropriate bucket to dig a trench and position the
tracks in parallel on each side of the trench to be dug.
• To dig a wide trench, dig on the two sides then the
centre.
10.5 Loading
• To increase effectiveness, position the skip truck at
a location where the operator may view it and where
the machine's rotation angle is minimised.
• Load the earth from the back of the truck to facili-
tate loading and maximise the quantity of earth
loaded.
