3.10 LIFTING THE MACHINE
DANGER
•
To lift the machine, the cables and the upper lifting bar
used must be properly sized; do not use worn cables or
cables with broken strands.
•
Do not lift the machine before the operator has got off and
make sure that there is no one around before lifting it.
Lift the machine by proceeding as follows.
1 - Rotate the upper structure so that the blade is behind the op-
erator and raise the blade completely.
Extend the bucket, boom and arm cylinders completely and
make sure that the control levers are in neutral.
2 - Swing the boom to the central position and engage the con-
trol pedal safety device.
3 - Shift the safety device lever to the lock position and stop the
engine.
4 - Insert a metal or nylon rope in the two holes provided on the
blade ends and in the boom hole. Fix the ropes with appropri-
ate locks or safety pins.
5 - Connect the ropes to the upper lifting bar as indicated in the
figure.
IMPORTANT
☞
•
Always use the three coupling points provided for the lift-
ing operations.
6 - Lift the machine slowly until the ropes are stretched and
make sure that the fastenings are correct before lifting the
machine definitively.
CAUTION
•
When lifting the machine, make sure that it is correctly
balanced and that it remains in horizontal position during
the lifting operations.
•
Do not lift the machine with swung boom or without using
the lifting bar.
