DANGER
•
The machine must be parked on a level surface, with the equipment lowered to the ground.
•
When the coupling pins are removed or installed, chips may come off; always use gloves, goggles and
helmet.
•
The change of the equipment must be carried out by two persons, who must decide together the words
and signals to use during operations.
•
Do not use your fingers to center the holes, since they may be injured or even cut.
•
Before carrying out any operation on the hydraulic circuit, eliminate any residual pressure from the
equipment circuits (by shifting the controls more than once) and from the tank (by slowly loosening the
filling cap).
•
Clean immediately any area dirty with oil.
For the installation of the clamshell bucket, proceed as follows:
1 - Remove the standard bucket (see “3.12.5 CHANGING THE BUCKET”).

of the clamshell bucket delivery pipes.

7 - Mechanically lock the standard bucket push lever, in such a way as to stop the piston at the end of its stroke.
