Before taking the machine into operation and to ensure the good functioning of the a-
pparatus, it is important that the following points are checked and correspond to the tech-
nical specifications as shown on the information plate and in the manual.
•
The type and weight of the sorting grab must conform to weight and machine class
of the intended excavator.
•
The oil flow and the pressure for rotating the
demolition
grab should be checked and
adjusted.
•
Beware: the return pressure of the rotating oil at a continuous level may be at a
max-imum of 25 bar, and only briefly (maximum of 10% of the working time) at 100
bar.
•
The oil flow and pressure of the pinching (opening and closing) of the sorting grab
needs to be controlled and adjusted.
•
Check if the hydraulic quick release hitch is in good order and screwed on firmly.
•
Check if the ball valves and valves are in the correct position
•
Check if the connecting pins between the excavator and the sorting grab are well
secured, as well as the wedge and the security pin of the quick release hitch system.
•
Ensures that the hoses have the correct length and are at no risk of interfering with
any of the moving parts. Also make sure they cannot wear or damage because of
contact with the grab or material that is moved by the grab.
