(1) Visual Check
(a) For Versions ABCDE
ACTION RESULT
1 Make sure the unit is complete and undamaged, in particular check the absence of scratches, impact marks
and the state of surfaces on
connection orifices.
2 Make sure the weight and the
dimensions of the equipment.
3 Remove the protective cap from the connector and make sure the condition of electrical connectors.
4 Make sure the label identification.
5 Make sure that the eye end mount can be adjusted properly.
6 Make sure that the ball-screw has a protective sleeve or a protective jacket.
7 Make sure that the equipment part number and serial number are correct on the identification label.
