COUPLING COMPONENT ASSEMBLY

id031800805500

Warning
•  The engine stand is equipped with a self-lock mechanism, however, if the coupling unit is in a tilted condition, the self-lock mechanism could become inoperative. If the coupling unit unexpectedly rotates it could cause injury, therefore do not maintain the coupling unit in a tilted condition. When turning the coupling unit, grasp the rotation handle firmly.

1.  Assemble in the order indicated in the table.
