DANGER
•
To remove the L-axis fixing jig, first confirm that the L-axis holding
power has been restored (that the brake of the L-axis motor has not
released).
Failure to observe this leads unexpected L-arm rotation at the
moment when the L-axis fixing jig is removed and it may result in
damage to machinery, death, or serious injury.
