Description of Issue
When the head is cranked all the way up and fails to lower when using the crank.
Possible Causes
Causes include: the head is raised to the top of travel and stuck.
Troubleshooting Steps
- Check that the head is not already at the top of its travel (up against the side stabilizers). Cranking the head beyond its highest useable height can result in it locking in a position where the head crank cannot lower it. Releasing from this locked position it is very easy. The right side threaded leadscrew needs to be manually turned and can be accessed from the inside of the machine. There is a hole in the leadscrew just above the traction belts. Insert an Allen wrench or similar tool and rotate it in the clockwise direction to unlock it.
