Shock at direction A (see the the right figure), and
check the ball head pin.
See "Maintenance data & explanation" for reference.
If the torque A is not in the required range, replace the ball head pin.
Check the ball head pin for its driving torque B.
See "Maintenance data & explanation" for reference.
If torque B is not in the required range, replace the ball head pin.
Check the ball head pin vertical clearance C.
See "Maintenance data & explanation" for reference.
If the clearance value is over than the required range, replace the ball head pin.
Check the dust proof for damage.
Note:
If the ball head pin is new, and the dust proof is damaged, replace the dust proof under the quide of the pro-
