TMM3 (VIDEO FLUOROSCOPY) CHAIR WILL NOT GO DOWN
1.
TMM3 chairs are designed so the chair seat cannot be lowered while the upper portion of the chair
is rotated. The upper portion of the chair must be in line with the base for the chair to be lowered.
2.
If the seat cannot be lowered, rotate the upper portion of the chair then back to straight with the
base again and attempt to lower the chair.
3.
If step #2 did not fix the issue, find the limit switch under the seat of the chair and ensure that it is
not activated (the button is not pushed in).
4.
If the limit switch appears to be working properly, access the control box in the base of the chair
and unplug the cord in port #4.
WARNING!
This will disable the limit switch allowing the chair to
be lowered while the seat is rotated. Severe damage to the chair may occur while lowering the
seat while in the rotated state. This should only be disabled temporarily for troubleshooting
only!
5.
With port #4 unplugged, attempt to lower the chair slightly.
6.
If the chair goes down, the limit switch is faulty and requires replacement. Call or email technical
service for part number and price.
7.
Plug the cord back into port #4.
8.
If the column still does not go down, follow this link to “
