A Raise door, check alignment and see if it moves freely ( Figure 1 ). If door
appears out of alignment, binds, or does not move smoothly, contact a
Overhead Door Factory Authorized Dealer or dealer of your garage door for
repairs and adjustments to door mechanism.
B Raise door to 3' – 4' above ground and carefully let go. Door should stay
stationary. Slight movement is acceptable. More than slight movement
means door is out of balance. Contact a Overhead Door Factory Authorized
Dealer or dealer of your garage
door for repairs and adjustments
to door mechanism.

a note of whether it is a
sectional or a one-piece
door ( Figure 2 ).
