MAINTENANCE OF YOUR OPENER
Once a Month:
1. Test for reversal on a 1-1/2 inch high object or a 2 x 4 board laid flat on the floor (see “Important Test: Opener
Obstruction Sensing Feature”, page 18). If adjusting either the force or the limit of travel, retest the opener.
Failure to adjust the opener may cause serious injury or death.

Cautions on page 16). If it is unbalanced or binding, call a professional garage door service person.
