PROGRAM THE TRAVEL LIMITS AND FORCE SETTINGS
when moving UP or DOWN. The travel limit buttons are located
under the light cover (figure 1).
NOTE: The opener will MOVE AUTOMATICALLY after setting the
DOWN limit at step 6. A complete UP DOWN cycle is performed
in order to "Set the Force" automatically. If the door is
interrupted during this process, the force will not be set and
the process will have to be repeated.

point the opener will operate AUTOMATICALLY a complete cycle.

after this operation.

seconds.

Without a properly installed safety reversal
system, persons (particularly small children)
could be SERIOUSLY INJURED or KILLED by
a closing door.
• Incorrect adjustment of garage door travel limits will
interfere with proper operation of safety reversal
system.
• NEVER use force adjustments to compensate for a
binding or sticking garage door.
• After ANY adjustments are made, the safety reversal
system MUST be tested. Door MUST reverse on
contact with 40 mm high object laid flat on floor.
