Without a properly installed safety
reversal system, persons (particularly
small children) could be SERIOUSLY
INJURED or KILLED by a closing
garage door.
• NEVER learn forces or limits when
door is binding or sticking. Repair

travel limits will interfere with proper
operation of safety reversal system.

the safety reversal system MUST
