To prevent possible SERIOUS INJURY or DEATH from a falling 
garage door:
•  If possible, use emergency release handle to disengage 

trolley ONLY when garage door is CLOSED. Weak or broken 
springs or unbalanced door could result in an open door 
falling rapidly and/or unexpectedly.

•  NEVER use emergency release handle unless garage 

doorway is clear of persons and obstructions.

•  NEVER use handle to pull door open or closed. If rope knot 

becomes untied, you could fall.

•  

Thread one end of the rope through the hole in the top 
of the red handle so “NOTICE” reads right side up 
as shown. Secure with an overhand knot at least 
1" (2.5 cm) from the end of the rope to prevent slipping.

•  

Thread the other end of the rope through the hole in the 
release arm of the outer trolley.

•  

Adjust rope length so the handle is 6 feet (1.8 m) above 
the floor. Ensure that the rope and handle clear the tops 
of all vehicles to avoid entanglement. Secure with an 
overhand knot.

NOTE: If it is necessary to cut the rope, heat seal the cut 
end with a match or lighter to prevent unraveling.
