master link from the

bar through chain link
and hole in front end of trolley.
• Push master link cap over pins and past pin
notches.
• Slide clip-on spring over cap and onto pin notches
until both pins are securely locked in place.

chain around the opener sprocket (Figure 1). Make
sure the sprocket teeth engage the chain.
