INSTALLING THE CHAIN
1. Dispense a few inches of
chain from carton and fasten
to trolley with a master link
from the hardware bag.
(Figure 1).
• Push pins of master link
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.
2. To prevent the trolley from jamming against the opener
during operation, position trolley 5 to 15 cm from the
stop hole as shown. Then dispense the chain around
the opener sprocket (Figure 1). Make sure the sprocket
teeth engage the chain.
• Proceed around to the pulley bracket and forward to
the threaded trolley shaft.

flat end of the shaft (Figure 1). Check to make sure the
chain is not twisted.
