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.

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 chain sprocket bracket and forward to
the threaded trolley shaft.
3. Use the second master link to connect the chain to the flat end
of the shaft (Figure 1). Check to make sure the chain is not
twisted.
