the opener sprocket and chain spreader (B). The opener
sprocket teeth must engage the chain. Continue

• Spin the inner nut and lock washer down the threaded
shaft, away from the trolley.
• To tighten the chain, turn outer nut in the direction shown.
As you turn the nut, keep the chain from twisting.
• When the chain is approximately 13mm above the base of
the T-rail at its midpoint, re-tighten the inner nut to secure
the adjustment.
Sprocket noise can result if chain is either too loose or
too tight.
When installation is complete, you may notice some chain
droop with the door closed. This is normal. If the chain
returns to the position shown when the door is open, do not
re-adjust the chain.
