Tighten the Chain & Cable

 

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 1/2" 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.

NOTE: During future maintenance, ALWAYS

)ull the emergency release handle to disconnect trolley before adjusting chain.
