ASSEMBLY STEP 5
Tighten the Chain
ALL MODELS
• Spin the inner nut and lock washer down the
trolley 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" (13 mm)
above the base of the 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.
NOTE: 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 pull the
emergency release handle to disconnect trolley
before adjusting chain.
