ASSEMBLY STEP 4
Tighten the Chain
• 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" (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.
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.
You have now finished assembling your garage door
opener. Please read the following warnings before
