ASSEMBLY STEP 5

Tighten the Chain

• 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 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.
You have now finished assembling your garage door
opener. Please read the following warnings before
proceeding to the installation section.
