ASSEMBLY STEP 5
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 (Figure 1).
• When the chain is approximately 1/2" 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 too loose.
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 in Figure 2
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.
NOTE: You may notice loosening of chain after
Adjustment Step 3 (Test the Safety Reversal
System). Check for proper tension and readjust
chain if necessary. Then repeat Adjustment Step 3.
