NOTE
1. To avoid twisting the chain-cable / belt assembly, place the
holding hook
[K4]
on the rail and insert the long end
through the turnbuckle connector as shown.
2. Hold the threaded end of the turnbuckle with one hand while
turning the turnbuckle with the other to tighten the
chain / belt until the chain / belt is approximately 5/16”
(8mm) above the base of the rail at its midpoint.
3. Remove the “U” pin from the turnbuckle.
4. Attach sprocket cover
[J6]
by clipping it onto the motor unit.
You have now finished assembling your garage door opener.
Please proceed to the installation section.
During future maintenance, ALWAYS pull the emergency
release handle to disconnect the trolley before adjusting
the chain.
