the door shaft, and as close to the door as possible.
Bracket Shelf Mount: The operator may be mounted either
above or below the door shaft.
NOTE: The optimum distance between the door shaft and
operator drive shaft is between 12 - 15 inches.
Install the Operator
Place door sprocket on the door shaft. Do not insert the key at
this time.
Place drive sprocket on the appropriate side of the operator.
Do not insert the key or set screw at this time.
Wrap chain drive around door sprocket and join roller chain
ends together with master link.
Raise operator to approximate mounting position and position
chain over operator sprocket.
Raise or lower operator until the chain is taut (not tight). Make
sure the operator output shaft is parallel to door shaft and
sprockets are aligned. When in position, secure the operator to
wall or mounting bracket.
Align sprockets, insert key into keyway, and secure.

sure the limit nuts are positioned between the limit switches
before proceeding with adjustments.
Remove cotter pin from nut on the clutch shaft. Back off clutch
nut until there is very little tension on the clutch spring. Tighten
clutch nut gradually until there is just enough tension to permit
the operator to move the door smoothly but to allow the clutch
to slip if the door is obstructed. Reinstall cotter pin when
finished.
