FINAL ADJUSTMENT AND REGULATING PROCEDURE
Minimum recommended door closing time is 6 Seconds for
doors opened to 90 degrees.
Use 1/8" hex (Allen) wrench to adjust valves as needed.
Closing and latching speeds:
Turn valves clockwise to slow down or counterclockwise to
speed up door movement.
Backcheck:
To regulate the intensity of back check action, turn valve clockwise
to increase or counterclockwise to decrease checking.
CAUTION: Set valve for slight cushioning effect; closer can be
damaged if the checking action is too abrupt. Never use
the backcheck as a door stop. Always use a door stop to stop
the door.
Delayed action feature (Optional feature on some models):
"Delayed action" provides slow door closing through the
delayed action range. Turn valve clockwise to slow down or
counterclockwise to speed up door movement.
