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 backcheck 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" provides slow door closing through the delayed action range. Turn valve clockwise to slow down or counterclockwise to speed up door movement.
