CLOSER ADJUSTMENT

NOTE:
Closing arcs (“CLOSE” and “LATCH”) are controlled by two(2)separate speed adjusting valves, adjust the CLOSING speed first, then adjust the LATCHING speed.

“CLOSING” speed adjustment is accomplished by full rotations of the speed adjusting valve. Turn the speed-adjusting valve CLOCKWISE for a SLOWER closing speed. Turn the speed-adjusting valve COUNTER-CLOCKWISE for a FASTER closing speed.
“LATCH” speed adjustment is accomplished by full rotation of the speed adjusting valve. Turn the speed adjusting screw CLOCKWISE for a SLOWER latching speed. Turn the speed adjusting screw COUNTER CLOCKWISE for a FASTER latching speed.
CAUTION!!
Do not turn speed adjusting valve more than two(2) full turns counter- clockwise from its factory set position, as two speed adjusting valves could become dislodged from the door closer body resulting in the loss of internal fluid and failure of the device.
