Door Closer Adjustment :
Closing Cycle :
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 CLOSE arc closing speed.
- Turn the speed adjusting valve COUNTER-CLOCKWISE for a FASTER CLOSE arc closing speed.
“LATCH”speed adjustment is accomplished by full rotations of the speed adjusting valve.
- Turn the speed adjusting screw CLOCKWISE for a SLOWER LATCH arc closing speed.
- Turn the speed adjusting screw COUNTER-CLOCKWISE for a FASTER LATCH arc closing 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.
