Regular Arm Closer Adjustment Closing Speed ... Controlled by the
regulating valve on the end of the closer
closest to the hinge.
Sweep Speed ... Controls the door's
speed in the sweep speed range, see
illustration. Full 360° clockwise turns
decrease the sweep speed. Full 360°
counter-clockwise turns increase the
sweep speed.
Latch Speed ... Controls the door's speed
in the latch speed range, see illustration. A
partial turn, up to a maximum of 1/2 turn
(180°) in either direction determines the
latch speed.
Backcheck ... Controlled by the regulating
valve on the end of the closer farthest
from the hinge. Backcheck cushions or
slows the door opening speed near the
end of the opening cycle. Full 360°
clockwise turns increases resistance to
opening. Full 360° counter-clockwise
turns decreases resistance to opening.
Note: If backcheck is encountered
extremely early in the opening cycle,
rotate the valve 1/2 turn (180°) to eliminate
early opening resistance.
Caution ... To avoid damage to closer,
never fully close the backcheck regulating
valve.
