Check closing time, and adjust closer if needed.
Opening the regulation valves (described below) too
far may result in the closer leaking oil! This may result
in closer and property damage, and personal injury.
FOLLOW ALL INSTRUCTIONS CAREFULLY.
L Valve must be closed CW to seat, never more than 3 turns
CCW from seated position. Adjust the valves in 1/4 turn
increments or less at a time. DO NOT TURN MORE THAN
3 FULL ROTATIONS. THIS WILL CAUSE THE CLOSER TO
LEAK OIL!
L DO NOT ADJUST THE LATCH SPEED IF THE DOOR DOES
NOT LATCH. If this occurs, adjust the spring force.
1. Open the door to 90°, measure how long the door takes to
close and latch. A typical closing time is 5 to 7 seconds, evenly
divided between main speed and latch speed.
2. If the closing time needs to be adjusted, use the closer valves
described below.
a. Backcheck (BC)- this controls door speed opening as the
door angle approaches 90°. Do not use as a door stop.
b. Main Speed (M)- this controls door speed during most of
the closing motion.
Screw Type
Wood (for wood doors & frames)
Machine (for metal doors & frames)
Requires hole drilling & tapping; best hold.
SRT - Self Reaming & Tapping (for metal doors
& frames)
Screw Type
Fifth Hole Spacer
Thru Bolts
Pinion Attachment Screw
Cover Screws
Closer Valve Adjustment
CAUTION
Optional Hold Open Arms
To adjust Optional Hold-open arm:
To engage or disengage hold open
feature, turn control handle 1/4 turn.
c. Latch Speed (L)- this controls door speed during the last
few degrees of door closing.
d. DA Speed (D)- this controls the delay speed for DA cylinders.
This valve is present on DA cylinders only.
3. Turn the valves clockwise to decrease door speed, and
counterclockwise to increase door speed. The latch speed and
main speed should be adjusted together.
