Step 5: Mount track assembly to door using 3 1/4-20 screws & sex nuts
with buffer assembly toward hinge. Open part of track to face
top of door.
Step 6: Insert slide arm rod into slide arm tube setting the distance
between the pinion square and the slide stud at 13-1/2” (343).
Install 9/64” hex drive socket head screw from screw pack.
(See illustration below)
Step 7: Using an adjustable wrench, rotate pinion 45° toward hinge,
as shown below. With the arm assembly parallel to the
door, secure arm to pinion when square of the pinion aligns
with the square in the arm. Secure with countersunk
washer and 1/4-20 Flat Head Screw (with thread lock)
provided. Tighten screw with 7/16” wrench or socket.
Step 9:
to
increase door closing power. Door control is shipped set at
midpoint of power setting. Maximum closing power can be
achieved with 8 (360°) clockwise turns of the power
adjustment screw.
Step 8: Insert arm stud into slide block in track assembly. Secure by
pushing in on the retainer clip that extends from the slide
block in the track, until it is flush with the slide block (see
illustration below).
Adjust closing power of unit (See Fig. 1) - Using a 1/8” allen
wrench, turn the power adjustment shaft clockwise
Step 10: Adjust Hydraulic valves using a 1/8” hex wrench to obtain
proper door closing speeds. See following illustrations. Refer
to Table 1 below for recommended minimum opening /
closing times per ANSI/BHMA A156.19.
Note: A.D.A. requires that from an open position of 70°, the
door will take at least 3 seconds to move to a point 3” (75mm)
from the latched position, measured at the leading edge of
the door.
Closing Cycle – Make adjustments, as necessary, to the Sweep
Speed "S" valve and Latch Speed "L" valve. See Fig. 2 below for
location of valves. Turn valves clockwise to reduce speed, counter
clockwise to increase speed.
Opening Cycle – Adjust Backcheck, "B" valve, as necessary, for
hydraulic resistance to door opening in the backcheck range. See
illustration in Fig. 2 for location of valve.
NOTE: Too much Backcheck, "B" valve, can affect the
operation of the units pump, preventing units from fully
opening the door. This valve may require fine tuning after all
other adjustments have been made.

Backcheck - adjust the backcheck valve to have a minimum
opening time to backcheck or 80 degrees (whichever comes
first) based on Table 1.
Closing Time - adjust Latch and Sweep valves to have a
minimum closing time from 90 degrees to Latch Check or
10 degrees (whichever comes first) based on Table 1.
