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)
Note: Center threaded hole of slider arm should
align with seventh hole of the slider tube
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 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).

wrench, turn the power adjustment shaft clockwise
increase door closing power. Door control is shipped set at

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: 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.
Latch Valve
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.
Step 11: Make wiring connections using Wiring Instructions on Page 7
and 8.
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.
