Adjust the threaded end of the index arm to place the free end of the gate in an exact position for the
locking pin to strike and slide down into the receptacle as the gate closes. The most reliable index
arm adjustment will allow the gate to swing slightly past center so that the lock pin strikes the back of
the receptacle. Tighten all parts of the index arm assembly firmly for trouble free operation.

Adjustment of the Flow Control Regulating Valve
HRG Swing gate operators employ the use of a flow control
valve to control the closing speed of the gate. The flow
control valve is the small rectangular brass device with the
knurled adjusting knob, located just above the red quick-
disconnect fitting for the hydraulic hose.
To adjust the close flow control valve correctly, pre-set the
valve set such that only two of the color bands (red & blue)
below the adjusting knob are exposed. Run the gate in the
close direction and turn the flow control valve clockwise until
you have achieved a good control of the gate in the closed
direction. The most crucial part of the closing of the swing
gate is when the lock pin strikes its receptacle. The flow control valve adjustment is most helpful for
maintaining control at this point of operation. (Other important adjustments are necessary for correct
locking. See separate instructions on "Adjustment of Indexing Arm")
Caution: Over-tightening of the flow control valve will cause the operator to draw more motor
horsepower than necessary or desirable, and cause additional stress on the hydraulic power unit.
Be sure to tighten the set screw on the adjusting knob to lock your adjustment.
NOTICE:
If the locking pin mechanism is not used, security of
this system is adversely affected and the operator drive shaft
may be exposed to high stresses by wind loading or vandals. If
the lock pin receptacle is not built or installed to create a strike
stop for the gate, the lock pin may not always align with the
receptacle.
