Manual Bypass Valve

A bypass valve has been provided that can override the
hydraulic lock that normally secures the arm from being lifted.
In the event of a power failure, manual operation is achieved
through the following procedure.
1. Find the manual bypass valve with the black round knob,
which is located on the hydraulic pump just above where
the hoses connect. The barrier arm can now be manually
lifted, beginning from the tip, by moving "hand over
hand" while walking towards the operator. When the arm
is open, be certain to close the bypass valve to prevent
the arm from drifting down.
2. Press Open or Close to place the arm at a 45° angle.
3. Press Stop when the arm reaches a 45° angle.
4. Close the Needle valve. Loosen the lock nut and turn the valve CW until it stops.
5. Pull the black Manual Bypass knob out and lock it open by twisting it ¼ turn before releasing it.
6. Slowly turn the Needle valve CCW until the arm lowers slowly and smoothly.
7. Twist the black Manual Bypass knob so it re-seats itself in the closed position.

Cycle Test the Arm

1. Tighten all lock nuts on the adjustor valves.
2. Cycle the arm Open and Close a few times. If adjustments are needed, follow the steps above.
