Special Notes:
*1. Damage to the barrier arm is usually the result of vehicular contact with the arm. Contact with the
arm can also cause the crankshaft bearings to become loose or cracked if the contact force is great
enough. This is not a warranty Issue.
*2. Confirm that the anchor bolts
are tight and that the chassis hadn’t shifted, which can also happen with
vehicle contact to the operator.
*3. Check to see that the limit cams are tight and that they contact the limit switches enough to trip them
but not crushing the limit switches.
*4. The oil level should remain approximately one inch below the filler hole. See maintenance instructions
for oil filling. Loss of fluid is not normal and indicates a leak that must be located and repaired. The cap
for the filler hole is a breather and ne
eds only to be finger tight. Use ―Uniflow‖ fluid, part # MX000970, if
additional fluid is required.
*5. To drain the hydraulic oil, leave the arm in the closed position, and disconnect the hydraulic hose
where it connects to the top of the hydraulic cylinder. Place the disconnected hose into a waste
receptacle and start the gate in the open direction. All of the oil will drain within 15 seconds. Stop the
pump immediately, when the flow ceases. Re-connect the loose hose. Refill with new UNIFLOW
hydraulic oil available from the factory, or use a substitute, if performance in cold weather is not a
question.
*6. Confirm that the brake valves are stopping the arm properly, and adjust if needed.
*7. Replace battery with DL 2025 / DL 2032 or CR 2025 / CR2032.
*8 DC Operators use DC motors with carbon brushes which wear in normal operation. Worn brushes
can damage the DC motor. Under severe conditions HySecurity recommends that brushes be checked
after 2 years and the replacement interval be adjusted as necessary.
