Here is a list of items that should be checked on a routine basis.
Check for loose or broken fasteners -
This check should also include the fasteners on
the gate panel. A broken fastener on the gate panel could cause undue stress on the
operator. Also, inspect the anchor bolts that hold the gate operator in position. While
inspecting these bolts, check for signs the operator has “walked” out of its original
mounting position.
Cycle test the operator -
Run the gate through several cycles to confirm that there is no
binding of the gate panel and that the drive rail is properly aligned with the gate operator.
Also, monitor the wheels for slippage. If the wheels slip, tighten down on the spring
adjustment nut until no slippage occurs during normal gate travel. Tighten the spring only
enough to eliminate slippage during normal travel.
Remove the vent cap and check the hydraulic fluid level
-The vent cap is located on
the reservoir assembly (bottom right of the operator). After removing the vent plug, a
visual inspection should show the fluid level approximately 1” below the vent plug. If
fluid needs to be added, please contact the factory.
IMPORTANT NOTE:
All B&B ARMR operators ship with Envirologic 132 hydraulic
fluid, a biodegradable vegetable based fluid. If another hydraulic fluid is substituted; the
existing fluid must be drained to avoid mixing. Never mix hydraulic fluids!
Check for leaks in the hydraulic system -
This includes the hydraulic lines, reservoir
and fittings. Leakage may occur in the fittings after a period use. If this happens,
moderate tightening of the hose fittings should stop the leakage. If the leak persists,
replace the leaking hose assembly. NOTE: It is recommended that the hydraulic fluid be
replaced at every 1-2 years if installation is high cycle (>300/day), or every 2-4 years if
cycles are < 200/day.
Check for loose or frayed wires -
Carefully inspect all input and output connections to
ensure all wires are seated properly in the terminal blocks. A loose or frayed wire can
create different “phantom” problems.
Check gate input devices for proper operation -
These devices include push buttons,
keypads, loops, etc. An improperly functioning input device could give the impression
the gate operator is malfunctioning.
Test all safety devices for proper operation -
Test the inherent safety to ensure the gate
reverses after coming in contact with an obstruction. Adjust the parameter if needed.
