FLUID LEVEL:
Inspect the oil level semi-annually. Under normal conditions, hydraulic systems do not
consume oil. If there is any evidence of leaking, or if the oil level is being checked for maintenance purposes,
use the following procedure: with a 5/16" Allen wrench, remove the shiny metal plug near the top of the
reservoir. Use a tool, or piece of wire to dip into the reservoir to measure the oil level. Add oil if the level is
more than one inch below the filler port. We recommend our
UNIFLOW hydraulic oil. Part number H 004,
as sold in one gallon units by Hy-Security Gate. Automatic transmission fluid may be used, although its
performance will be sluggish in freezing weather, unless the operator is well heated. Other hydraulic oils,
although technically compatible, tend to be too viscous for proper performance, even in modestly cool
weather.
NEVER USE BRAKE FLUID!
LOOK FOR LEAKS:
If the oil level is ever found to be low, check the system thoroughly for leaks. Because all
of the hydraulic fittings are SAE straight thread, with "O" ring seals, or JIC flare fittings, any leak should be
eliminated by simply tightening the fitting slightly. Rarely, an "O" ring may need to be replaced, if it was
damaged. Pipe dope, or teflon tape is not used at any connection point. If oil was found to be leaking from
the breather cap, verify that the reservoir is not overflowing, or check the relief valve setting according to our
document number G40.
OIL CHANGE:
Unlike gasoline engines, hydraulic systems do not foul oil with combustion products; thus oil
changes do not need to be frequent. Heat is the main concern. If the unit is subjected to high use, especially
those in warm climates, consider changing the oil more frequently. In general, we recommend draining the
reservoir and replacing the oil at five or ten year intervals.
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.
DIRECTIONAL VALVE:
Our operators employ a two position, single solenoid, directional valve. When 24 volt
power is applied, the flow is directed to open the gate. In its normal spring loaded relaxed position the flow is
directed to close the gate. The directional valve is totally maintenance free.
