To change the hydraulic fluid,
1. Position the gate so the cylinder is fully retracted.
2. Remove the reservoir from the pump pack.
3. Completely empty it.
4. Wipe the reservoir clean and clean the debris screen.
5.
Re-assemble the pump unit and refill it with new Uniflow hydraulic fluid.
6.
To avoid overfilling, slowly pour the fluid through the filler port near the reservoir’s top until the fluid is
within ½ inch of the port’s opening.
7. Replace the plug and wipe up any spilled fluid. Spilled fluid dries to a sticky and messy consistency.
Cold Weather Issues:
1.
Check that your reservoir is filled with our Uniflow high performance fluid.
2. Excessive ice buildup can partially or totally jam gate operation. Operate the gate manually, while
clearing the ice buildup.
3. If the operator is located in an area of extreme snow conditions, regular maintenance to dig the
operator out may be required. A heater option may help.
NOTE:
A biodegradable fluid option does exist, but it does not have the same fluid viscosity at extremely low temperatures.
Uniflow fluid temperature rating is between -40°F and 158°F (-40°C and 70°C). The biodegradable fluid has a temperature rating
between -10°F and 158°F (-23°C and 70°C).
Brake Valve Adjustments
WARNING
The contents of the hydraulic cylinder are under pressure. Close the gate prior to making any brake adjustments
or disassembly to the manifold connected to the hydraulic cylinder. Failure to close the gate may result in
personal injury.
Proper adjustment of the brake valves is important for smooth operation of the gate.
Adjustment of the brake valves, one for each direction of
travel, will determine how quickly the gate actually stops.
Heavy, long gates will need more brake adjustments than
smaller, lighter gates. If adjustment is needed, loosen the
>\zn
-inch lock nut on the top of the brake valve and make
¼-inch incremental turns on the adjustment stem with a
B\cx
hex key.
The adjustment is counter-intuitive.
If the gate passes it’s learned limit point, a counter-
clockwise adjustment stops the gate more rapidly. If the adjustment is set too tight, the system pressure will
increase, the gate speed may decrease, the gate will jerk to a stop, and the IES may trip.
Brake valves are factory-set to midpoint, two turns. This should be sufficient for most applications. When the
adjustment is complete, retighten the
>\zn
-inch lock nut to hold the setting.
