Fluid Level: Under normal conditions, hydraulic systems do not consume fluid. Check the system thoroughly
for leaks, before adding any fluid. If fluid needs to be added:
1. Remove the metal plug from the tank.
2. Use HySecurity Uniflow hydraulic fluid; part number
MX000970. Gallon sold by our distributors.
3. Use a funnel to fill to within ½ inch of the plug level. Then,
replace plug.
NOTICE: Never use brake fluid. It will severely damage the hydraulic
system. Use of any fluid other than fluid recommended by HySecurity
may void the operator warranty.
Look for leaks: Occasionally there may be slight seeping at the
fittings after some usage. Tightening of the fittings usually corrects
the problem. If leaking persists, replace "O" rings, fittings or
hoses, if required. No further leaks should occur.
To Change Fluid: Unlike a gas engine, the fluid inside a hydraulic
system does not foul, so fluid changes do not need to occur often.
HySecurity recommends draining the reservoir and replacing the
fluid at five-year intervals. Fluid breakdown caused by heat is the
main concern. If the unit is subjected to high use, or you are using
the HySecurity biodegradable fluid option (especially in a warm
climate), change the fluid more frequently.
To change the hydraulic fluid,
1. Remove the reservoir from the pump pack.
2. Completely empty it.
3. Wipe the reservoir clean and clean the debris screen.
4. Re-assemble the pump unit and refill it with new Uniflow hydraulic fluid.
5. 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.
6. 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).
