— General Maintenance
Hydraulic System
Fluid Level: Under normal conditions, hydraulic systems do not consume oil. Before adding any oil, check the system
thoroughly for leaks. Remove the bright metal plug in the tank, fill to plug level, then replace plug. We only recommend
our Uniflow hydraulic oil; part number MX000970, which is sold in one-gallon containers by our distributors. Never use
brake fluid. It will severely damage the hydraulic system. Use of any oil other than Uniflow oil 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.
Oil Change: A hydraulic system does not foul its oil, unlike a gas engine. Oil changes do not need to be frequent.
HySecurity recommends draining the reservoir and replacing the oil at five-year intervals. Oil breakdown caused by heat
is the main concern. If the unit is subjected to high use, especially in a warm climate, change the oil more frequently.
To change the hydraulic oil, remove the reservoir from the pump unit, completely empty it, wipe the reservoir clean, and
clean the derby screen before re-assembling. Refill with new Uniflow hydraulic oil (available from your distributor). To
avoid overfilling, fill only through the removable plug opening near the tank top. Slowly pour the oil into the tank until the
oil is within one inch of the filler port. Replace the plug and wipe up any spilled oil. Spilled oil will dry to a very sticky and
messy consistency.
Cold Weather:
1. Check that your reservoir is filled with our Uniflow high performance oil.
2. Excessive ice buildup can partly or totally jam gate operation. Check function by operating the gate manually.
3. If the operator is located in an area of extreme snow conditions, regular maintenance to dig the operator out and clear
the rail is required. A heater option may help, but the SlideDriver will not operate well if it is covered with 5ft of snow.
Electrical Controls
Before servicing, turn off power and disconnect switch.
No routine maintenance is needed for the electrical system or controls.
If the environment is very sandy or dusty, or has many insects, be
certain to seal all electrical enclosure holes. Blow the dust out of the
electric panel with compressed air. A qualified technician may
troubleshoot with the aid of the troubleshooting guide in this appendix.
If it is necessary to call a distributor for assistance, be sure to have
your model and serial number ready. Other helpful information would
include the name of the job, approximate date of installation, and
operator service record, especially any work that has been done
recently.
How to Adjust the Pressure Relief Valve: To check your relief valve
setting, first disconnect the hoses. Run the operator either open or
closed (the gate will not move with the hose disconnected). The
pressure gauge will show current relief pressure. The relief valve is
found on the pump pack. It has an adjusting head and lock nut. To adjust, loosen the lock nut and screw the threaded bolt
clockwise for increased pressure, counterclockwise to decrease pressure. More information is available
on the yellow
tag attached to the pump pack.
NOTE: There is limited value in using the relief valve as an entrapment protection device. Photo eyes or gate edges are the best
methods to protect pedestrians and maintain reserve power to reliably drive the gate.
