meCHanICal Issues
General problems concerning gate movement can usually be resolved by using the hand pump and manually
moving the gate open and close.
General maintenance recommends scheduled inspection of all fasteners to make sure they are tightened securely
and torqued to proper specications. For torque specs, refer to General Maintenance.
HYdraulIC Issues
The speed at which the operator moves the gate is determined by the size of the hydraulic pump and software
settings.
Attempting to slow gate speed by changing a valve setting will cause inefciency and increased heating of the
hydraulic system, which will degrade system performance and also may result in premature system failure.
NOTE: If the gate speed must be changed, contact your HySecurity distributor or HySecurity Tech Support.
Extremely cold weather is unlikely to seriously affect the gate speed because HySecurity employs a special grade
of hydraulic uid (Uniow), which maintains a linear viscosity over a broad temperature range. This high quality
uid, combined with other design considerations, allows HySecurity to rate its operators for service in ambient
temperatures of -40°F to 158°F (-40°C to 70°C).
If the gate speed of your operator has been affected by cold weather, perform the following:
1. Verify the gate hardware is not impaired by ice.
2. Verify that the reservoir is lled with Uniow uid.
NOTE: Consider adding a heater in extreme cold weather regions. A biodegradable uid option does exist, but
it does not have the same uid viscosity at extremely low temperatures. The biodegradable uid option has a
temperature rating between -10°F and 158°F (-23°C and 70°C).
