Mechanical Issues
Gates that run smoothly and operate well signicantly improve the life of the gate operator’s motor and
component parts. Refer to Mechanical Maintenance on page 123.
On site gate movement issues can usually be resolved in the short term by manually moving the gate open
and close. See Emergency Release on page 17.
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).
