Maintenance of the G.G system consist entirely of insuring
that clean dry air reaches the control unit. The air tank has
a drain cock to drain the condensate water in the tank. In
addition the filter/lubricator/regulator unit has an
automatic water separator followed by a lubricator which
injects a fine mist of oil in the stream of air to insure
adequate lubrication of all components of the system. Thus,
the system requires minimum maintenance, nevertheless the
following ere some steps to insure perfect performance :
1- Check the oil level in the lubricator unit and top as
required with light weight mineral oil ( approximately
every 400 hours of stabilizer operation ).
2- Adjust springs tension in control unit to equalize the
pressure readings on the top two gauges ( the pressure going
through amplifiers ) when the gyro is in the central
position. Adjustment should be carried out only lf the
pressure differential exceeds 10 psi.
3- Check of free movement of fins by rotating the hex shaft
back and forth.
4- The control unit is the brain of the system. If the unit
appears to be malfunctioning, please remove from bulkhead and
send back to the fecEory for tuning at no cost to you. Do
not attempt to repair or adjust the control unit beyond step
# 2 above.
