The Geareducer vent or vent line must be checked for blockage
to prevent failure of pinion shaft oil seal—clean when necessary.
Long-Term Storage or Downtime
indefinite duration
If unit has been in an operational state, perform a
Run Cycle
and drain the oil including volume in the oil line, if equipped. If in
storage, unit does not need to be operated.
Fabricate and install an overflow reservoir system and fill unit
entirely full of oil.
Maintenance Cycle
If unit is stored outdoors, drain condensate
monthly and top off oil as necessary. If unit is stored indoors,
but not climate controlled, maintenance cycle may be extended
to 3 months. If stored in climate controlled space, cycle may be
extended to once per year.
