LUBRICATION GUIDANCE
Lubrication frequency will vary, depending on turbine operating hours and ambient temperature. It is therefore
suggested that the purchaser keep records of lubrication intervals to determine variances between periods
listed on the chart and those scheduled for a specific installation. Refer to vendor supplied component instruc-
tion included in the System Description sections for maintenance lubrication requirements.
The lubricants listed do not exclude comparable products from other oil companies. Should the purchaser wish
to use an alternate lubricant not mentioned, or recommended by the component manufacturer, approval must
be requested from the component manufacturer, not the GE Company. The use of lubricant grades other than
those recommended, should be first approved by the GE Company.
**WARNING**
Motor shaft must be stationary when relubricating.
CAUTION
Bearing and grease must be kept free of dirt.
GAS TURBINE COMPRESSOR CLEANING
