6 Lubrication
Proper lubrication is responsible for the performance and service life of the gearbox/geared motor. The
gearboxes are lubricated by oil bath and equipped with a level indicator plug, which can be a level gauge or
a hexagonal plug model HN10-WD (similar to DIN 510), differing from the other plugs in the gearbox/geared
motor.
The correct oil level is in the center of the sight glass (when of the "level glass" type) or in the plug level (when
of the hexagonal plug type) with the gearbox stationary and in the required working position.
Before starting operation, check that the gearbox is filled with oil and that the lubricant level is adequate as
recommended.
The operating temperature is the temperature of the lubricating oil after the temperature stabilization period
at full load (period after approx. 3 hours of continuous operation).
The minimum ambient temperature for the start of operation of gearboxes and geared motors depends on the
viscosity and type of lubricating oil.
The table below shows the minimum ambient temperature for the start-up of gearboxes and geared motors:

Contact WEG-CESTARI for other temperatures.
The external temperature of the housing is approximately 15°C lower than the operating temperature (oil
temperature).
When changing gears, the oil must be drained while still "warm" because the viscosity of the oil is lower,
facilitating the draining and cleaning.
NOTE:
The lubricant used must be disposed of in accordance with current legislation and the guidelines
contained in the Environmental Guidelines chapter of this manual.
When changing gears, use the same oil as indicated on the gearbox nameplate and specified in this manual.
It is not recommended to mix oils of different types and manufacturers.
The oil must be changed every 3500 hours or annually.
