Drive motors with
permanent lubrication
As a rule, the bearings of the drive motors are provided with a maintenance
free permanent lubrication.
Under normal operating conditions (refrigerant temperature max. 104°F, con-
tinous operation) the bearings are maintenance free for the service life.
The service life decreases or increases as thermal stress increases or de-
creases (due to increased or reduced refrigerant temperature).
Changing the V-belt
Check:
– 1x per year for damages.
Change:
– In case of visible damages.
WARNING!
Have BOGE service dismantle the bearings and install new bearings once
the specified service life has expired.
NOTICE!
The BOGE GM drive system automatically adjusts the belt drive in every
operating status to the correct tensioning.
Thus maintenance of the belt drive is reduced to the tasks mentioned above.
