7.3.2 Oil changes
Smaller BS worm gear units are supplied lubricated for life except for the following conditions: Units that are required
to work in explosive atmosphere (94/9/EC ATEX 100a Group II Category 2 Zones 1 & 21 & Category 3 Zones 2 & 22)
should be drained and refilled with correct quantity of lubricant in accordance with the renewal period of Table M2.
See Appendix 4 for correct oil quantity.
Following factors should be used to determine the frequency at which oil changes are carried out:
a. Oil temperature – unit operating under load
b. Type of oil
c. Environment – humidity, dust, etc.
d. Operating conditions – shock, loading, etc.
At elevated temperatures the effective life of the oil is very much reduced. To prevent damage to the unit through lubricant
breakdown the oil should be renewed as detailed in Table M2.
Table M1
Note! Figures quoted are for oil temperatures when the unit has attained normal running temperature when operating
under load. These figures are based on normal running but where conditions are particularly severe it may be necessary
to change the oil more frequently. When changing lubricant, if same lubricant is not used the unit must be flushed out and
filled with one type of lubricant.
