8.2 OIL CHANGES
1. Place an adequate container under the drain plug.
2. Remove the ller and drain plugs and allow the oil to drain out.
The oil will drain better if it is warm.
3. Wait for a few minutes until all the oil has drained out, then screw the drain plug back on after
rst changing the plug seal.
4. Fill with new oil until it reaches the level mark. Do not mix oils of different makes or speci-
cations and check that the oil is highly resistant to foaming and is EP rated.
5. Tighten down the ller plug after changing its seal.
The gear unit may be supplied with or without lubricant, as requested by the User. The
quantity of charge oil required is specied in the Sales Catalogue. This specication is
however, approximate, and reference must always be made to the mark on the level plug,
the placement of which depends on the mounting position specied in the purchase order.
Life lubricated gear units which are not subject to external contamination do not normally
require periodic lubricant changes. If the same type of oil as that already in use is not avail-
able, drain the gear unit casing completely and wash its interior thoroughly with a light solvent
before relling with the new lubricant.
If a leak is found, identify the cause of the fault and repair it before topping up the lubricant
and operating the unit.
Lubricants, solvents and detergents are toxic/harmful to health:
- they may cause irritation in direct contact with the skin
- they may cause intoxication if inhaled
- they may be fatal if swallowed.
