Lubricants; Oil Change - Siemens SIMOTICS GP Compact Operating Instructions

8.2 - LUBRICANTS

Before putting the gear unit into service, check the oil level. This must be done with the gear unit in the mo-
unting position in which it will be used in the application. If necessary, if or top up the lubricant to the filling
mark on the level cap which may be transparent or of the spill type.
Life-time lubricated gear units which are not subject to external contamination do not nor-
mally require periodic lubricant changes.
Do not mix oils of different nature or specifications and check that the oil is highly resistant to
foaming and is EP rated.
If the same type of oil as that already in use is not available, drain the gear unit completely and flush its inte-
rior thoroughly with a light solvent before refilling with a new lubricant.

8.3 - OIL CHANGE

1. Place an adequate container under the drain plug.
2. Remove the filler 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 with a new ga-
sket.
4. Fill the gear unit with the new oil (in its actual mounting position) to the centre of the level plug.
5. Tighten down the filler plug after fitting a new gasket.
The gear unit may be supplied with or without lubricant, as specified by the User. The quan-
tity of oil to be filled is specified in the Sales Catalogue. This specification is, however, appro-
ximate, and reference must always be made to the centre of the level plug, the placement of
which depends on the mounting position specified in the order.
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 can be fatal if swallowed.
Handle them with care using suitable individual safety equipment. Do not dump into the environment
and dispose of in compliance with applicable legislation.
If a leak is found, identify the cause of the fault, repair it and refill with lubricant before opera-
ting the gear unit.
