Storage - Siemens SIMOTICS GP Compact Operating Instructions

4.3 - STORAGE

Some recommendations for storing the gear unit are indicated below.
1. Do not store the unit in excessively humid conditions or where it is exposed to the weather (do not store
outdoors).
2. Do not place the gear unit directly on the ground.
3. Place the gear unit on a stable base and make sure that it is not subjected to accidental displacement.
4. Store the packaged gear unit (if allowed) in accordance with the instructions on the packaging itself.
If the gear unit is stored for more than 6 months, the following additional precautions must be taken:
5. Cover all machined external surfaces with a rustproofing product such as Shell Ensis or equivalent pro-
duct with similar properties and application range.
6. Fill the unit with lubricating oil.
SAFETY PRECAUTIONS to be taken when returning the gear unit to service after storage.
The output shafts and external surfaces must be thoroughly cleaned of all rustproofing product,
contaminants and other impurities (use a standard commercial solvent).
Do this outside any explosion hazard area.
The solvent must not touch the seal rings as this can damage them and render them ineffective.
If the oil or protective material used during storage is not compatible with the synthetic oil used
during the machine's operation, the interior of the unit must be thoroughly cleaned before filling
with the operating oil.
The service life of bearing grease is reduced if the unit is stored for more than 1 year.
The bearing grease must be synthetic.
