• Prepare the gear unit for lifting by attaching straps, hooks and screw clamps etc. to its attach-
ment points. Alternatively, use a pallet to move the load. If using a crane, rst lift the gear unit
vertically out of its packaging.
• If using a lift truck or pallet truck, remove the packaging and insert the truck’s forks at the indicat-
ed positions.
• First lift the load very slowly to check that it is stable.
• Move the gear unit to the unloading area and lower it gently into position, taking care not to tip it
suddenly in transit.
If the gear unit is already equipped with an electric motor, do not use the eyebolts on the
motor casing for lifting, unless expressly specied.
4.3 STORAGE
The following recommendations should be followed when storing the gear unit.
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 subject 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 to be stored for more than 6 months, the following additional precautions must
be taken:
5. Cover all machined external surfaces with a rustproong product such as Shell Ensis or other
product with similar properties and application range.
6. Fill the unit with lubricating oil and make sure the vent plug is positioned uppermost. Before
putting the unit into service, the oil used for storage must be drained and replaced with the correct
quantity of recommended operating lubricant.
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 rustproong product,
contaminants and other impurities (use a standard commercial solvent).
Do this outside the explosion hazard area.
The solvent must not touch the seal rings as this may damage them, causing them to leak
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 lling
with the operating oil.
The service life of the bearing grease is reduced if the unit is stored for more than 1 year.
The bearing grease must be synthetic.
