• Prepare the gear unit for lifting by attaching straps, hooks and screw clamps etc. to its attachment points.
Alternatively, use a pallet to move the load. lf using a crane, first lift the gear unit vertically out of its packa-
ging.
• lf using a lift truck or pallet truck, remove the packaging and insert the truck's forks at the indicated posi-
tions.
• 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.
/.\ tf the gear unit is already equipped with an electric motor, do not use the eyebolts on the mo-
~
tor casing for lifting, unless expressly specified.
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.
lf 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 rustproofing produet such as Shell Ensis or other produet
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 re-
commended operating lubricant.
14
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 produet,
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
lf 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 the bearing grease is reduced if the unit is stored for more than 1 year.
The bearing grease must be synthetic.
