•
No corrosive or aggressive substances must be present in the surrounding area
(contaminated air, ozone, gases, solvents, acids, alkaline solutions, salts, radioactivity,
etc...).
•
Do not subject to vibration or shock.
Measures to be taken during the storage or fallowing period
•
If the relative humidity of the air is less than 50 %, the gearbox may be stored for up to 3
years.
Measures to be taken before commissioning
•
Subject the gearbox to inspection before putting it into operation.
•
If the storage or fallowing period extends beyond approximately 2 years or the
temperature during short-term storage varies significantly from the reference range, it is
necessary to replace the lubricant inside the gearbox before putting into operation.
•
If the gearbox is fully oil-filled, the oil level must be reduced according to the mounting
position before commissioning.
•
If the gearbox is not full of oil, the oil level must be refilled according to the mounting
position before commissioning. For the quantity and type of lubricant please refer to the
information on the gearbox plate.

Pre-installation operations
Check the gearbox immediately upon delivery to verify that it has not suffered damage to
transport and packaging. The operation must be checked and can only be mounted if no leakage
is detected. In particular, check that the shaft rings and caps are not damaged. Immediately
report the damage to the transport company. In case of transport damage, it may not be
possible to start the gearbox.
Before transport, drivers are protected against corrosion by application to bare surfaces and
oil/grease shafts or corrosion products.
Before mounting, completely remove the oil / grease or anti-corrosion products and any dirt
incrustations from all shafts and flanged surfaces.
In cases where an incorrect direction of rotation may cause damage or danger, an no-load test
operation of the group shall be performed to determine the correct direction of rotation of the
output shaft, which shall then be maintained during operation.
For the connection of the motor and during the control of the motor, it is necessary to ensure
that the gearbox can only turn in that direction of rotation, eg. checking the rotation field.
Ensure that no substances are present in the area surrounding the installation site, or are
present during subsequent operation, which may exert an aggressive and corrosive action
against metals, lubricants and elastomers.
If the gearbox has a vent, the vent or pressure vent must be activated before starting. For
activation, remove the transport safety (drawstring).
