Warehouse storage Installation
When moving the unit, care should be taken to protect external parts from breakage or damage
due to accidental knocks or falls.
If the unit is to be stored in a hostile atmosphere or for a long period of time (2/4 months), it is
important to apply protective and waterproofing products to avoid deterioration of shafts and
rubber parts.
Before starting up the unit, carry out the following checks:
Check the data shown on the name plate of the reduction unit and/or the electric motor;
Check for any leaks of lubricant
If possible, remove any traces of dirt from the shaft and from the areas around the oil seal.
If the oil seal is not immersed in the lubricant inside the assembly during particularly long
storage periods (4/6 months) it is recommended that it should be replaced as the rubber
might stick to the shaft or even have lost the elasticity it needs to work.
Particular care must be taken when installing drives, as this often the source of damage and
of down time. Careful choice of the type of drive and mounting position can often avoid the
need for protection of sensitive areas, particularly underneath the unit from oil leaks, however
limited they may be.
- The machine must be firmly fastened in place in order to prevent any vibrations.
- Whenever possible, protect the reduction unit from direct sunlight and bad weather, especially
when it is mounted on its vertical axis.
- Make sure the air intake on the fan side is unobstructed in order to ensure that the motor is
correctly cooled.
- In the case of temperatures of < -5 °C or > +40 °C, contact Technical Assistance.
- If the motor is to be started up very often under load, the use of a heat probe inserted into the
motor is recommended.
- The various machine members (pulleys, gear wheels, couplings, etc.) must be mounted on
the shafts using special threaded holes or other systems that ensure correct operation
without risk of causing damage to the bearings or the external parts of the assemblies (fig.1).
- Lubricate the surfaces that come into contact in order to prevent oxidation or seizure.

Installation
Correct and incorrect examples of coupling connections
The pulley must be mounted on the main shaft as close as possible to the shoulder so that is
does not cause excessive radial load on the bearings (fig. 2).Great care must be taken when
connecting the couplings to ensure that they are well aligned, so as not to cause excessive
radial load on the bearings (fig.3).When it is applied, paint must never be used on rubber
parts: oil seal, etc. It must never be applied to any breather holes in plugs if they are mounted
on the unit.In the case of assemblies with oil plugs, remove the closed cap used for transport
and fit it with the breather plug that is supplied with the reduction unit.When the assembly is
supplied without a motor, the following precautions must be followed in order to ensure that
connections are properly made
Mounting the motor on the pam B5/B14 flange
Check that the tolerance of the motor shaft and the motor flange comply with at least one
‘normal’ class of quality. Carefully clean off any trace of dirt or paint from the shaft, the spigot
and the face of the flange. Carry out mounting operations making sure not to use force. If this
is not possible, check the tolerance of the motor key and ensure that it is correctly fitted. Apply
assembly grease to the shaft in order to prevent oxidation or seizure caused by contact.
Good quality motors should be used in order to ensure that the unit works correctly, without
vibrations or noise.
Before mounting the unit on the machine, check that the principal shaft of the reduction unit
rotates in the right direction.
Use the oil window, if present, to check that the lubricant reaches the correct level required for
the mounting position used.
Starting up
The unit should be started up gradually: do not immediately apply the maximum load the
machine is able to take ; look for and correct any malfunction that may be caused by incorrect
mounting.
Running-in is not essential for the reduction unit to run properly since modern construction
techniques for the gears and castings, the extreme cleanliness of the internal parts, and the
excellent qualities of the lubricants used, ensure that the internal parts receive a high degree
of protection even during the first moments.
Servicing
The high degree of finish of the internal parts ensures that the unit will work correctly with only
a minimum amount of servicing
Generally speaking, the following rules should be followed: periodically check that the exterior
of the assembly is clean, especially in the cooling areas; periodically check to see if there are
any leaks, especially in the areas around the oil seals.
Assemblies that are lubricated for life and thus do not have any oil plugs do not require any
special maintenance except as stated above.
For other assemblies, low maintenance is required with an oil change at 8/10,000 hours of
use. The change of oil naturally depends on the type of environment and use to which the unit
is put.
Apart from the normal maintenance rules given above, make sure the breather hole in the plug
is clean and, using the oil window, periodically check that there is sufficient lubricant.
Should it be necessary to top up with lubricant, use the same type that is already in the reducer
or one that is compatible with it.
In case of doubtful incompatibility between lubricants, we recommend you empty out the oil
from the gearbox completely and, before refilling with new oil, wash out the unit to remove any
residue.
When changing the oil, follow the previous instructions.
Troubleshooting
If any problems should arise when starting up the unit or during its first few hours of operation,
contact the after sales service unit of Motovario.
The table shows a series of problems with a description of possible remedies.
It should be borne in mind however that the information given is for reference only as all the
drives manufactured by Motovario are thoroughly tested and checked before they leave the
factory.
Please note that tampering with the assembly without prior authorization from Motovario
immediately invalidates the warranty and often makes it impossible to ascertain the causes of
a defect or malfunction.

The performance given in the catalogue correspond to mounting position B3 or similar, ie.
when the first stage is not entirely immersed in oil. For other mounting positions and/or
particular input speeds, refer to the above tables that highlight different critical situations for
each size of reduction unit.
It is also necessary to take due consideration of and carefully assess the following applications
by calling our Technical Service.
- As a speed increasing.
- Use in services that could be hazardous for people if the reduction unit fails.
- Applications with especially high inertia.
- Use as a lifting winch.
- Applications with high dynamic strain on the case of the reduction unit.
- In places with T° under -5°C or over 40°C.
- Use in chemically aggressive environments.
- Use in a salty environment.
- Mounting positions not envisaged in the catalogue.
- Use in radioactive environments.
- Use in environments pressures other than atmospheric pressure.
- Avoid applications where even partial immersion of the reduction unit is required.
