  Technical Data
page 1 of 1
To install the reduction unit it is necessary to note the following recommendations:
1. The mounting on the machine must be stable to avoid any vibration.
2. Check the correct direction of rotation of the reduction unit output shaft before fitting      the unit to the machine.
3. In the case of particularly lengthy periods of storage (4/6 months), if the oil seal is      not  immersed in the lubricant inside the unit, it is recommended to change it since      the rubber could stick to the shaft or may even have lost the elasticity it needs to      function properly.
4. Whenever possible, protect the reduction unit against solar radiation and bad weather.
5. Ensure the motor cools correctly by assuring good passage of air from the fan side.
6. In the case of ambient temperatures < -5°C or > +40°C call the Technical Service.
7. Painting must definitely not go over rubber parts, if any.
8. Starting must take place gradually, without immediately applying the maximum load.
