Handling and safety precautions
Be sure to read and understand this manual before installation and use of our ILG/D-gearbox.
Storage
The gearboxes need to be stored in a safe way to avoid accidents. Also avoid storage in areas subjected to high
temperature extremes and /or areas subjected to large amounts of humidity and dust.
Handling
Never drop the gearbox or subject it to strong impact.
Correct use
Before installation , be sure the gearbox will NOT be overloaded during normal use. This means the gearbox
must be suited for the valve and actuator to which it is mounted. For checking, see table 1 for the maximum
allowable torque.
