1. Do not store the motor in high temperature and extremely humid environmental conditions.
Do not place it in an environment where corrosive gases may be present, as this may cause malfunction.
Recommended environmental conditions: temperature +10°C to +30°C, relative humidity 30% to 95%.
Be especially careful with motors that have been stored for six months or more (three months or more for motors with grease), as their starting performance may deteriorate.

2. Fumigants and their gases may contaminate the metal parts of the motor. If the motor and/or packaging materials such as pallets for the product containing the motor are to be fumigated, the motor must not be exposed to the fumigant and its gases.

3. If silicone materials containing low-molecular silicone compounds adhere to the commutator, brushes or other parts of the motor, the silicone will decompose into SiO2, SiC and other components after the electric energy is rectified, resulting in Contact resistance increases rapidly between commutator and brushes.
Therefore, extreme caution should be exercised when using silicone materials in devices, and also to check that such adhesives or sealing materials do not produce harmful gases, whether used for motor installation or during product assembly. One must pay attention to the best options. Examples of gases: gases produced by cyano adhesives and halogen gases.

4. The environment and operating temperature will more or less affect the performance and life of the motor. When the weather is hot and humid, pay special attention to your surroundings.
