Is it advisable to re-grease a motor while it is running?

Re-greasing a motor while it is running is not advisable because doing so can pose several risks. When a motor operates, it generates heat and vibration, which can lead to the improper distribution of grease. This can cause the grease to fail in providing adequate lubrication. Furthermore, introducing grease into a running motor can lead to excess grease being forced out, potentially causing contamination of the surrounding area and other mechanical components.

In addition to lubricant effectiveness, safety is also a significant concern. The moving parts of a running motor present an immediate risk of injury, and re-greasing under such conditions can lead to accidents. It's important to turn off the motor and ensure it's safe and cool before performing any maintenance related to lubrication. This approach helps maintain the integrity of the lubrication system and ensures the machinery operates efficiently and safely.
