In a wick lubricator, how often should the wick be rinsed in kerosene?

Never
Only when it is replaced
From time to time
Daily

The correct answer is: From time to time

Wick lubricators are designed to ensure that machinery is adequately lubricated by allowing oil to be drawn up through a wick from a reservoir. Over time, the wick can become contaminated with dust, dirt, or excess lubricant, which can hinder its ability to deliver the necessary lubrication. Rinsing the wick in kerosene helps to clean it and restore its ability to draw oil effectively. This maintenance task should not be done excessively, as rinsing too often can lead to premature wick deterioration. However, performing this rinsing from time to time is advisable, as it keeps the wick in good operating condition and ensures that the machinery remains properly lubricated. Therefore, rinsing the wick in kerosene on a periodic basis, as indicated in the chosen response, strikes a balance between maintenance and preservation of the wick’s functionality. This routine upkeep is essential for the optimal performance of the wick lubricator system.
