Which of the following is NOT a potential problem from using a worn chainsaw chain?

In the context of chainsaw maintenance, a worn chainsaw chain can lead to several issues that adversely affect its performance. The correct option indicates increased lubrication efficiency as a scenario that is not a potential problem associated with using a worn chainsaw chain.

When a chainsaw chain becomes worn, it is typically less effective at cutting efficiently. This can result in erratic cutting patterns, making it difficult to control the tool and achieve smooth cuts. Additionally, a worn chain can lead to overheating of the guide bar, as it creates more friction against the wood due to a poor cutting angle and a lack of sharpness. This excess friction can lead to premature wear on other components as well.

While it might be assumed that a properly lubricated chain should work well, a worn chain often disrupts the lubrication process. Worn teeth can affect how effectively the oil circulates, meaning that lubrication efficiency does not improve but rather decreases under these conditions. Thus, the implication is that using a worn chain can negatively impact lubrication, highlighting that increased lubrication efficiency is not a problem linked to wearing.

In summary, using a worn chainsaw chain does not enhance lubrication efficiency; rather, it often worsens performance and increases the potential for breakdowns.
