Which of the following issues can arise from using worn chains and guidebars?

Using worn chains and guidebars can lead to a significant issue where the chainsaw does not cut in a straight line. Worn components negatively affect the alignment and performance of the cutting system. When the chain is dull or the guidebar is worn unevenly, it can cause the chain to deviate from a straight path during operation. This misalignment can make it difficult to achieve accurate and clean cuts, which is essential for effective chainsaw use.

In contrast, a properly maintained chainsaw with sharp chains and uniform guidebars will provide stable and straight cuts, enhancing both efficiency and safety during operation. This emphasizes the importance of regular maintenance and inspection of chainsaw components to ensure optimal cutting performance.
