Which of the following is a daily maintenance task for a chainsaw?

Daily maintenance of a chainsaw is essential to ensure its efficiency and safety during operation. One critical aspect of this maintenance is cleaning the air filter. The air filter plays a vital role in preventing dirt and debris from entering the engine, which can significantly impact performance and lead to engine damage. A clean air filter allows for optimal air intake and helps maintain the correct fuel-to-air ratio, ensuring the chainsaw operates smoothly.

In addition to cleaning the air filter, other tasks such as inspecting bars and chains for wear, checking the fuel filter, and replacing spark plugs can also be important maintenance tasks, but they are generally not performed daily. Regular cleaning of the air filter, however, should be a routine part of daily maintenance to keep the chainsaw functioning effectively.
