Which of the following is a key factor in maintaining power tools?

Regular cleaning and lubrication is essential in maintaining power tools for several reasons. First, cleaning removes dust, debris, and any residual materials that could interfere with the tool's functionality. This prevents clogging, overheating, and wear on components that could lead to breakdowns.

Lubrication is equally important, as it reduces friction between moving parts, ensuring smooth operation and prolonging the life of the tool. Properly lubricated tools are less likely to experience mechanical failure, which can occur when components wear prematurely due to inadequate lubrication.

This practice also enhances safety, as a well-maintained tool operates more efficiently and reduces the risk of malfunctions that could lead to accidents. In contrast, using tools only during daytime does not significantly influence their maintenance, and storing them in a cold environment could negatively impact their performance due to potential lubrication thickening. Additionally, while avoiding humid conditions can be beneficial, it does not address the fundamental maintenance tasks that directly affect the longevity and reliability of power tools.
