Which statement about caring for a portable grinder is correct?

  1. Always store it in a damp location

  2. Always carry it by the power cord

  3. Ensure it is unplugged when not in use

  4. Use it with wet hands for better grip

The correct answer is: Ensure it is unplugged when not in use

Ensuring that a portable grinder is unplugged when not in use is an essential safety practice. This precaution prevents accidental starts, which could potentially lead to injuries. By disconnecting the power source, you eliminate the risk of the grinder being activated inadvertently while it is being stored or moved. This practice is particularly important in work environments where multiple operators may use the same tool, as it enhances safety for everyone involved. The other options suggest methods that could compromise safety. Storing a grinder in a damp location could lead to rust and damage to the electrical components, impacting both performance and safety. Carrying a grinder by the power cord poses a risk of damaging the cord, which could lead to electrical hazards. Using a grinder with wet hands increases the chance of electrical shock, making it a dangerous practice.
