Which statements regarding maintenance of power tools and equipment are true?

• A. All three statements are true.
• B. Statement 1 and 2 are true; statement 3 is false.
• C. Statement 1 is true; statements 2 and 3 are false.
• D. Statement 1 is false; statements 2 and 3 are true.

Answer: (D)

Maintaining power tools and equipment is about routine care that keeps them safe to use and reliable. Before using a tool, do a quick check for damage, wear, and proper function of safety features like guards and switches, and make sure cords, batteries, and plugs are intact. If anything looks off, don't use the tool until it’s been repaired or inspected. After finishing, clean off dust and debris, keep moving parts lubricated as the manufacturer recommends, recharge or replace batteries as needed, and store the tool in a dry, secure place. These steps protect you from injuries and help the tool last longer.

The belief that only a supervisor should perform maintenance isn’t accurate. Routine maintenance and pre-use checks can and should be done by trained users following the manufacturer’s instructions; more complex repairs or calibrations should be left to qualified personnel. That’s why the first statement is false while the second and third are true.
