Which of the following is NOT part of the pre-cleaning steps for TruDefender?

• A. Power off unit
• B. Seal access door
• C. Disassemble crusher
• D. Power on the unit

Answer: (D)

The essential idea here is safety and proper access before cleaning. Before you start cleaning, you must make sure the equipment is fully de-energized and isolated so there’s no risk of it starting up or releasing energy during the cleaning process. Turning the unit off removes the danger of accidental operation that could injure you or damage components.

Sealing the access door is about containment and security. It prevents dust, debris, and any contaminants from escaping to the surrounding area while you’re cleaning, and it also helps ensure you don’t get exposed when you’re working inside.

Disassembling the crusher, if required, gives you access to surfaces or internal parts that aren’t reachable in place. This step may be necessary to thoroughly clean all affected areas and remove buildup.

Powering the unit back on is done after cleaning and reassembly, once you’ve confirmed everything is dry, clean, and correctly reassembled. It’s not part of the pre-cleaning steps because bringing the device back to life should occur only after safety checks and cleaning are complete.
