What items can you use for repair and adjustment of electrical items?

When it comes to the repair and adjustment of electrical items, adhering to safety and operational standards is crucial. The correct choice emphasizes that only items authorized for use by technical data or manufacturer's guidelines should be utilized. These guidelines ensure that the tools and materials are specifically designed for the task at hand, which minimizes the risk of failure or hazards during repairs.

Using authorized items helps maintain compliance with safety regulations and warranty stipulations, and ensures the reliability and effectiveness of the repairs. Technical data provides crucial information on specifications, so utilizing these verified resources is vital in maintaining the integrity of electrical items.

In contrast, the other options present risks or lack the assurance of quality. General approval items may not be suitable for specific repairs, any available tools might not meet the necessary standards, and homemade tools and materials can compromise safety and functionality. Therefore, relying solely on items specified in technical data or by the manufacturer guarantees that the repairs will be performed correctly and safely.
