If a manufacturer’s instructions need alteration, what is the initial step required?

The correct answer is to contact the manufacturer for approval before making any alterations to the manufacturer's instructions. This step is crucial because the manufacturer is the most knowledgeable entity regarding the specific details and operational parameters of their product. By seeking their approval, you ensure that any modifications align with the intended design and safety protocols set forth by the manufacturer.

If the alterations are not approved, it can lead to safety hazards, product malfunctions, or even voiding warranties. Additionally, manufacturers may have specific guidelines for modifications that ensure compliance with regulations and standards. Hence, contacting the manufacturer is the appropriate and responsible first step in this scenario.
