Question: A technician is using bottle jacks to support a stable machine component for repair. After lifting the component to the required height, what is the best practice for ensuring the load's long-term stability and safety?

Answer options: ✅ Place appropriately rated jack stands under the component and lower it onto them before removing the bottle jacks.

• Leave the bottle jacks in place and occasionally check their pressure to ensure they haven't settled.
• Lower the component slightly to 'settle' the bottle jacks, then leave them as the primary support.
• Chock the component with wooden blocks for added stability, then continue working with the bottle jacks as primary support.

Correct answer: Place appropriately rated jack stands under the component and lower it onto them before removing the bottle jacks.

Explanation: Bottle jacks are designed for lifting, not for prolonged support. For long-term stability and safety, dedicated jack stands, specifically designed for supporting loads, must always be used in conjunction with or after lifting with jacks. The load should be lowered onto the stands, and only then can the jacks be removed or kept as secondary support.
