Why is it important to avoid overextending the jack handle?

Avoiding the overextension of the jack handle is crucial mainly because it may lead to a loss of control and an increased risk of failure or tipping. When the handle is overextended, it can create instability in the lifting process, making it difficult to maintain steady control over the load. This instability can cause the load to shift unexpectedly, which heightens the risk of the jack tipping over or failing completely under stress.

Maintaining proper control is essential for safety during lifting operations. Overextending the handle can alter the leverage and balance, contributing to a hazardous situation. This principle underscores the importance of adhering to the manufacturer's guidelines regarding handle operation and load management to ensure safe and effective use of lifting equipment.
