To ensure safety during operations, the collar locking knob should be:

The collar locking knob should be hand or wrist tight to ensure safety during operations. This level of tightness ensures that the locking mechanism is secure without being over-tightened, which could potentially damage the equipment or lead to operational failure.

Achieving the right tightness through hand or wrist pressure allows operators to maintain control over the weapon while minimizing the risk of unintentional disengagement. This is crucial for preventing accidents during handling and firing. Proper tightness also aids in the alignment of the weapon system, ensuring it functions correctly while being used.

While checks for corrosion, proper lubrication, and resistance to overheating are important maintenance practices for overall equipment safety and performance, they do not directly relate to the immediate safety aspect of securely locking the collar in place during operations. Proper attention to the tightness of the collar locking knob is a fundamental step in ensuring safe handling and reliable function of the equipment.
