Answer :
Final answer:
The trailer supply valve should not be moved until the entire air system is fully pressurized to ensure the air brakes function properly and safely.
Explanation:
After pushing in the trailer supply valve, you should not move the tractor until the whole air system is fully pressurized. This is critical for the safe operation of the air brakes on both the tractor and the trailer. The air pressure must build up to the manufacturer's specified pressure to ensure that all brake components function optimally. When dealing with air brake systems, it's important to allow time for the air compressor to build up the necessary pressure so that brakes are fully responsive when applied. If the system is not fully pressurized, the brakes may not function properly, which could lead to unsafe driving conditions.
Final answer:
After pushing in the trailer supply valve, you should not move the tractor until the whole air system is Fully pressurized.
Explanation:
After pushing in the trailer supply valve, you should not move the tractor until the whole air system is Fully pressurized.
This ensures that the brakes and other air-powered components in the trailer will function properly.
Moving the tractor before the system is fully pressurized can result in decreased braking performance and other safety concerns.
