How Do You Adjust the Airbags on a Semi Truck?

Truckers must ensure that the airbags on their semi-trucks are properly adjusted in order to ensure a safe ride. Airbags are an important safety feature of any vehicle, and when it comes to semi-trucks, it is especially important to make sure that you have taken the necessary steps to ensure they are adjusted correctly. It is essential that you understand the process of adjusting your airbags so that you can do so safely and remain in compliance with safety regulations.

The first step in adjusting the airbags on a semi-truck is to identify the type of airbag system used. There are three main types: mechanical, hydraulic, and electronic.

Knowing which system your truck has will help you determine how to adjust it properly. Once you have identified your type of airbag system, consult the owner’s manual for specific instructions on adjusting it.

Mechanical Airbag Systems

Mechanical airbag systems are typically found in older model trucks and require manual adjustment by turning a knob or lever located either beneath or beside the steering wheel or near the accelerator pedal. To adjust this type of system, turn the knob or lever clockwise until it reaches its desired pressure setting.

Hydraulic Airbag Systems

Hydraulic airbag systems are most common in newer model trucks and require adjustment with a special tool called an “air wrench.” This wrench is inserted into a valve located between the frame and cab of your truck.

Turning this valve counterclockwise will reduce pressure while turning it clockwise will increase pressure. The desired pressure setting should be listed in your owner’s manual.

Electronic Airbag Systems

The electronic airbag system found in some newer model trucks uses sensors to monitor road conditions and automatically adjust the pressure accordingly. This system requires little to no manual adjustment as long as all components are functioning correctly.

Conclusion:

Adjusting the airbags on a semi-truck takes knowledge of the specific type of system used as well as careful attention when making adjustments. Knowing what type of system your truck has and consulting its owner’s manual for accurate instructions is essential for ensuring that your truck remains compliant with safety regulations while providing maximum protection for you and any passengers.
