Final answer:
The correct answer is option 3) Chock the wheels of the tow truck.After putting the tow truck transmission in neutral and activating the PTO, the next immediate step is to chock the wheels of the tow truck for safety and stability.
Step-by-step explanation:
After putting the tow truck transmission in neutral and activating the PTO (Power Take-Off), it is important to chock the wheels of the tow truck. Chocking the wheels involves placing a wedge or block in front and behind the tires to prevent any movement. This ensures the safety and stability of the tow truck while performing the lift.
Lowering the wheel lift (option 1) and starting the lift (option 4) are steps that come after chocking the wheels. Setting the parking brake on the disabled vehicle (option 2) is not necessary, as the neutral setting on the tow truck transmission already prevents any accidental movement.After the tow truck transmission is put in neutral and the Power Take-Off (PTO) is activated, it is important to ensure the tow truck remains stationary before beginning the process of lifting the vehicle. To prevent any accidental rolling or movement of the tow truck, wheel chocks should be used. These are wedges of sturdy material placed against the wheels of the tow truck to prevent accidental movement. Once the tow truck is secure, you can safely proceed with the other steps of the towing process, such as lowering the wheel lift, setting the parking brake on the disabled vehicle, and starting the lift operation. Ensuring safety during the towing operation is paramount, hence why securing the tow truck is a critical step.
