6. คู่มือการใช้งาน

The CURT 45297 ball mount can be used in two primary configurations to achieve level towing:

• Drop Position: When the trailer coupler is lower than your vehicle's receiver, position the ball mount with the ball platform facing downwards to achieve a 6-inch drop. This helps level the trailer.
• Rise Position: If the trailer coupler is higher than your vehicle's receiver, flip the ball mount so the ball platform faces upwards to achieve a 4-inch rise. This also helps maintain a level towing setup.

Always ensure the trailer tongue is level or slightly nose down when coupled to the tow vehicle. This is crucial for safe handling and stability.
