Verify model matching and prepare tools (wrenches, torque wrench, jack). Select a flat, solid site and inspect all components for defects before starting.
Position the tractor and trailer. Install the base to the frame, hoist the main body, align hole positions, and tighten bolts using a diagonal pattern to specific torque.
Align the traction pin and reverse slowly until locked. Always check connection status visually before driving. Use landing gear before unlocking for separation.
Regularly check locking mechanisms and wear monthly. Overloading is strictly prohibited. Inspect bolts after driving on rough roads.
