- Mounting Brackets: Attach the main mounting brackets to the vehicle's chassis frame using the provided hardware. Ensure correct orientation and secure with specified bolts.
- Attach Tow Bar Arms: Connect the tow bar arms to the mounting brackets. Use M12 and M10 bolts, tightening them to the specified torque values.
- Mount Tow Ball Assembly: Attach the tow ball neck and ball mechanism to the tow bar. Ensure it is correctly seated and locked.
- Final Assembly: Secure the main tow bar structure to the chassis using the remaining bolts (e.g., M8 bolts).
- Electrical Connection: Connect the vehicle's electrical harness to the tow bar's socket, following vehicle-specific wiring diagrams.
- Final Checks: Verify all bolts are tightened to the correct torque specifications. Check that the tow ball mechanism operates smoothly and locks securely. Ensure all required clearances are met ⚠️.
Important Checks:
- 0km / 1000km Check: After installation (0km) and after initial use (1000km), check the tightness of all bolts ?.
- Tow Ball Locking: Ensure the tow ball is properly inserted and locked into its housing. A green indicator ✔️ typically signifies correct locking, while a red indicator ❌ or no lock signifies an improper state.
- Clearance Check: Verify that the tow ball neck and housing meet the minimum clearance requirements specified by ECE-R 55.
