MAINTENANCE

Step 4 – Installing the 5th wheel head

Periodically apply a light coating of grease to the the surface of the half- round rails and penetraiting oil to the locking bar (using the access holes on to the top side of the cross tube) and the four hex bolts and rollers.

Prior to towing, ensure all components and hardware are structurally sound and secure. Periodically check the torque to ensure no fasteners have become loose.

Step 5 – Maneuvering

Incomplete carriage cycle:
Return the carriage back to the previous position and reset the handle. Check the locking bar is free-moving and clear of any debris. Attempt to maneuver the carriage to the opposing lock position, ensuring the handle returns to the locked position.

If handle does not reset:
Ensure the carriage has travelled to the opposing lock position and manually reset the handle to the lock position. Visually inspect the spring located under the cross tube. Check the locking bar is free-moving and clear of any debris.
