You should start by checking the air in the tire. One thing that you should do is to make sure that the tire has enough pressure. One thing that you should know is that the inflation level of the tire will determine whether it is going to last long or not. When the air is not enough in the tire you will realize that the tire wears out within a short period of time. You can achieve this by using the tire monitoring system to inspect the pressure and the leaks.
Apart from that you should also monitor suspension. You should do this visually by looking for signs of irregular wear, tear or heat cracks that may be found on the springs. In one way or the other it is your duty to make sure that there is nothing that is neither touching the suspension or interfering with its functionality. Apart from that, you should also make sure that the springs have equal and sufficient pressure. It is important that you moderate the riding height since when it is too low or too high it will interfere with safe navigation of the overpasses. This is because you may find that the trailer will damage the components of the suspension when there is little air since it rides on the suspension bumper instead of air bag.
Another thing that you should do is to lube it correctly. You should make sure that you apply the correct lube at the right amount as this is essential for the operation of the trailer. Application of grease in the right amount is important as it will prevent the tear and wear of the moving parts. You can do this by crawling under the to identify some of the parts that need to be greased.
Apart from that, you should also make sure that the trailer has a proper lighting system which can serve it fully. You should do this regularly by checking at the wires, lamps and the harness system. Not only that but it is also important that you replace the grease at the connection points to prevent the tear and wear. The electrical system of the tractor is always damaged by the corrosion that is always caused by the liquid and the salt that is always used to de-ice the roads. The last thing that you want is to be stopped by the road side because of poor lighting system yet you might be running out of time.
Another important thing to check is the tractor security. It is important that you check the ties down straps, chains and the ratchets. Not only that, but you should also check the holes, snags, tears and cuts, loose switching. Including the loose logistics from the inside.
