Final answer:
When there is a small gap between the vehicle and the jack stands, you should check if the jack stands are under solid, load-bearing parts, set as low as possible, and if the lift and the vehicle are able to move freely upward.
Step-by-step explanation:
When there is a small gap between the vehicle and the jack stands and you are ready to lower the lift further, there are a few things you should check beforehand. One important thing to check is whether the jack stands are placed under solid, load-bearing parts of the vehicle. This ensures that the weight of the vehicle is properly supported and distributed.
Another thing to check is whether the jack stands are set as low as possible. This ensures that the vehicle is stable and prevents any unnecessary movement while working on it. Lastly, you should also check whether the lift and the vehicle are able to freely move upward. This is important to ensure that there are no obstructions or restrictions that could cause damage or accidents when lowering the lift further.
