It's best never to push your machinery to its limits. You'll desire to make sure you're informed about the performance specifications of your own machinery. Ensure you don't rise above those limits. If you, you can end up causing damage to the machinery.
You should look at what exactly you need through your machinery prior to you making an order. Ensure that you choose equipment with specifications that provide what you need. When you put a lot of stress on the machinery you're working together with, you might find yourself reducing the lifespan of this equipment.
