An automatic oil injection system can be one the best additions to a new or existing shredder. With the exception of strip cut models, all varieties of shredders require careful maintenance and regular oiling. Having a properly oiled cutting shaft keeps the machine in top shape in a number of ways. Automatic oilers take all the guesswork and inconvenience out of manual oiling. They quickly and automatically detect when the cutting shaft needs oil and then apply the perfect amount. A perfectly-oiled cutting shaft keeps your shredder running as efficiently as possible so you get the most out of it. It also keeps your shredder in better condition all together, prolonging its life and reducing potential maintenance or replacement costs down the road.
