Motor Saver has a new pre-filter called, Outer Saver Pre-Filter. The Outer Saver pre-filter has been designed to repel dirt from your oil foam filter allowing your more run time between cleaning the foam filter. The new Outer Saver pre-filter also helps repel moisture, keeping your foam filter dryer for longer periods of time.
The Outer Saver pre-filter is attached to your foam filter using an easily adjustable cord with the touch of a button. The lead ropes coming out of the lock are short so they do not interfere with any linkage or gearing.
