Shredder oil extends the life of cutters by keeping them well lubricated ^^ Swingline oil is a high-performance synthetic oil that will not cause build-up on any shredder parts ^^ Oil reduces torque allowing cutters to move easily. This reduces the risk of paper jams ^^ Compatible with all Swingline shredder models as well as shredders made by other manufacturers ^^ Use on standard shredders by pouring a few streaks of oil onto a sheet of paper and running the oiled sheet through the shredder. Use on Swingline Jam Free and Stack-and-Shred shredders with a Intelligent SelfOil feature by pouring oil into the shredder's designated oil reservoir
