Regular lubrication of someone's shredder cutters is essential to maintain peak shredding performance. Fellowes paper shredder oil lubrication sheets conditions the cutters to extend the life of someone's shredder. For the best results, it is important to oil someone's shredder each time someone empty the wastebasket or a minimum of twice a month. To oil someone's shredder, simply feed the lubrication sheet into the paper entry and release (someone may need to use more sheets for paper shredders with a wider paper entry). Once the lubrication sheet has been shredded, run the shredder in reverse for 2-3 seconds and simply repeat the instructions when someone empty someone's paper waste bin again. Do not use aerosol oils to lubricate someone's shredder. Such lubricants are petroleum-based and can be a serious fire hazard. the Fellowes product contains 10 paper shredder oil lubricant sheets to help maximise shredding performance.
