Dahle Paper Shredder Lubricating Oil, 250ml, is a specific oil used for the regular maintenance of paper shredders. It is applied directly to the cutting blades to reduce friction, prevent jamming, and extend the life of the shredding mechanism. Periodic application of this oil, as indicated in the equipment manual, helps maintain the shredder's original efficiency and avoids costly repairs caused by premature wear. The 250ml container is sufficient for several applications over time. It is a recommended maintenance product for any regularly used paper shredder.
