The safety and the handling of oil standing at the back of the bottle in 10 different languages.
Before first use only the aluminum cover must be removed (safety lock) from the bottle. I purely stabbed with a screwdriver a hole, which was much easier the lid fitting all right on the bottle.
The oil is odorless and nearly colorless. Suitable devices are strip cut, particle cut shredders and CD Shredder.
The usage is very simple. It spread a little oil in serpentine lines on a sheet of paper and can now run this through the shredder. The oil spread this evenly over the blades. The opening of the bottle might have even managed to be a little smaller, so you should apply careful not too much oil during the first use. Due to the amount of oil, the bottle is very economical, because I think you can get very long with out.
I guess that by the regular use of the oil, the durability of the blade is already extended. The noise level has dropped slightly at my shredder. How often you should apply the oil I have time to explore in the next few weeks itself, which is probably also vary from device to device.
All in all, to recommend the product highly.
