Handling of getting used to, and: the oil is rancid gummy &

Anyway: Even my shredder began after a while to intensive use, powerful to dust. Therefore I bought this oil. And indeed, it is now less dusty. After initial Kleckern I also get the hang of how I best can muster the oil on the counter-rotating metal discs. How often do you have to do that, however, and how many estimated milliliters each time I reinträufeln need is me after a few weeks still a mystery. A manual would be nice (been) ...

Update December 2012:
My shredder was a few months around unused. In time, the applied oil is gummy and become rancid. The cutting system stinks like 'ne old Youping. Disgusting. Therefore two star deduction, and the oil that comes in the garbage. In future I'll WD40, as one commentator has advised.
