Frequently Asked Questions
What does oil-free actually mean - do I ever need to lubricate it?
No. The 50310 is built so the cutting cylinders do not require added lubricant, and Dahle describes it as maintaining performance without that maintenance. You do not need oil bottles, and you do not need lubricant sheets - which are in any case a poor idea in most shredders because the paper backing can build up. Do not add Dahle 20721 or 20722 oil to this machine; it is not designed for it.
Is P-3 secure enough?
It depends what you are shredding, and the honest answer for most businesses is: not for everything. DIN 66399 P-3 allows particles up to 320 mm2, and the 50310 produces around 189 mm2. That is fine for routine internal paper where the risk is casual rather than deliberate reconstruction. For personal data, financial records, HR files or anything covered by a client confidentiality clause, P-4 is the normal expectation - which is the Dahle 50314 in the identical cabinet.
Can it shred CDs, credit cards and stapled documents?
Yes to all of them. Dahle rates the 50310 for CDs and DVDs, credit cards, staples and paper clips as well as paper. Feed discs and cards one at a time rather than in a stack. Even though the machine handles metal, staples and clips are still abrasive, so a constant diet of heavily stapled paper will shorten cylinder life - although the cylinders here carry a lifetime warranty, which softens that concern.
Will legal or tabloid paper fit?
No, not unfolded. The feed opening is 10.25 inches, sized for letter paper fed long-edge first. Legal (8.5 x 14) and tabloid (11 x 17) sheets will not enter without folding, and folding a sheet in half doubles its thickness, so your effective 20-sheet capacity drops accordingly. If legal paper is routine, look at Dahle's 12-inch and 16-inch throat models.
How many people can share it, and how often will the bin fill?
Dahle positions it for two to four users. Because P-3 particles are relatively large and do not compact the way micro-cut waste does, a 23-gallon bag actually holds fewer shredded sheets than the same bin on a P-6 machine - so expect to change bags a little more often than the security level might suggest. Dahle 20725 bags fit; they are not supplied with the machine.
Is it quiet enough to sit next to desks?
Yes. At 46 dB it is the quietest machine in this whole group - below the 47 dB of the high-security 40330 and well below the 64 dB of the 20396 high-capacity model. 46 dB is around the level of a quiet room with background hum, so it will not interrupt a phone call at the next desk.
