Frequently Asked Questions
Why is the SS2 rated P-3 when the SS4 and SS5 are only P-2?
Because of strip width. DIN 66399 and ISO/IEC 21964 rate long strip particles on width: 6 mm or narrower is P-2, 2 mm or narrower is P-3. The SS2 cuts a 1.9 mm strip, just inside the P-3 limit. The SS4 cuts 1/8 inch (about 3.2 mm) and the SS5 cuts 1/4 inch (about 6 mm), so both land at P-2. Narrower strips take more cutting work per sheet, which is why the SS2 handles 15 sheets per pass while the SS5 handles 29.
Can I leave staples and paper clips in?
Yes. KOBRA specifies carbon hardened cutting knives that are unaffected by staples and clips across the 240 series. Ordinary office staples and standard paper clips are fine. Bulldog clips, binder clips, ring binder mechanisms and anything hardened are not — those will chip a tooth. Sticky notes and laminated sheets also cause problems, laminate more than staples.
Does it need shredder bags?
No. KOBRA designs the 240 series to run without plastic liners; the waste bin slides out of the cabinet and is tipped straight into a recycling container. That also keeps the shredded paper clean for recycling, since it is not mixed with a plastic bag. If your building's waste handling requires bagged material you can line the bin with a standard 35 litre liner, but nothing is supplied and nothing is required.
Can it shred CDs or credit cards?
Credit cards yes, including chip cards. CDs and DVDs no — the SS2 is listed for paper and cards only. The SS4 and SS5 on the same chassis do carry a CD/DVD and floppy disk rating, so if disc destruction matters, choose one of those and accept P-2 instead of P-3.
How loud is it in an open-plan office?
55 dB(A), which is around the level of a normal conversation and quiet for a departmental shredder. The cross-cut models on the same chassis run at 58 to 61 dB(A). The Energy Smart standby also means it is silent between jobs rather than idling.
