Frequently Asked Questions
Why does the S5 shred more sheets than the S4?
Because it cuts wider strips. The S5 uses a 5.8 mm strip against the S4's 3.8 mm, which means fewer cutting edges engaging each sheet and less work per pass for the same 500 W motor. The result is 30 to 32 sheets at 70 g/m2 instead of 27 to 29. Both machines are rated P-2, so the difference is throughput and fragment size, not security class. Everything else about the two is identical.
What paper weight are the sheet figures quoted at?
Kobra quotes two figures: 30 to 32 sheets on A4 at 70 g/m2 and 24 to 26 sheets at 80 g/m2. US 20 lb bond letter paper is roughly 75 g/m2, so it sits between the two, and a realistic planning number for a US office is around 27 to 29 sheets. Heavier stock, glossy paper and anything folded will reduce that further. Treat published maxima as ceilings, not targets.
Will 11 x 17 tabloid sheets fit?
Yes. The throat is 12.2 in (310 mm) wide, so tabloid feeds in on its 11 in edge and A3 feeds short edge first. Do not fold tabloid to make it fit a narrower path: a fold counts as two thicknesses at the knives and costs you more capacity than feeding the sheet flat. Sheet capacity figures are quoted for A4, so reduce the stack when feeding larger formats.
How loud is it in an open-plan office?
Kobra rates it at 54 to 55 dB(A), which is at the quieter end for a machine of this throughput and is roughly the level of normal conversation. It will be noticed in a quiet room but does not dominate it. The Energy Smart standby also helps: the machine drops out of readiness after eight seconds of inactivity rather than idling, so it is silent between uses instead of humming.
How often will the bin need emptying?
Strip-cut waste is bulky and springy, so the 29-gallon (110-litre) cabinet fills with fewer sheets than the same cabinet would hold as cross-cut waste. A department putting a few hundred sheets a day through it should expect to empty roughly twice a week. If your bin seems to fill absurdly fast, it is usually air rather than paper; pressing the waste down before it reaches the sensor buys a meaningful amount of extra capacity.
Is the 270 TS S5 NSA approved?
No. NSA/CSS Specification 02-01 requires a particle no larger than 1 mm x 5 mm and the specific model has to appear on the NSA Evaluated Products List for Paper Shredders. The 270 TS S5 cuts at 5.8 mm strips and is rated P-2, so it does not meet either condition and must not be used to destroy classified national security information. Kobra's models that are on the current EPL include the 300 HS-6 and the 270 TS HS-6, both of which cut 0.8 x 5 mm.
What warranty covers this machine in the US?
We do not publish a US warranty term on this page because Kobra's US warranty is set by the importing distributor rather than printed on the factory datasheet. Kobra's UK distributor publishes two years on the machine and ten years on the cutting blades (parts only) for this chassis, which is a reasonable guide to the factory position but not a US commitment. Ask us for the warranty document that ships with your unit before you order, and we will send the current terms in writing.
