Frequently Asked Questions
Is the Turbo faster than the standard SS4?
No, and the name is misleading. KOBRA rates the Turbo at 8 ft/min feed speed against 22 ft/min for the standard 240 SS4. What the Turbo gains is stack capacity: up to 30 sheets per pass instead of 26. It is geared for torque, not travel. Choose it if your users feed generous handfuls and you want fewer jams; choose the standard SS4 if a single operator feeds steadily and you want the job finished sooner.
Does the Turbo shred to a different security level?
No. Both the SS4 and the SS4 Turbo cut a 1/8 inch strip and both are rated P-2 O-2 T-2 E-2 under ISO/IEC 21964 (DIN 66399). If you need a higher level, changing model within the strip-cut range will not get you there: the KOBRA 240 SS2 reaches P-3 with a 1.9 mm strip, and anything above that requires a cross-cut or micro-cut head such as the KOBRA 240.1 C4 or 240.1 C2.
Can I really put 30 sheets in at once?
Thirty is KOBRA's maximum with good paper in good conditions, and KOBRA notes on the datasheet that capacity varies with paper weight, quality, grain, supply voltage and temperature. Treat the low twenties as your everyday comfortable load on US 20 lb bond and keep 30 for light paper. Overfeeding on any shredder is the usual cause of jams; the point of the Turbo is that the margin for error is wider, not that the limit is soft.
Can it shred staples, clips and CDs?
Staples and standard paper clips yes — KOBRA specifies carbon hardened knives unaffected by them. Binder clips, bulldog clips and binder mechanisms no. CDs, DVDs, floppy disks and chip cards yes; feed discs individually rather than buried in a stack of paper. A separator inside the bin keeps the plastic fragments apart from the shredded paper.
What is the duty cycle before it needs to cool down?
There is no cool-down period. KOBRA specifies a 24 hour continuous duty motor with thermal protection, so the machine is rated to run all day. In real use the constraint is the 9.5 gallon bin rather than the motor.
Does it need bags?
No. KOBRA states the 240 series does not require plastic bags; the waste bin slides out of the cabinet without lifting the cutting head and is tipped directly into recycling. None is supplied. A standard 35 litre liner will fit if your building insists on bagged waste.
