Frequently Asked Questions
Does the AF350 have a bigger bin than the AF300?
No, and this catches buyers out. The AF350 stands in a taller and deeper cabinet - 435 x 837 mm against the AF300's 381 x 740 mm - but the waste bin is the same 35 litres, about 9.2 gallons. The extra size accommodates the larger 350-sheet feed tray, not more waste capacity. You are buying fewer reloads, not fewer bag changes.
How long does a full 350-sheet tray take to shred?
HSM does not publish a run time for a full tray, and it varies with paper weight, how well the stack is fanned and whether fasteners are present, so any figure quoted would be a guess. What is fixed is that the machine works through the stack on its own and stops when the tray is empty. Plan to load it and do something else rather than waiting for it.
Can it shred CDs, DVDs or credit cards?
Credit cards yes, one at a time through the manual slot. CDs and DVDs no - this configuration is rated E-4, F-2, P-5 and T-5 with no optical media class, so HSM does not list discs among the materials it accepts. If disc destruction matters, the AF350 in 3/16 inch x 1 1/8 inch is rated O-3 for optical media, at the cost of dropping from P-5 to P-4.
Is this shredder NSA approved?
No. NSA/CSS Specification 02-01 requires a maximum 1 mm x 5 mm particle and requires the specific model to be named on the NSA Evaluated Products List. This is a P-5 machine at 1.9 x 15 mm and it is not on that list. No SECURIO AF model is. If you are destroying classified material you need a listed P-7 device, and a high DIN class is not a substitute.
Will legal-size paper fit?
Yes. The throat is 9.45 inches (240 mm) wide, and both US letter and legal are 8.5 inches on the short edge, so they feed flat. Tabloid at 11 inches will not fit unfolded; folding it once halves your effective sheet capacity for that pass. The automatic tray is designed around standard letter and A4 stacks and works most reliably with paper of a consistent size.
Can it shred stapled documents?
Yes. HSM rates the machine for paper containing staples and paper clips, and the cutting rollers are solid steel and induction hardened. Through the automatic tray, avoid thick stapled bundles - the sheet separator can bind on a heavy staple - and put those through the manual slot instead. Ring binders, bulldog clips, laminated sheets and plastic wallets must always be removed.
Does it need oiling, and is an oiler built in?
There is no automatic oiler on this model, so oiling is a manual task. P-5 cutting heads shed fine paper dust that settles on the rollers and slowly reduces sheet capacity. Apply HSM shredder oil across the width of the throat, run the machine in reverse for a moment, then feed a few sheets through. Do not use aerosol lubricant sprays or any vegetable oil.
