Frequently Asked Questions
How many people can realistically share this machine?
A working group of five to fifteen, in our experience. The 22 to 24 sheet capacity means nobody waits long, and the full-bin display with automatic shut-off is what stops a shared machine being jammed by whoever ignores a full container. HSM does not publish a formal duty-cycle rating, so if your usage is genuinely continuous for hours at a time, look at a departmental machine from the SECURIO range instead.
What does the full-bin indicator actually do?
It shows on the display that the container has reached capacity and switches the machine off automatically, so nothing is fed into a bin that cannot take it. That matters more than it sounds: on shared shredders, the most common cause of a seized cutting head is somebody continuing to feed a full machine. Empty the 35 litre container - roughly 245 strip-cut sheets - and it resets.
Does it shred CDs, credit cards and film?
CDs and credit cards yes; film is not rated on this variant. The strip-cut Pure 420 carries E-2, O-2, P-2 and T-2 classes under DIN 66399 - O for optical media, T for magnetic cards. It has no F class, which is the classification for film, whereas the cross-cut version does. Feed discs and cards singly rather than mixed into a stack of paper.
Will legal or tabloid paper fit?
Legal fits easily - the throat is 240 mm, which is 9.45 inches, and legal paper is 8.5 inches wide. Tabloid at 11 inches, or 279 mm, does not, and neither does A3 at 297 mm. Folding tabloid in half works but halves your effective capacity per pass. If unfolded tabloid or A3 is a regular requirement, the Pure 530 with its 300 mm throat is the model to buy.
Is 5.8 mm really a quarter inch?
Not quite. 5.8 mm converts to 0.228 inch, a shade under 1/4 inch. The quarter-inch figure in the product title is a rounded conversion carried over from US listings; HSM's own figure for this cutting head is 5.8 mm. It stays within P-2 either way, since DIN 66399 permits strip widths up to 6 mm at that level.
Does it need shredder oil?
Strip-cut heads are much less oil-dependent than particle-cut heads and HSM does not specify a routine oiling schedule for this variant. If throughput drops off or the cutting head starts sounding strained, apply proper shredder oil across the width of the intake and run the machine briefly in reverse. Do not use aerosol lubricants, WD-40 or cooking oil - all of them gum the head and none are covered by the warranty.
Is it NSA approved?
No. NSA/CSS 02-01 requires a maximum particle of 1 mm x 5 mm and requires the specific model to appear on the NSA Evaluated Products List. A 5.8 mm strip is nowhere near that, and the Pure 420 is not listed. Anyone with a genuine classified-destruction obligation needs a P-7 high-security shredder that carries an individual NSA listing, and we are happy to point you to those.
