Frequently Asked Questions
Can this shred staples and paper clips?
Yes. HSM lists staples and paper clips as accepted materials for the B24 at 4.5 x 30 mm, so you can feed stapled documents straight in without stripping them first. Heavy binder clips, spiral bindings and ring-binder mechanisms are a different matter — remove those. Repeatedly feeding metal fasteners is normal use, but it is also the reason the automatic oiler on this version is worth having: well-lubricated cylinders shrug off fasteners that a dry cutting head will drag on.
How is this different from the B24 without the oiler?
Mechanically, nothing. Same 610 W motor, same 240 mm throat, same 35 L bin, same 4.5 x 30 mm cut. The oiler version carries an oil bottle on the side of the cabinet that meters lubricant onto the cutting cylinders automatically. In practice that means sheet capacity stays at the rated 14-16 rather than sagging between manual oiling sessions, and nobody has to remember a maintenance task. Allow a little extra side clearance for the bottle.
How often will the bin need emptying?
HSM rates the 35 L bin at roughly 415 sheets of 80 g/m² paper at this cut size. A single user clearing a few files a day might empty it weekly; a five-person team running it in continuous operation will be at it two or three times a week. If that sounds like too much handling, the B26 chassis (55 L, about 672 sheets at the same cut size) or the B32 (82 L) is the better buy.
Is this NSA approved?
No. NSA/CSS 02-01 requires a maximum particle of 1 mm x 5 mm and the specific model must appear on the NSA Evaluated Products List. This machine cuts 4.5 x 30 mm, which is an order of magnitude coarser, and it is not listed. P-4 is the right level for ordinary confidential commercial paper under DIN 66399, not for classified national-security material. If you have an NSA requirement, ask us before ordering — nothing in the B24 range meets it.
What bags fit this model?
HSM1408 shredder bags, sold 100 to a carton, rated 13 gallons. The same bag fits the HSM Classic 108, AF150 and AF300, so a mixed HSM fleet can standardise on one part. The larger HSM1815 bag used by the B26 and B32 will not sit correctly in the B24’s 35 L bin. Bags are not supplied with the machine.
Will legal or tabloid paper fit?
Legal, yes — fed short edge first, an 8.5-inch width passes easily through the 9.4-inch throat, and the extra length is irrelevant to a shredder. Tabloid at 11 x 17 inches will not fit flat; fold it or feed it folded in half. If you routinely destroy 11 x 17 drawings or ledger sheets, move up to the 310 mm throat on the B26 or B32.
Does the oiler need special oil?
Use HSM cutting-block oil. Do not substitute vegetable oil, aerosol lubricants or general-purpose machine oil: aerosols are a fire risk near a shredder motor, and thicker oils gum the cylinders and attract dust. Replacement bottles are ordered separately from the machine. The oiler meters continuously in use, so consumption tracks how much paper you actually shred rather than the calendar.
