Frequently Asked Questions
Why does a P-7 machine need an automatic oiler more than other cuts?
A 1 x 5 mm cutting head has more cutting edges engaged at once and far tighter clearances than a strip or cross cut, so it runs hotter and dries out faster. Oil keeps the particles releasing cleanly and stops the motor working against friction. Manual oiling is possible, but on a high-security machine used by several people it tends not to happen until performance has already degraded.
Does the oiler need refilling, and how often?
Yes - it is fed from a replaceable oil bottle, so it is a consumable cost, not a fit-and-forget feature. HSM does not publish a refill interval, which depends entirely on how much you shred. Plan to keep a spare bottle of HSM shredder oil on hand and check the level when you empty the bin.
Is a bottle of oil supplied with the machine?
We could not confirm this from HSM's published documentation. Assume it is not included and order HSM shredder oil alongside the machine. Use HSM's own oil rather than a generic lubricant - the wrong viscosity can leave residue on the rollers.
How much space does the oiler version need?
Overall width goes from 497 mm to 547 mm, roughly two extra inches. Depth stays at 398 mm and height at 793 mm. Allow clearance on the oiler side for bottle changes, and remember the waste container pulls forward out of the cabinet.
Is this NSA approved?
We have not verified an NSA Evaluated Products List entry for this model. NSA/CSS 02-01 requires both a maximum 1 mm x 5 mm particle and current EPL listing; this machine meets the particle-size requirement but that alone is not approval. If you are destroying classified material, confirm the current EPL before purchase rather than relying on the DIN rating.
Can I put stapled documents in?
No. HSM lists paper as the only material for this model, and the fine tolerances of a P-7 head make metal fasteners a real risk. Remove staples and clips first. If your workflow cannot accommodate that, the P-6 version of the B32 at 0.78 x 11 mm is rated for staples and paper clips and takes six sheets a pass.
Does the lifetime roller warranty apply to this machine?
No. HSM's lifetime cutting-roller warranty covers security levels P-2 to P-5, so a P-7 model is outside it and the rollers fall under the standard machine warranty. That is a genuine consideration when comparing a P-7 purchase against a P-5 one. We were not able to verify the standard US warranty period from HSM's published material.
