Frequently Asked Questions
Is the 707 PS actually NSA approved, or does it just meet the particle size?
Both. Its 1 x 5 mm particle meets the NSA/CSS 02-01 requirement of 1 mm by 5 mm or less, and the model appears by name as '707PS' on the NSA/CSS Evaluated Products List for paper shredders, carrying a High volume rating. That distinction matters: a P-7 rating alone does not make a shredder NSA approved. Always check the current quarterly EPL revision before you certify a machine for classified work, because listings do change.
How many sheets can it take at once?
Eleven sheets of #20 bond, or thirteen sheets of lighter #16 bond, on 8.5 x 11 in paper. Those are Dahle's own published figures. Plan around eleven. P-7 cutting heads work hard for every sheet, so capacity is low by design across every high security shredder on the market - that is the trade-off for a 5 mm2 particle, not a shortcoming of this machine.
Can it shred staples, paper clips or credit cards?
Dahle lists paper as the accepted material for the 707 PS and does not list staples, paper clips or cards. A P-7 head has very fine tolerances and metal is the fastest way to damage it. Remove fasteners before feeding. If your workflow genuinely cannot separate clips from documents, a P-4 or P-5 machine built to tolerate them will cost you far less in cutting-head repairs.
Will legal or tabloid paper fit?
Legal size fits comfortably. The throat is 16 inches wide, so 8.5 x 14 in legal sheets go in on the short edge with room to spare, and 11 x 17 in tabloid also fits on its 11-inch edge. Sheet capacity figures are quoted for 8.5 x 11 in stock, so expect fewer sheets per pass on larger sizes because there is more paper crossing the cutting head.
How often will the 53-gallon bin need emptying?
More often than the number suggests. A 5 mm2 particle is close to dust and packs densely, but P-7 output also traps a lot of air until it settles. In practice a 53-gallon bin is a full working day for a small team feeding it steadily. Empty it before it packs solid against the head - a compacted bin is a common cause of nuisance jams on high security machines.
Does it need oiling by hand?
No. The automatic EvenFlow Lubricator® feeds oil across the cutting cylinders continuously while the machine runs, so there is no manual oiling schedule to enforce. You do need to keep it topped up with lubricant, which is a consumable. Skipping refills on a P-7 head is not a minor omission - the fine cut depends on constant lubrication and running dry will shorten cylinder life.
What electrical supply does it need?
A standard 115 V supply. That is unusual for a 320 lb, 3.5 HP shredder and it is one of the practical reasons to choose the 707 PS: no electrician, no three-phase drop. By contrast the PowerTEC 828 HD, 909 HS, 919 IS and 929 IS all require 220 V three-phase. Dahle does not publish a circuit amperage for the 707 PS, so confirm the breaker rating with your dealer if the outlet is shared.
How loud is it in a shared office?
55 dB, which is around the level of ordinary conversation and quiet for a machine this size. Rubber shock mounts and the chain drive keep vibration down. It is not silent under a full 11-sheet load, but it will not dominate a records room the way the 65 dB 919 IS or the 70 dB 929 IS would.
