Frequently Asked Questions
What power supply does the 4108 need?
220 volts, three phase. This is not a machine you plug into an office wall socket - it needs a proper three-phase connection installed by an electrician, and the strip-cut configuration draws up to 10 horsepower. Confirm supply availability at the intended location before ordering. Retrofitting three-phase to a room that does not have it usually costs more than the difference between this machine and a single-phase alternative.
Is a P-2 strip cut acceptable for confidential documents?
Only for low-sensitivity material. DIN 66399 P-2 permits strips up to 6 mm wide, which preserves complete lines of readable text. It is appropriate for internal administrative paper, obsolete forms, print overruns and general paper reduction. It is not appropriate for anything containing personal data, financial account details or client information - specify the cross-cut DSH0348 at P-3, or a 4606 at P-5, for those.
How does the conveyor change how it is used?
It changes shredding from an attended task to a loading task. You place a stack on the wide feed table and the powered belt carries it into the 16.2-inch throat at a controlled rate, with automatic reverse and re-feed if a jam starts to form. MBM states the conveyor system maintains high work speed without creating paper jams. In practice, one operator can keep the machine fed while doing other work nearby.
Do I have to oil it?
The 4108 has an electronic oil injection system that lubricates the cutting shafts automatically during operation, so there is no daily manual oiling routine. You still need to keep the oil reservoir topped up with proper shredder oil, and you should still inspect the cutting head periodically. Automatic oiling reduces maintenance labour; it does not eliminate maintenance.
How much space does it need?
The machine measures 67 inches deep by 48.75 inches wide and 56.75 inches high, and you need working room beyond that: space at the feed table for an operator and a stack of paper, and clearance at the rear door so the wheeled bag frame can be pulled out. Allow roughly a 10 by 8 foot area in total. It weighs 787 lb, so check floor loading and the route in.
How often will the 79-gallon compartment fill?
Faster than the volume suggests, because strip-cut waste is bulky and does not settle. At anything approaching the rated feed rate, expect to change bags at least daily. The wheeled pull-out bag suspension is designed for exactly that - the full bag rolls out rather than being lifted. If bag changes become the bottleneck, that is a sign the strip-cut configuration is being used at the top of its range.
How does it compare with the cross-cut 4108?
Identical chassis, conveyor, feed opening and 79-gallon compartment. The DSH0348 cuts 6 x 50 mm at DIN P-3, takes 65-82 sheets and uses an 8 hp motor; this one cuts 6 mm strips at P-2, takes 75-95 sheets and uses 10 hp. You are trading about 13 sheets a pass for a security level. For most organisations that trade is worth making.
