The HSM SP 4040 V shredder-baler takes your documents and breaks them down into security Level 3/P-3, 1/4"x 2"particles. The generous 17" feed opening allows for an array of paper to be fed. This impressive combination device promises efficiency, shredding and pressing your materials at the same time. How does it work? Materials can be simply laid on the loading table and the electric conveyor belt takes care of the rest. Instead of feeding your documents, your materials are pulled into the opening and almost immediately broken down. The result: 15.75"L x 19.68"W x 23.62"H perfect bales. How will you know when your bale is completed? A handy "bale ready" alert will display for the user, indicating the job is complete. This document shredder features a user-friendly keypad for continuous or reverse operation. Like any shredder, a paper jam is surely inevitable. Luckily, the HSM SP 4040 V powers through paper jams by automatically reversing until the problem is remedied. Guarantee a longer lifespan for your shredder baler thanks to the integrated, manual oiler, which allows you to maintain the machine at your convenience.
