HELPFUL TIPS TO AVOID PAPER JAMS. NEVER shred more than 6 A4 sheets of 70gms paper at the same time, otherwise the extra paper will jam the Shredder. If you are shredding A4 Sheets that are thicker than 70gms, you will need to reduce the number of sheets being shredded, otherwise the Shredder will jam. When shredding paper, always leave a few seconds gap between the shredding of the last sheet/s and the shredding of the next sheet/s. This is to ensure that the previous sheet has been fully shredded and the blades are completely paper free. Once you have finished shredding paper, move the switch between REV and OFF several times.
