How to install Swingline 350MD Medium Duty Electric Punch

• Choose a stable, level workspace with easy access to an electrical outlet compatible with standard office power.
• Unbox the unit and place it on the desk or counter where it will be used most frequently, ensuring there is ample clearance for paper feeds and waste disposal.
• Connect the punch to a suitable power source. If the model requires a specific outlet or adaptor, use the manufacturer’s recommended configuration to avoid electrical issues.
• Open the chip tray to confirm there is no debris or loose pieces inside, then close it securely before loading paper.
• Align the paper stack to the edge guides, ensuring the sheets are flat and within the device’s capacity limit (up to 50 sheets). For best results, remove any wrinkled or torn pages that could cause jams.
• Feed the aligned stack into the punch until it rests against the back stopper, then press the push button firmly and evenly to punch a clean set of holes.
• Release the button and check the punched sheets for clean holes. If a misfeed occurs, switch to jam reversal and gently back out the paper, then reinsert after clearing the path.
• Tip: Periodically empty the chip tray during extended use to maintain consistent punching performance and avoid overflow.
