Frequently Asked Questions - CleanTEC 51422 Dahle

How to change the fine dust filter?

When the filter change indicator illuminates, unplug the shredder. Undo the screw on the rear, press the catch, remove the cover, take out the old filter, insert a new DAHLE fine dust filter, close the cover, tighten the screw, plug in, and reset the indicator by holding Forward and Reverse buttons for 5 seconds.

How to oil the shredder?

For cross-cut models (P5, P6, P7), fill the integrated oil tank with DAHLE document shredder oil. For other models, oil manually when performance drops: switch off, apply oil across the cutting rollers, then run in reverse for 10 seconds without paper.

What to do if paper jams?

The shredder automatically reverses briefly. If jam persists, press the Reverse button to eject paper. Remove excess paper, reduce the sheet count, and feed again. Do not alternate Forward and Reverse rapidly.

How to reset the filter change indicator?

After replacing the fine dust filter, plug in the shredder and switch it on. Press and hold the Forward and Reverse buttons simultaneously for approximately 5 seconds until the indicator turns off.

Why is the shredder not starting?

Check that the mains cable is plugged in, the main switch is on, the On/Off/Stop button is pressed, the door is closed, the collection bin is not full, the motor is not overheated or overloaded, and the thermal cut-out is set to ON.

How to shred CDs or DVDs?

Move the compartment for CDs/credit cards to the rear of the collection bin. Close the door, switch on, and while holding the Forward button, insert the CD/DVD into the center of the feed. Wear protective goggles.

How to empty the collection bin?

When the bin full LED flashes, switch off the main switch and unplug. Remove the collection bin, empty it, refit it, plug in, and switch on. For CDs/credit cards, empty the separate compartment.

What is the energy-saving mode?

If the shredder is not used for approximately 30 minutes, it automatically switches off (LED off). To resume, press the On/Off/Stop button.

What safety precautions should be taken?

Read the manual before use. Keep hands, hair, and clothing away from the feed. Wear protective goggles when shredding CDs/DVDs. Do not open the machine. Use only DAHLE oil. Ensure proper ventilation and stable placement.

How to install the transport lock?

Before moving the shredder, open the door, remove the collection bin, and insert the transport lock screws into the base plate under the shredding mechanism. Refit the bin and close the door. Remove the lock before use.
