3. Installation (Blade Replacement)
The Einhell 3405930 is a replacement blade for the Einhell GH-KS 2440 shredder. Follow these steps to replace the blades:
- Prepare the Shredder: Ensure the Einhell GH-KS 2440 shredder is turned off and completely disconnected from the power supply. Allow any moving parts to come to a complete stop.
- Access the Blade Compartment: Refer to your main GH-KS 2440 shredder manual for specific instructions on how to safely open and access the blade compartment. This usually involves removing covers or opening latches.

4. Operation
Once the new Einhell 3405930 blades are correctly installed, the shredder will be ready for operation. The blades are the primary cutting component responsible for reducing garden waste. Always operate the shredder according to the instructions provided in your main Einhell GH-KS 2440 shredder manual. Ensure that only appropriate materials are fed into the shredder to prevent damage to the blades and the machine.
5. Maintenance
Proper maintenance extends the life of your shredder blades and ensures optimal performance:
- Regular Inspection: Periodically inspect the blades for signs of wear, dullness, or damage. Replace blades when they become dull or chipped to maintain shredding efficiency and prevent strain on the motor.
- Cleaning: After each use, and with the power disconnected, carefully clean any debris, sap, or residue from the blades and the blade compartment. A stiff brush or compressed air can be used.
- Storage: Store replacement blades in a dry, safe place, away from moisture and corrosive materials. Keep them in their original packaging or a protective container to prevent accidental injury and maintain their sharpness.
- Lubrication: If recommended by the main shredder manual, apply a light coat of machine oil to the blades to prevent rust, especially during long periods of storage.
6. Troubleshooting
If you experience issues related to shredding performance after installing new blades, consider the following:
- Poor Shredding Performance: If the shredder is not cutting effectively, the blades may be dull or incorrectly installed. Inspect the blades for sharpness and ensure they are oriented correctly and securely fastened.
- Unusual Noise/Vibration: This could indicate loose blades or improper installation. Immediately disconnect power and re-check all blade fasteners and seating.
- Blade Damage: If blades are chipped or bent, they must be replaced immediately to prevent further damage to the shredder or potential injury.
For issues not related to the blades, refer to the main Einhell GH-KS 2440 shredder manual.
