Setup
Before installing the grinder knife, ensure your meat grinder is unplugged and clean. Refer to your specific grinder's manual for detailed assembly instructions.
- Preparation: Ensure all grinder components are clean and dry.
- Placement: Position the grinder knife onto the grinder auger shaft. The cutting edge of the knife must face outwards, towards the grinder plate. Incorrect orientation will prevent proper grinding.
- Secure Components: Place the desired grinder plate over the knife, ensuring it sits flush. Then, secure the retaining ring or collar according to your grinder's instructions.
- Check Fit: Verify that the knife, plate, and retaining ring are securely in place and that the knife can rotate freely without excessive play.
Operating Instructions
Always follow the safety guidelines provided with your meat grinder. The LEM #10/#12 Stainless Grinder Knife is designed for efficient meat processing when used correctly.
- Safety First: Always ensure the grinder is properly assembled and secured before operation. Keep hands and loose clothing away from moving parts. Use a food pusher, not your hands, to feed meat into the grinder.
- Meat Preparation: Cut meat into appropriate sizes that fit easily into the grinder's feed tube. For best results, meat should be chilled to a near-freezing temperature.
- Grinding Process: Turn on the grinder. Slowly feed the prepared meat into the hopper. Do not force meat into the grinder; allow the auger to pull it through.
- Monitoring: Observe the grinding process. If the grinder struggles or jams, turn it off immediately, unplug it, and inspect the knife and plate for obstructions.
Maintenance
Proper maintenance extends the life and performance of your grinder knife.
- Cleaning: After each use, disassemble the grinder components. Wash the stainless steel grinder knife with warm, soapy water. The knife is dishwasher safe. Ensure all food particles are removed.
- Drying: Thoroughly dry the knife immediately after washing to prevent water spots and maintain its finish.
- Storage: Store the grinder knife in a dry place, ideally with other grinder components, to prevent loss or damage.
- Sharpening: While stainless steel knives retain sharpness longer, professional sharpening may be required over time for optimal performance. Consult a professional knife sharpener if the knife's cutting efficiency diminishes significantly.
Troubleshooting
If you encounter issues, review these common troubleshooting steps.
- Poor Grinding Performance:
- Issue: Meat is being mashed or smeared rather than cleanly cut.
- Solution: Ensure the grinder knife is installed with the cutting edge facing outwards, against the grinder plate. Verify the knife is sharp; if dull, consider professional sharpening or replacement. Ensure meat is properly chilled.
- Knife Not Fitting:
- Issue: The knife does not sit correctly on the auger shaft or with the plate.
- Solution: Confirm you have the correct size knife (#10/#12) for your grinder model. Check for any obstructions or damage to the auger shaft or knife opening.
- Grinder Jams Frequently:
- Issue: The grinder stops or slows down during operation.
- Solution: Turn off and unplug the grinder. Disassemble and clear any blockages. Ensure meat is cut into smaller pieces and is sufficiently chilled.
