The Fellowes C-420C shredder is designed for smooth and efficient operation. However, users may occasionally encounter unusual noises like grinding or squeaking, which can indicate potential issues. These noises are often caused by lack of lubrication, misaligned parts, or wear and tear.
Addressing these problems promptly not only ensures quieter operation but also extends the life of your shredder. This guide will help you identify the causes and provide step-by-step solutions to fix noise-related issues.
Why Fixing Noise Issues is Important
Unusual noises in a shredder should never be ignored, as they often signal underlying mechanical problems. Here’s why resolving these issues is crucial:
- Prevents Further Damage: Ignoring noises can lead to wear on internal components, potentially requiring expensive repairs or replacements.
- Enhances Longevity: Regular maintenance, such as fixing noise issues, keeps the shredder in top condition for years.
- Improves User Experience: A quiet shredder ensures a more comfortable work environment, free from distracting or irritating sounds.

Common Causes of Fellowes C-420C Shredder Noise Issues
Shredder noise can be indicative of wear and tear, improper maintenance, or operational issues. Below are explanations of the most common causes of noise issues in the Fellowes C-420C shredder:
1. Dry or Unlubricated Blades
- Cause: Friction between the cutting blades increases when they lack lubrication, leading to grinding or squeaking sounds.
- Impact: Continuous operation without lubrication can cause permanent damage to the blades and motor.
- Prevention: Regularly apply Fellowes-approved shredder oil to the blades, following the recommended schedule of every 500 sheets or after emptying the bin.
2. Misaligned Components
- Cause: Blades, gears, or internal components may shift out of alignment due to frequent use or impacts during transportation.
- Impact: Misalignment creates resistance, leading to grinding noises and uneven shredding.
- Prevention: Perform regular checks and adjustments using the shredder’s manual as a guide to maintain proper alignment.
3. Loose Screws or Parts
- Cause: Vibrations during shredding can loosen screws or other fasteners over time, creating a rattling or clanking noise.
- Impact: Loose components can cause further damage to the internal structure if not tightened promptly.
- Prevention: Inspect and tighten screws and other parts during routine maintenance to avoid unnecessary noise.
4. Paper Dust and Debris Build-Up
- Cause: Accumulated paper dust and fragments can obstruct the cutting mechanism and gears, increasing strain and noise levels.
- Impact: If left uncleaned, debris can jam moving parts and reduce the machine’s efficiency.
- Prevention: Clean the shredder regularly with compressed air and a soft brush to ensure smooth operation.
5. Worn or Damaged Blades
- Cause: Continuous use, shredding thick materials, or mishandling can dull or damage the blades, resulting in grinding sounds.
- Impact: Dull blades reduce shredding performance and strain the motor.
- Prevention: Replace worn blades promptly to maintain efficient operation and avoid excessive noise.
Step-by-Step Guide to Fixing Noise Issues
Follow these steps to identify and resolve noise issues in your Fellowes C-420C shredder:
Step 1: Turn Off and Unplug the Shredder
Unplugging the machine ensures safety while you inspect and repair the shredder.
How to Do It:
Switch off the shredder and disconnect it from the power source before proceeding with maintenance.
Step 2: Inspect for Loose Parts
Loose screws or components can produce rattling or clanking noises during operation.
How to Do It:
- Open the shredder’s housing, following instructions in the manual.
- Check for loose screws or components and tighten them using a screwdriver.
Step 3: Lubricate the Blades
Proper lubrication reduces friction and prevents grinding or squeaking sounds.
How to Do It:
- Apply Fellowes-approved shredder oil in a zigzag pattern across the paper entry slot.
- Run the shredder in reverse mode for 10-15 seconds to distribute the oil evenly across the blades.
Step 4: Clean the Cutting Mechanism
Paper dust and debris can obstruct the blades and gears, leading to noisy operation.
How to Do It:
- Use compressed air to blow away loose particles from the cutting mechanism.
- Remove any lodged paper fragments with tweezers or a soft brush.
- Wipe down accessible areas with a dry, lint-free cloth.
Step 5: Realign Misaligned Components
Misalignment causes uneven shredding and grinding noises.
How to Do It:
- Inspect the position of the blades and gears for any visible misalignment.
- Use the manual to guide you in adjusting or repositioning the components.
Step 6: Test the Shredder
Testing ensures that the noise issues have been resolved and that the shredder operates smoothly.
How to Do It:
- Plug in the shredder and run a single sheet of paper through it.
- Gradually increase the paper load to confirm normal operation without noise.
Step 7: Replace Worn Components if Necessary
Worn blades or damaged gears can continue to produce noise even after cleaning and alignment.
How to Do It:
- Order replacement parts directly from Fellowes or authorized retailers.
- Follow the manual for proper installation of new components.
