1. Introduction
Thank you for choosing the EBERTH IW5PN Pneumatic Sheet Metal Nibbler. This tool is designed for efficient and precise cutting of various sheet materials. To ensure safe operation and optimal performance, please read this manual thoroughly before use and keep it for future reference.
The EBERTH IW5PN is an air-powered tool, ideal for punching and cutting sheet steel up to 1.5 mm, aluminum up to 1.6 mm, and plastic up to 2.2 mm thickness. Its design allows for cutting not only flat sheets but also curved materials with ease.
2. Safety Instructions
Always observe general safety regulations for pneumatic tools to prevent injury and damage.
2.1 Personal Protective Equipment (PPE)
- Always wear safety glasses or a face shield to protect against flying debris.
- Wear hearing protection to prevent noise-induced hearing loss.
- Use work gloves to protect hands from sharp edges and vibrations.
- Wear appropriate work clothing; avoid loose clothing or jewelry that could get caught in moving parts.
2.2 Work Area Safety
- Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2.3 Tool Handling and Maintenance
- Ensure the tool is disconnected from the air supply before making any adjustments, changing accessories, or storing the tool.
- Maintain tools in perfect condition. A sharp blade provides good cutting results and safe working conditions.
- Do not overreach. Keep proper footing and balance at all times.
- Never point the tool at yourself or others.
3. Product Overview

4. Setup
4.1 Connecting to Air Supply
- Ensure your air compressor can provide sufficient compressed air. Pneumatic tools require adequate air pressure to operate at full power.
- Apply PTFE tape (Teflon tape) to the threads of the air fitting to ensure an airtight seal.
- Screw the quick-connect air fitting onto the tool's air inlet.
- Connect the air hose from your compressor to the quick-connect fitting on the tool.

4.2 Blade Installation/Check
The nibbler comes with a pre-installed blade. If you need to replace it, ensure the replacement blade (e.g., for EBERTH IW8-PN or compatible models) is correctly screwed into the metal nibbler with its guide. Always use a sharp, hardened steel blade for optimal performance and safety.
5. Operation
5.1 Material Compatibility
- Sheet Steel: Up to 1.5 mm thickness
- Aluminum: Up to 1.6 mm thickness
- Plastic: Up to 2.2 mm thickness
5.2 Cutting Techniques
- Starting a Cut: Place the nibbler head on the edge of the material or drill a pilot hole for internal cuts.
- Activating the Tool: Press the trigger to start the cutting action.
- Cutting Motion: Guide the nibbler steadily along your desired cutting line. Maintain a consistent feed rate.
- Curved Cuts: The nibbler is designed to handle curved cuts effectively. Apply steady pressure and guide the tool smoothly.
- Flat Sheet Cuts: For straight or flat cuts, ensure the material is securely clamped and guide the tool along a straight edge or marked line.

5.3 Important Notes
- Always ensure sufficient compressed air supply at the tool for optimal performance.
- Do not force the tool; let the nibbler do the work.
- Keep hands and fingers away from the cutting area during operation.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your EBERTH IW5PN Nibbler.
6.1 Daily Lubrication
Pneumatic tools require daily lubrication. Add a few drops of pneumatic tool oil into the air inlet before and after each use. The tool housing may indicate "OIL DAILY" as a reminder.

6.2 Cleaning
- After each use, disconnect the tool from the air supply.
- Clean the nibbler head and cutting area of any metal chips or debris using a brush or compressed air.
- Wipe down the tool body with a clean cloth.
6.3 Blade Replacement
A sharp blade is crucial for good cutting results and safe operation. Replace the blade when it becomes dull or damaged. Replacement blades are available for EBERTH pneumatic nibblers.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Low cutting performance / Slow operation | Insufficient air pressure or volume Dull or damaged blade Lack of lubrication | Check air compressor and hose for adequate supply Replace the blade Add pneumatic tool oil to the air inlet |
| Tool not starting | No air supply Trigger mechanism jammed | Ensure air hose is connected and compressor is on Check for obstructions around the trigger; ensure it moves freely |
| Excessive vibration or noise | Loose components Worn blade or internal parts | Inspect the tool for any loose screws or parts and tighten them Replace the blade; if problem persists, contact service |
