Maintenance Tips

• Clean After Each Use: Wipe down the grinder to remove dust, debris, and residue. Use compressed air to clean internal components.
• Lubricate Regularly: Apply pneumatic tool oil to the air inlet before and after use to keep internal parts running smoothly.
• Inspect the Grinding Disc: Check for cracks, uneven wear, or dullness. Replace if damaged to ensure safe and effective grinding.
• Check Air Supply: Ensure the compressor provides the correct PSI and CFM for optimal performance. Drain moisture from the air lines regularly.
• Secure Fasteners: Periodically tighten screws, bolts, and disc attachments to prevent loosening during operation.
• Monitor Air Hoses: Inspect hoses for leaks, cracks, or kinks. Replace any damaged hoses to maintain steady airflow.
• Use Proper Grinding Pressure: Let the tool do the work—excessive force can cause overheating and premature wear.
