Maintenance Tips
- Lubricate air motor daily with pneumatic tool oil to ensure smooth, long-lasting operation.
- Use clean, dry compressed air at recommended pressure to prevent internal wear and corrosion.
- Inspect cone/plug wheels before use and replace any cracked, worn, or unbalanced abrasives.
- Keep air inlet and exhaust ports clear of dust and grinding debris for proper airflow.
- Check spindle, collet, and wheel mounting for tightness and alignment before operation.
- Ensure hoses and fittings are leak-free to maintain consistent RPM and grinding power.
- Do not exceed rated wheel speed to prevent safety hazards and premature tool damage.
- Monitor vibration during use; excessive vibration may indicate imbalance or worn bearings.
- Clean tool housing after each use to remove metal dust and contaminants.
- Store in a dry, clean environment to protect internal components from moisture and corrosion.
