Maintenance Tips    

• Use clean, dry compressed air: Moisture or debris in the air supply quickly wears the vane motor and reduces power stability.
• Lubricate daily: Add a few drops of pneumatic tool oil before each use to keep internal vanes running smoothly and prevent premature wear.
• Maintain correct air pressure (≈90 PSI): Over-pressurizing increases RPM beyond safe limits and shortens tool and wheel life.
• Match accessory RPM rating: Only use cone or plug wheels rated for ≥20,000 RPM to avoid catastrophic wheel failure.
• Inspect wheels before every use: Never use cracked, chipped, or dropped abrasive cones/plugs—high-speed failure risk is severe.
• Keep spindle and adapter clean: Debris on the 3/8"-24 spindle or mounting surface causes vibration and uneven wear.
• Check for vibration at startup: Run briefly at low throttle after mounting a wheel—stop immediately if imbalance is detected.
• Keep rear exhaust clear: Ensures proper airflow and prevents heat buildup in the motor.
• Inspect hoses and fittings regularly: Air leaks reduce performance and can cause inconsistent RPM under load.
• Store dry and protected: Prevent corrosion inside the air motor and protect accessories from moisture and impact damage.
