3. Press Spindle Lock: Press and hold the spindle lock button to prevent the spindle from rotating.
4. Remove Outer Flange Nut: Use the provided spanner wrench to loosen and remove the outer flange nut.
5. Place Disc: Position the grinding disc onto the inner flange, ensuring it sits flat and centered. The disc should be rated for the grinder's speed and application.

5. Operating Instructions

Follow these steps for safe and effective operation of your Ingco Angle Grinder.

5.1 Before Starting

• Ensure all safety precautions are understood and followed.
• Wear all necessary PPE (safety glasses, hearing protection, gloves, dust mask).
• Secure the workpiece firmly to prevent movement during grinding.
• Inspect the grinding disc for any damage or cracks. Replace damaged discs immediately.
• Check that the power cord is in good condition and positioned to avoid accidental cutting.

5.2 Starting and Stopping the Grinder

1. Starting: With a firm two-handed grip on the main and auxiliary handles, plug the tool into a suitable power outlet. Press the power switch to the "ON" position. Allow the disc to reach full speed before contacting the workpiece.
2. Stopping: Release or press the power switch to the "OFF" position. Wait for the disc to come to a complete stop before setting the tool down.

5.3 Grinding Techniques

• Angle of Approach: For general grinding, hold the disc at an angle of approximately 15-30 degrees to the workpiece surface. For cutting, hold the disc perpendicular to the surface.
• Light Pressure: Allow the weight of the tool and the abrasive action of the disc to do the work. Excessive pressure can reduce efficiency, damage the disc, and overload the motor.
• Even Movement: Move the grinder smoothly and evenly across the workpiece to achieve a consistent finish and prevent gouging.
• Avoid Kickback: Be aware of potential kickback, especially when cutting. Avoid pinching the disc in the cut.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your angle grinder. Always disconnect the tool from the power supply before performing any maintenance.

6.1 Cleaning

• Regularly clean the ventilation slots to prevent overheating. Use compressed air to blow out dust and debris.
• Wipe the exterior of the tool with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Inspect the power cord for cuts, fraying, or damage. Replace if necessary.

6.2 Carbon Brush Replacement

The carbon brushes are wear items and will need replacement over time. Your grinder comes with a spare set of carbon brushes.

1. Unplug the tool from the power source.
2. Locate the brush caps on the sides of the motor housing.
3. Unscrew the brush caps using a screwdriver or coin.
4. Carefully remove the old carbon brushes.
