Thank you for choosing the Ingco CAGLI1151 20V Cordless Angle Grinder. This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your tool. Please read these instructions carefully before use and keep them for future reference. This tool is designed for grinding and cutting metal and stone materials without the use of water. Always ensure you understand all safety warnings and instructions before operating the tool.

2. Safety Instructions

Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury.

General Power Tool Safety

• Work Area Safety: Keep your 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.
• Electrical Safety: This is a cordless tool. Ensure the battery pack is compatible with the tool and charger. Do not expose battery-powered tools to rain or wet conditions.
• Personal Safety: Always wear eye protection (safety goggles) and hearing protection. Use a dust mask if operations create dust. Dress properly; avoid loose clothing or jewelry. Keep hair, clothing, and gloves away from moving parts.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.

Angle Grinder Specific Safety

• Guards: Always use the protective guard provided with the tool. Ensure it is securely fastened and positioned for maximum safety.
• Discs: Use only discs that are correctly sized (115mm diameter) and rated for the maximum speed of the grinder (8500 RPM). Ensure the disc is suitable for the material being worked on (e.g., cutting disc for cutting, grinding disc for grinding).
• Kickback: Be aware of kickback, which is a sudden reaction to a pinched or snagged rotating wheel. Always maintain a firm grip on the tool and position your body and arm to resist kickback forces.
• Workpiece: Secure the workpiece. A clamped workpiece is safer than holding it by hand.
• Starting the Tool: Ensure the disc is clear of the workpiece before starting the tool.

Battery Pack Safety

• Use only the charger specified by the manufacturer.
• Do not short-circuit a battery pack or charger.
• Do not open or damage the battery pack.
• Do not store the tool or battery pack in locations where the temperature may reach or exceed 50°C (122°F).

2. Stopping: Release the power switch to the OFF position. Wait for the disc to come to a complete stop before setting the tool down.

5.2 Grinding and Cutting Techniques

• Grip: Always hold the angle grinder firmly with both hands, one on the main handle and one on the auxiliary handle.
• Angle: For grinding, hold the disc at a slight angle (typically 15-30 degrees) to the workpiece. For cutting, hold the disc perpendicular (90 degrees) to the workpiece.
• Pressure: Apply moderate, consistent pressure. Do not force the tool, as this can lead to overheating, reduced performance, and potential kickback. Let the tool do the work.
• Direction: Always direct sparks away from yourself and others.
• Cutting Performance: With a 2 Ah battery, you can cut approximately 6 bars of 16 mm steel. With a 4 Ah battery, you can cut approximately 18 bars of 16 mm steel.
• Runtime: A 2 Ah battery provides approximately 35 minutes of runtime, while a 4 Ah battery provides approximately 75 minutes. Actual runtime may vary based on load and material.
