2. Safety Instructions
Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury. Read all instructions before operating this tool.
General Power Tool Safety:
- Work Area Safety: Keep work area clean and well lit. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.
- Electrical Safety: Avoid body contact with earthed or grounded surfaces. Do not expose power tools to rain or wet conditions.
- Personal Safety: Always wear eye protection (safety goggles), hearing protection, and appropriate respiratory protection. Use personal protective equipment such as non-skid safety shoes and a hard hat when necessary. Dress properly; do not wear loose clothing or jewelry.
- Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.
Angle Grinder Specific Safety:
- Guards: Always use the appropriate guard for the type of operation. Ensure the guard is securely attached and positioned for maximum safety.
- Discs: Use only discs that are rated for the maximum RPM of the grinder (12000 rpm). Inspect discs for damage before use.
- 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.
- Anti-Restart System: This grinder is equipped with an anti-restart system. If power is interrupted during operation, the tool will not restart automatically when power is restored. You must manually cycle the power switch to restart the tool.
- Ventilation: Do not block the ventilation openings. Keep them clean to prevent overheating.
3. Setup
3.1 Unpacking:
Carefully remove the angle grinder and all accessories from the carrying case. Inspect for any damage that may have occurred during shipping. Keep the packaging for future storage or transport.
3.2 Attaching the Side Handle:
The side handle can be screwed into one of three positions on the grinder head, depending on your preference and the application. Ensure it is tightened securely before use.
3.3 Installing/Changing Grinding Discs:
- Ensure the tool is unplugged from the power source.
- Press and hold the spindle lock button.
- Use the integrated wrench (located in the side handle) to loosen the outer flange nut by turning it counter-clockwise.
- Remove the outer flange nut and the old disc.
- Place the new disc onto the inner flange, ensuring it is seated correctly.
- Replace the outer flange nut and tighten it clockwise using the integrated wrench while holding the spindle lock button. Do not overtighten.
3.4 Adjusting the Guard:
The guard can be rotated to provide optimal protection for your specific cutting or grinding task. Loosen the guard clamp screw, rotate the guard to the desired position, and then securely tighten the clamp screw.
4. Operating
Before operating, ensure all safety precautions are followed and the correct disc and guard are installed for your task.
4.1 Powering On/Off:
- To turn on, slide the power switch forward.
- To turn off, slide the power switch backward.
4.2 Proper Grip and Posture:
Always hold the grinder firmly with both hands, one on the main handle and one on the side handle. Maintain a balanced stance and keep your body clear of the rotating disc's path.
4.3 Grinding and Cutting Techniques:
- Cutting: For cutting operations, use a thin cutting disc. Apply light, consistent pressure and allow the disc to do the work. Avoid twisting or binding the disc in the cut.

- Surface Grinding: For surface grinding, use a thicker grinding disc. Hold the grinder at a slight angle (typically 15-30 degrees) to the workpiece. Move the grinder smoothly across the surface, applying even pressure.

4.4 Material Considerations:
Always use the correct type of disc for the material you are working on (e.g., metal, stone, tile). Different materials require different disc compositions and techniques.
5. Maintenance
Regular maintenance ensures the longevity and safe operation of your angle grinder. Always unplug the tool before performing any maintenance.
- Cleaning: Regularly clean the tool's ventilation slots to prevent dust buildup, which can lead to overheating. Use a soft brush or compressed air. Wipe the exterior with a damp cloth. Do not use harsh chemicals.
- Carbon Brush Inspection/Replacement: The high-quality carbon brushes are designed for durability. If the tool experiences reduced power or intermittent operation, the carbon brushes may need inspection or replacement. Access ports are designed for easy maintenance. Refer to a qualified service technician if unsure.
- Disc Replacement: Replace worn or damaged discs immediately. Never use a disc that is cracked, chipped, or bent.
- Cord Inspection: Periodically inspect the power cord for any signs of damage, cuts, or fraying. If damaged, have it repaired by a qualified professional.
- Storage: Store the grinder in its original carrying case in a dry, secure place, out of reach of children.
