2. Battery Charging and Installation
- If the battery is not fully charged, connect it to the charger according to the charger's instructions. Allow the battery to charge completely before first use.
- To install the battery, slide it into the battery slot on the grinder until it clicks securely into place. Ensure it is firmly seated to prevent accidental dislodgement during operation.
- To remove the battery, press the release button (if present) and slide the battery out.
3. Attaching the Auxiliary Handle
The auxiliary handle can be screwed into one of the designated threaded holes on the gear head, depending on the desired working position and user preference. Ensure it is tightened securely.
4. Mounting the Protective Guard
Position the protective guard over the spindle collar. Rotate it to ensure it covers the grinding or cutting disc adequately and provides maximum protection. Secure it firmly using the locking mechanism.
5. Installing Grinding/Cutting Discs
- Ensure the grinder is switched off and the battery is removed.
- Place the backing flange onto the spindle.
- Position the desired grinding or cutting disc onto the backing flange, ensuring it sits flat.
- Screw the flange nut onto the spindle and tighten it firmly using the spanner wrench provided.
- Always use discs appropriate for the material and application.
Operating Instructions
1. Safety Precautions
Always wear appropriate personal protective equipment (PPE) including safety glasses, hearing protection, gloves, and a dust mask. Ensure your work area is clear of obstructions and well-ventilated. Never operate the grinder without the protective guard properly installed.
2. Powering On and Off
- To switch on: Slide the ON/OFF switch to the "ON" position.
- To switch off: Slide the ON/OFF switch to the "OFF" position.
- The grinder features restart protection, preventing it from automatically restarting after a power interruption if the switch is still in the "ON" position.
3. Speed Control
The intuitive 6-speed dial wheel allows you to adjust the rotational speed of the disc to match the material and application. Lower speeds are suitable for delicate work or softer materials, while higher speeds are for aggressive cutting or grinding on harder materials. Adjust the speed before starting the operation.
4. Grinding and Cutting Techniques
Hold the grinder firmly with both hands. Apply steady, even pressure. For cutting, allow the disc to do the work; do not force it. For grinding, move the grinder smoothly across the surface. Be aware of kickback control, which automatically shuts down the tool if it jams.

Maintenance
1. Cleaning
Regularly clean the ventilation slots of the grinder to prevent overheating. Use a soft brush or compressed air to remove dust and debris. Do not use water or solvents. Keep the handle and grip surfaces clean and dry.
2. Disc Replacement
Replace worn or damaged grinding/cutting discs immediately. Always ensure the replacement disc is compatible with the grinder's specifications (diameter, bore size, maximum RPM).
3. Storage
Store the angle grinder and its accessories in a dry, secure place, away from direct sunlight and extreme temperatures. Use the provided carrying case for protection during storage and transport.
4. Battery Care
Store batteries in a cool, dry place. Do not expose them to extreme heat or cold. For long-term storage, it is recommended to store batteries at a partial charge (e.g., 50%).
