General Safety Instructions
Always follow basic safety precautions when using power tools to reduce the risk of fire, electric shock, and personal injury.
- 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: Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
- Personal Safety: Always wear eye protection. Use appropriate personal protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection when necessary. Stay alert, watch what you are doing, and use common sense when operating a power tool.
- Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. It will do the job better and safer at the rate for which it was designed. Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.
- Battery Tool Use and Care: Recharge only with the charger specified by the manufacturer. Use power tools only with specifically designated battery packs.

Grinding and Cutting Techniques
- Always hold the grinder firmly with both hands.
- Allow the wheel to reach full speed before contacting the workpiece.
- Apply light, consistent pressure. Do not force the tool, as this can lead to kickback or damage.
- For grinding, maintain a small angle (typically 15-30 degrees) between the wheel and the workpiece.
- For cutting, use a cutting wheel and hold the tool perpendicular to the workpiece, making straight cuts.
- Ensure proper ventilation and clear the work area of bystanders.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your tool.
- Cleaning: Periodically blow dirt and dust out of the main housing with dry air. Do not use solvents or harsh chemicals.
- Inspection: Regularly inspect the wheel guard, side handle, and power cord (if applicable) for damage. Check grinding wheels for cracks or wear before each use.
- Brushless Motor: This tool features a brushless motor, which requires less maintenance compared to brushed motors as there are no carbon brushes to replace.
- Lubrication: This tool is factory lubricated and requires no additional lubrication.
