General Safety Instructions
Always follow basic safety precautions when using electrical tools to reduce the risk of fire, electric shock, and personal injury. Familiarize yourself with all warnings and instructions.
Work Area Safety
- Keep the 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. Power tools create sparks which may ignite the dust or fumes.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical Safety
- Power tool plugs must match the outlet. Never modify the plug in any way.
- 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.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep cord away from heat, oil, sharp edges, or moving parts.
Personal Safety
- Always wear eye protection. Use safety glasses or goggles.
- Wear appropriate personal protective equipment (PPE) 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. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication.
- Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.
Specific Angle Grinder Safety
- Always use the protective guard. Ensure it is securely attached and positioned to provide maximum safety.
- Use only discs that are rated for the maximum speed of the grinder and are suitable for the material being worked on.
- Never use the grinder without the side handle securely attached. The side handle provides essential control.
- Ensure the workpiece is stable and securely clamped before grinding or cutting.
- Avoid starting the grinder with the disc in contact with the workpiece.
- Be aware of kickback. Kickback is a sudden reaction to a pinched or snagged rotating wheel. Always maintain a firm grip on the tool.
- Allow the disc to come to a complete stop before setting the tool down.

Operation
Starting and Stopping the Tool
- To Start: Ensure the tool is securely gripped with both hands. Plug the tool into a suitable power outlet. Press the ON/OFF switch.
- To Stop: Release the ON/OFF switch. Allow the disc to come to a complete stop before setting the tool down.
Grinding and Cutting Techniques
- Always hold the grinder firmly with both hands.
- For grinding, apply light, even pressure and move the tool smoothly across the workpiece. Avoid excessive pressure, which can damage the disc and motor.
- For cutting, ensure the cutting disc is suitable for the material. Make shallow passes, gradually increasing depth. Do not twist or force the disc, as this can cause kickback or disc breakage.
- Maintain a safe distance from the rotating disc and direct sparks away from yourself and others.
Workpiece Securing
Always secure your workpiece using clamps, a vise, or other appropriate methods. Never hold the workpiece by hand while operating the grinder, as this can lead to serious injury.
Maintenance
Regular maintenance ensures the longevity and safe operation of your angle grinder. Always unplug the tool before performing any maintenance.
Cleaning
- Keep the ventilation openings clean to prevent motor overheating. Use compressed air to blow out dust and debris from the tool's housing.
- Wipe the exterior of the tool with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
Carbon Brush Replacement
The DWE492-QS features a specific opening for quick carbon brush replacement. Worn carbon brushes can lead to reduced performance or tool failure. Refer to the service diagram (if available) or consult a qualified service technician for replacement. Ensure genuine DeWalt replacement brushes are used.
Disc Inspection
Before each use, inspect grinding and cutting discs for cracks, chips, or other damage. Never use a damaged disc, as it can shatter during operation and cause serious injury.
