2. Important Safety Information
Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury when operating power tools. Keep this manual for future reference.
General Power Tool Safety Warnings
- Work Area Safety: Keep 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.
- Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. 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 hearing protection when operating the tool for extended periods. Dress properly. Do not wear loose clothing or jewelry. Keep your 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 plug from the power source before making any adjustments, changing accessories, or storing power tools.
- Specific Grinder Safety: Always use guards. Ensure the guard is securely attached and positioned for maximum safety. Use only accessories that are recommended by the manufacturer for your specific model.

3.2 Attaching the Anti-Vibration Side Handle
The anti-vibration side handle can be screwed into either side of the gear housing, depending on your preference and the application. This handle helps reduce vibration for increased user comfort and control.
- Identify the threaded holes on both sides of the grinder's gear housing.
- Screw the anti-vibration side handle firmly into the desired hole.

3.3 Installing the Guard
The angle grinder comes with an adjustable tool-free guard. This guard is essential for user safety during operation.
- Align the guard with the mounting collar on the grinder head.
- Press the guard onto the collar until it clicks into place.
- Rotate the guard to the desired position for your application. Ensure it provides maximum protection.
3.4 Installing Grinding/Cutting Discs
Always ensure the grinder is unplugged from the power source before changing discs. Use only discs appropriate for the tool's specifications and the material being worked on.
- Ensure the inner flange is correctly seated on the spindle.
- Place the grinding or cutting disc onto the spindle, ensuring it sits flush against the inner flange.
- Thread the outer lock nut onto the spindle and tighten it firmly using the provided lock nut wrench.
- Press the spindle lock button to prevent the spindle from rotating while tightening the nut.
4. Operating Instructions
4.1 Powering On/Off (Slide Switch)
The GWS14-60 features a convenient slide switch for easier long-run operation.
- To turn the tool ON, slide the switch forward until it locks into the ON position.
- To turn the tool OFF, slide the switch backward to the OFF position.
4.2 Variable-Speed Selection
The tool features variable-speed selection to match the speed to the specific application and material. The speed adjustment dial is located near the rear of the tool, potentially behind the air filter cover.
- Adjust the dial to select the desired RPM for your task. Lower speeds are suitable for polishing or delicate work, while higher speeds are for aggressive grinding and cutting.
4.3 Advanced Safety Features
- KickBack Control: This feature helps shut off the tool if the wheel gets into a binding situation, reducing the risk of sudden kickback.
- Restart Protection: Prevents accidental tool startup if the power supply is interrupted and then restored while the switch is in the ON position. The tool must be manually reset.
- Soft Start: Reduces the initial impact and torque for a smooth startup, enhancing user control and extending gear life.
- Overload Protection: Reduces the risk of the motor overloading or overheating during heavy-duty applications, protecting the tool from damage.
