2. Safety Instructions
Always observe general power tool safety warnings and specific instructions for angle grinders. Failure to follow these warnings and instructions may result in electric shock, fire, and/or serious injury.
General Safety
- Always wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, gloves, and a dust mask.
- Ensure the workpiece is securely clamped before operation.
- Keep hands clear of rotating parts and the cutting/grinding area.
- Do not operate the tool in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Keep children and bystanders away while operating a power tool.
Electrical Safety
- Ensure the power supply voltage matches the rating on the tool's nameplate.
- 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.
- If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply.
Specific Angle Grinder Safety
- Always use the protective guard. Ensure it is correctly positioned and securely fastened.
- Use only discs that are rated for the maximum speed of the grinder and are suitable for the material being worked on.
- Never use cutting discs for side grinding.
- Be aware of the anti-kickback feature; if the disc jams, the motor will shut off. Release the switch and clear the obstruction before restarting.
- Allow the disc to come to a complete stop using the mechanical brake before setting the tool down.

4. Setup
Attaching the SoftVib Handle
The SoftVib handle can be screwed into either the left or right side of the gearbox housing, depending on user preference and application. Ensure it is tightened securely.
Mounting the Protective Guard
The protective guard is tool-free adjustable. Position it to provide maximum protection for your specific task. Ensure it clicks securely into place.
Installing the Grinding/Cutting Disc
- Unplug the tool from the power supply.
- Press and hold the spindle lock button.
- Place the inner clamping flange onto the spindle.
- Place the desired 125mm disc onto the inner flange, ensuring it sits flush.
- Screw on the clamping nut (M14) and tighten it firmly using the integrated wrench in the SoftVib handle.
- Release the spindle lock button.
5. Operating Instructions
Powering On/Off
- To switch on, push the slide switch forward. For continuous operation, push it further forward until it locks into place.
- To switch off, release the slide switch. If locked, press the rear part of the switch to release it.
Variable Speed Control
The speed selection dial (Figure 2) allows you to adjust the no-load speed between 2800 and 11500 rpm. Select the appropriate speed for the material and application. Lower speeds are generally used for polishing or working with sensitive materials, while higher speeds are for cutting and grinding.
Using the Mechanical Brake
The integrated mechanical brake stops the disc within 3.5 seconds after the tool is switched off. This enhances safety by quickly stopping rotation.
Working with the Grinder
- Always hold the grinder firmly with both hands.
- Allow the tool to reach full operating speed before contacting the workpiece.
- Apply steady, even pressure. Do not force the tool, as this can lead to overheating or disc damage.
- For cutting, use a slight rocking motion to prevent the disc from binding.
- Be mindful of sparks and debris. Direct them away from yourself and others.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your Flex angle grinder.
Cleaning
- Always unplug the tool before cleaning.
- Regularly clean the ventilation slots to prevent dust buildup, which can lead to overheating. Use compressed air if available.
- Wipe the exterior of the tool with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
Carbon Brushes
The optimized carbon geometry contributes to long brush life. If the tool's performance significantly drops or sparks excessively, the carbon brushes may need inspection or replacement. This should ideally be done by a qualified service technician.
Storage
Store the angle grinder in a dry, secure place, out of reach of children and unauthorized users.
7. Troubleshooting
