5.1 Powering On/Off and Speed Adjustment
- To turn the tool ON, slide the power switch forward.
- To turn the tool OFF, slide the power switch backward.
- This grinder features two-speed regulation: 3000 RPM and 8500 RPM. Use the speed selector switch to choose the appropriate speed for your task. Lower speeds are generally for polishing or lighter tasks, while higher speeds are for cutting and heavy grinding.
- The tool also includes an automatic lock function for continuous operation. Refer to the tool's body for the specific mechanism to engage and disengage this function.
5.2 Grinding and Cutting Techniques
Always hold the grinder firmly with both hands using the main handle and the auxiliary handle. Apply light, even pressure. Let the tool do the work.
- Grinding: Hold the grinder at a 15-30 degree angle to the workpiece. Move the tool back and forth evenly across the surface.
- Cutting: Hold the grinder perpendicular (90 degrees) to the workpiece. Make shallow passes, allowing the disc to cut through the material gradually. Do not twist or bind the disc in the cut.
