4. Operating Instructions
Powering On and Off:
Connect the angle grinder to a 120-volt power outlet. To start the tool, depress the locking trigger. For continuous operation, engage the lock-on switch. To turn off, release the trigger or disengage the lock-on switch. The soft start feature ensures a smooth power-up, reducing sudden jolts.
Grinding Techniques:
Hold the grinder firmly with both hands, utilizing the side handle for maximum control. Apply light, even pressure to the workpiece. Allow the tool's speed stabilization electronics to maintain consistent RPMs under load. Avoid excessive pressure, which can lead to overheating or premature disc wear. The Anti-Vibration technology helps reduce user fatigue during extended use.
