Operating Instructions

1. Powering On/Off:

   To start the grinder, slide the lock-off button (if present) and then depress the trigger switch. To stop, release the trigger switch. Some models may have a slide switch that locks on for continuous operation; push it forward to engage and press the rear to release.

2. Grinding/Cutting Technique:

   Hold the tool firmly with both hands, ensuring a stable stance. Position the wheel at a slight angle to the workpiece for grinding, or perpendicular for cutting. Apply light, consistent pressure. Allow the tool's speed and power to do the work. Avoid excessive pressure, which can cause kickback or damage the wheel.

3. Automatic Speed Change Technology (ASC):

   The XAG04Z features ASC, which automatically adjusts the motor speed and torque during operation based on the load. This ensures optimal performance and efficiency for various applications without manual adjustment.

4. Active Feedback-sensing Technology (AFT):

   This safety feature automatically shuts off the motor if the rotation of the wheel is suddenly forced to stop, such as during a bind-up. This helps protect the user from kickback.
