5. Operating Instructions
5.1 Powering On/Off

5.2 Mode Selection and Speed Adjustment
The CV350V2 offers both Auto Mode and Normal Mode (1-5 stages) for optimal performance across different tasks. The oscillation speed can be adjusted from 6,000 to 20,000 min-1.
- Normal Mode: Use the dial to select a speed setting from 1 to 5, corresponding to 6,000 to 20,000 oscillations per minute.
- Auto Mode: In Auto Mode, the tool automatically adjusts the oscillation speed based on the load, reducing noise and vibration during no-load operation and increasing speed when cutting. This allows for easier alignment of the blade at the start of a cut.
