5. Operating Instructions

5.1 Powering On/Off

The tool is activated by pressing the variable speed trigger. Release the trigger to turn off the tool.

5.2 Selecting Speed Modes

The Protmex C06302 features three speed modes (Low, Medium, High) to match different application requirements. Use the mode switch button, typically located near the handle, to cycle through the speeds. The current speed setting will be indicated on the tool's display.

5.4 Using the Two-way Brake Stop

When operating in reverse mode, the tool is equipped with a two-way brake stop function. Once a nut or bolt begins to loosen, the tool will automatically reduce its speed and torque. This feature helps prevent the fastener from completely detaching and falling, making it easier to retrieve.
