Operating Instructions
1. Powering On/Off
To operate the tool, insert a charged battery pack. Press the trigger to activate the tool. Release the trigger to stop the tool.
2. Speed Control
The Avhrit AT700 offers four variable speed modes. Use the speed selector button to cycle through the modes:
- Mode 1: 0-1000 RPM (200 N.m) - Ideal for delicate tasks or starting screws.
- Mode 2: 0-1500 RPM (350 N.m) - Suitable for general screwdriving or light drilling.
- Mode 3: 0-2100 RPM (500 N.m) - For more demanding drilling or fastening.
- Mode 4: 0-2700 RPM (650 N.m) - High speed for removing stubborn nuts or heavy-duty applications.
The speed also varies with trigger pressure; the harder you push, the faster the tool operates within the selected mode.

3. Forward/Reverse and Brake Step Mode
The forward/reverse switch controls the rotation direction of the tool.
- Forward (F): Push the switch to the left for tightening fasteners.
- Reverse (R): Push the switch to the right for loosening fasteners.
- Lock Position: Move the switch to the middle position to lock the trigger, preventing accidental startup.
- Brake Step Mode (Reverse): When operating in reverse, the tool's brake activates as soon as the nut or screw is loosened. This reduces speed and torque, preventing the fastener from flying off and getting lost.
