Operating Instructions
1. Power On/Off and Variable Speed Trigger
To operate the wrench, insert a charged battery and press the variable-speed trigger. The speed of the wrench is controlled by how much you depress the trigger. A locking switch prevents accidental activation during transport.
2. Speed Modes
The SEESII impact wrench offers 3 optimized gear settings for various tasks:
- 1st Gear (Low): 0-1400 RPM / 1900 IPM - Ideal for delicate work and precise applications.
- 2nd Gear (Medium): 0-1900 RPM / 2500 IPM - Suitable for standard bolts and general tasks.
- 3rd Gear (High): 0-2400 RPM / 2900 IPM - For stubborn nuts and heavy-duty applications.
Use the mode selection button to cycle through the speed settings.

3. Forward/Reverse Control
A one-touch switch allows you to easily change the rotation direction for tightening or loosening fasteners. Ensure the switch is in the desired position before operating.
4. Auto-Stop Function
The auto-stop feature is designed to prevent over-tightening damage. In reverse mode, it helps prevent nuts or bolts from being flung out by automatically stopping rotation once the fastener is loose.
