3. Product Overview
The Protmex 3/8-inch Cordless Ratchet Wrench is designed for efficient and convenient fastening and unfastening tasks. It features a powerful motor and user-friendly design for various applications.

- Variable Speed Trigger: Offers a 0-400 RPM variable speed for precise control.
- Compact Design: Ultra-thin head design allows access to tight spaces.
- Ergonomic Grip: Insulated soft grip absorbs impact and reduces hand fatigue.
- Built-in LED Light: Illuminates the work area for improved visibility in dark environments.
- Battery Indicator: Displays the remaining battery charge.
- Forward/Reverse Switch: Easily change rotation direction for tightening or loosening.
4. Setup
- Charge the Battery: Before first use, fully charge both 21V 2.0Ah Lithium-Ion batteries using the provided fast charger. The battery indicator lights will show charging progress.
- Install Battery: Align the battery pack with the base of the ratchet wrench and slide it in until it clicks securely into place. Ensure the battery is fully seated.
- Attach Socket/Adapter: Select the appropriate socket size (10-17mm) or the 1/4-inch drive adapter. For hard-to-reach areas, attach the 3-inch extension rod first, then the desired socket or adapter. Push the socket/adapter firmly onto the 3/8-inch square chuck until it locks.
5. Operating Instructions
- Select Rotation Direction: Use the forward/reverse switch located near the ratchet head to select the desired rotation direction (clockwise for tightening, counter-clockwise for loosening).
- Activate Tool: Press the variable speed trigger to start the ratchet. The speed of rotation is controlled by how much pressure is applied to the trigger. The built-in LED light will illuminate the work area when the trigger is pressed.
- Tightening/Loosening: Apply the socket to the fastener and press the trigger. For final tightening or breaking loose very tight fasteners, the tool can also be used manually like a standard ratchet.
- Lock Button: Use the lock button to prevent accidental activation when not in use.
