5. Setup

Before first use, ensure the wrench is ready for operation:

1. Battery Installation/Charging: If your model uses removable batteries, install them according to the polarity markings. If it has a rechargeable battery, connect the provided charger to the wrench and a suitable power outlet. Allow sufficient time for a full charge as indicated in the specific model's manual.
2. Power On: Press the power button (if available) or a designated button to turn on the digital display.
3. Unit Selection: Use the 'MD' (Mode) button to cycle through available torque units (e.g., N·m, kgf·m, lbf·ft, lbf·in) and select your desired unit.

6. Operating Instructions

Follow these steps for accurate torque application:

1. Attach Socket: Select the appropriate socket or attachment for your fastener and securely attach it to the ratchet head of the torque wrench.
2. Set Target Torque (if applicable): Some models allow pre-setting a target torque. Refer to your specific model's manual for instructions on how to adjust the target torque using the control buttons.
3. Apply Torque: Place the socket onto the fastener. Apply smooth, steady force to the wrench handle in the tightening direction. Observe the digital display for the real-time torque reading.
4. Read Torque: The digital display will show the applied torque. For models with peak hold, the maximum torque applied will be displayed after the force is removed.
5. Release Fastener: Once the desired torque is reached, release the pressure.
6. Power Off: Turn off the wrench after use to conserve battery life.

7. Maintenance

Proper maintenance ensures the longevity and accuracy of your torque wrench:

• Cleaning: Wipe the wrench clean with a soft, dry cloth after each use. Do not use harsh chemicals or solvents.
• Storage: Store the wrench in its original case or a protective container in a dry, temperature-controlled environment.
• Calibration: Digital torque wrenches require periodic calibration to maintain accuracy. Refer to your model's specific instructions for recommended calibration intervals and procedures, or contact an authorized service center.
