4.1 Tool Body and Handle

The tool features a slim design with a soft rubber handle intended to provide a comfortable grip and reduce hand fatigue during use.

The tool is equipped with a 21V brushless motor, delivering a maximum torque of 74 Ft-lbs (100 N.m) for tackling stubborn fasteners.

4.3 Control Switches

• Forward/Reverse Switch: Located on the back of the tool head. This switch changes the rotation direction for tightening (forward) or loosening (reverse) bolts.
• Safety Lock Switch: Prevents the trigger from being pressed accidentally, helping to avoid unintentional operation.
• Trigger: A variable-speed trigger controls the tool's rotation speed. The harder you press, the faster it turns.

4.4 Built-in LED Light

A bright LED work light is integrated into the tool to illuminate dark, confined, or hard-to-reach work areas.

4.5 Battery and Charging System

• The kit includes two 21V, 2000mAh lithium-ion batteries.
• Batteries have a power level indicator.
• It is recommended to use the two batteries interchangeably: while one is in use, the other can be charging. This practice can help reduce wear on each battery.
• Use only the provided charger to recharge the batteries.

5. Use Guide

5.1 Before First Use

1. Fully charge both batteries using the provided charger.
2. Inspect the tool, battery, charger, and all accessories for any signs of damage.
3. Familiarize yourself with the location and function of all switches and indicators.

5.2 Installing and Removing the Battery

1. To install: Align the battery with the slot on the tool handle and slide it in until it clicks securely into place.
2. To remove: Press the battery release buttons on both sides of the battery and slide it out of the tool.

5.3 Selecting and Attaching Sockets/Attachments

1. Select the correct socket size for your fastener.
2. Push the socket, extension bar, or adapter onto the 3/8" square drive of the ratchet head until it locks into place with an audible click.
3. To remove an attachment, pull the locking collar on the ratchet head back and pull the attachment off.
4. Use the provided 3/8" to 1/2" or 1/4" adapters to utilize sockets with different drive sizes.
5. Use the 3-inch extension bar to reach fasteners in deeper recesses.

5.4 Operating the Tool

1. Ensure the Safety Lock switch is in the unlocked position.
2. Set the Forward/Reverse switch to the desired direction (forward for tightening, reverse for loosening).
3. Place the socket securely onto the fastener (bolt or nut).
4. Press the trigger to start the tool. Apply gradual pressure for control.
5. For final tightening or breaking loose very tight fasteners, you may need to finish by hand with a traditional ratchet or breaker bar.
6. Release the trigger to stop.
7. Engage the Safety Lock switch when the tool is not in use.
