Key Features

• High Efficiency Stepless Speed Control: Offers 300N·m torque and 0-2300rpm speed. The stepless speed control allows precise adjustment of rotation speed, making it suitable for both heavy-duty and delicate tasks.
• Quick Attachment & LED Light: Features a 1/2-inch drive square compatible with most standard sockets. The built-in LED light illuminates the work area for safe operation in dark environments.
• Forward/Reverse Rotation & Anti-Drop Mechanism: This electric impact wrench supports both forward and reverse rotation. In forward rotation, you can select between automatic stop mode and high-efficiency mode. The automatic stop mode is a key feature, preventing nuts from being lost due to excessive force when loosening them, which is beneficial for work efficiency. In reverse rotation, when tightening nuts, you can choose between power-saving mode (0-1900rpm min-1) and high-efficiency mode (0-2300rpm min-1), which helps prevent unnecessary power consumption.
• Durable Brushless Motor: The brushless motor eliminates carbon brushes, allowing the powerful BL motor to operate at lower temperatures and more efficiently. This also results in high durability and maintenance-free operation. KIMO's vibration control system maintains low levels of vibration and noise, providing a more comfortable and quieter working experience than many competitors.
• Cordless and Lightweight Design: This compact, cordless rechargeable impact wrench can be used anywhere after a full charge, offering convenient portability for various tasks. The soft-grip design ensures a secure, non-slip hold for comfortable use. It is easy for women and the elderly to use. It is also highly effective and safer for construction and maintenance work in high places or remote sites.

Setup

1. Charging the Battery

Before first use, fully charge the provided 2.0Ah Lithium-Ion battery. Connect the rapid charger to a power outlet and insert the battery. The charger's indicator lights will show the charging status. Ensure the battery is fully charged before operation to maximize performance and battery life.

2. Attaching the Socket

1. Ensure the impact wrench is turned off and the forward/reverse switch is in the neutral (locked) position.
2. Align the 1/2-inch socket with the drive square on the wrench.
3. Push the socket firmly onto the drive square until it clicks into place.
4. To remove the socket: Hold the socket with the upper half clamped in a vise (if available), support the wrench by hand, and gently tap the neck area of the wrench with a plastic hammer to dislodge the socket. If removal is difficult, apply a small amount of lubricant to the convex part where the socket fits.

Operating Instructions

1. Power On/Off and Speed Control

The tool is activated by pressing the trigger switch. The rotation speed is steplessly variable, meaning the more you press the trigger, the faster the tool operates (0-2300rpm). Release the trigger to turn off the tool.

2. Forward/Reverse Rotation

Use the forward/reverse switch located above the trigger to select the desired rotation direction. Push the switch to the left for forward rotation (tightening) and to the right for reverse rotation (loosening). Ensure the switch is in the center position for safety when not in use or when changing sockets.

3. Mode Selection (Forward Rotation)

In forward rotation, you can select between two modes:

• High-Efficiency Mode (0-1330rpm): For general tightening tasks requiring consistent power.
• Automatic Stop Mode: Designed to prevent over-tightening and loss of nuts. The tool automatically stops once the nut is sufficiently tightened.

4. Mode Selection (Reverse Rotation)

In reverse rotation (loosening), you can select between two speed ranges to optimize power consumption:

• Power-Saving Mode (0-1900rpm): For lighter loosening tasks, conserving battery life.
• High-Efficiency Mode (0-2300rpm): For stubborn nuts requiring maximum loosening power.

5. LED Work Light

The integrated LED light automatically illuminates the work area when the trigger is pressed, providing visibility in dimly lit spaces.

Maintenance

General Cleaning

Regularly clean the tool's exterior with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Keep ventilation openings clear of dust and debris to ensure proper cooling.

Socket Care

• Store sockets in a clean, dry place.
• After each use, remove the socket from the wrench and store it in the provided storage bag.
• If rust occurs on the socket or the drive square, apply a small amount of lubricant to the affected area and gently tap with a wrench or other tool to facilitate removal/attachment.

Battery Care and Storage

• To prolong battery life, always fully charge the battery after use before storing it.
• When storing the battery, keep it away from metal objects such as coins, keys, or nails, as these can cause short circuits and potential malfunctions.
• Store batteries in a cool, dry place, away from direct sunlight and extreme temperatures.
