lithium brushless wrench large torque impact disassembly lithium wrench 锂电无刷扳手 大扭矩冲击拆装锂电扳手

1. Product Features

1. This lithium battery brushless wrench is equipped with a brushless high-magnetic motor, which avoids the wear and degradation caused by carbon brushes in traditional brushed motors, ensuring stable and powerful power output.
2. Configure the reverse stop function, which prevents bolts and nuts from falling off accidentally during operation, enhancing control during on-site work.
3. The device features a ultra-short body structure, along with laser engraving and ergonomic handles that provide sufficient grip friction, making it suitable for prolonged handling tasks.
4. Equipped with a 360° orbiting high-luminance shadowless lamp, it provides extensive lighting in poorly lit areas such as dim workshops, foundation pits, and under equipment, eliminating the need for additional lighting equipment.
5. The output shaft is a 1/2" square shaft, compatible with common sleeve components on the market, offering a wide range of options.
6. The wireless lithium battery design eliminates the need for power cables, allowing mobile bolt removal and installation operations in workshops, construction sites, and outdoor areas.

2. Product Advantages

1. Compared to conventional brushed impact wrenches, brushless motors reduce brush friction losses, lower heat generation during operation, extend the motor's lifespan, and offer better operating noise performance.
2. Reversing the self-stop mechanism, reversing the loosened bolts to a relaxed state automatically stops the impact, preventing nuts from flying out and getting lost, thereby reducing the loss of components.
3. The body is compact and short, allowing it to fit into narrow spaces such as gaps in the frame and inside equipment for assembly and disassembly operations, making it suitable for complex working conditions.
4. Dual-speed adjustment, with quick and slow gears that can be switched between, meeting the needs of fastening and removal under various operating conditions.
5. 1/2 inch square output shaft; it can be directly installed with any common sleeve on the market, offering strong versatility in accessories, and makes purchasing replacement parts simple and convenient.
6. Modular detachable lithium battery pack, supports alternate replacement of backup batteries, reduces downtime caused by waiting for charging, and enhances continuous operation efficiency.
7. The surrounding light source has a wide illumination range, and can provide lighting in multiple angles without any local shadow obstruction at the working points.

6. Usage Instructions

1. Battery installation: Push the fully charged lithium battery pack into the bottom slot of the device, hearing a click sound indicates the battery is securely locked; to remove it, hold the side clip and pull the battery downward.
2. Sleeve installation: Ensure the machine is powered off and stopped. Fully insert the compatible specification sleeve onto the 1/2 inch square output shaft. Verify that the locking pin is in place, and the sleeve is secure without any looseness.
3. Gear selection: Based on the operating conditions, turn the gear knob to select a fast or slow gear; for tightening bolts, use the appropriate low-speed gear first.
4. Turn control: Move the middle direction switch button. Pressing it to the left activates forward rotation by tightening the bolt; pressing it to the right disables reverse rotation by removing the bolt. Keeping the button in the middle activates the safety lock, preventing the trigger from being pressed to start.
5. Power-on procedure: After all settings are completed, pull the trigger; the trigger stroke can control the speed of rotation; the surrounding shadowless lights will turn on simultaneously. During reverse disassembly operations, the reverse stop function will halt the impact output once the bolts loosen.
6. Task completed: Release the trigger, wait for the output shaft to stop rotating completely, move the direction switch to the middle safety lock position, remove the sleeve; once done, remove the battery and store it separately.

7. Precautions

1. Wear safety goggles at all times during operations, as debris may be generated during impact tasks, and avoid any damage to the eyes caused by debris; it is recommended to wear anti-slip gloves; loose clothing and jewelry are prohibited to prevent getting caught in rotating parts.
2. Use sleeves that meet the specified specifications. Do not continue using them if there are cracks or defects, to prevent the sleeve from breaking and flying out.
3. Tool operating status: Do not touch the rotating output shaft or sleeve. It must be completely stopped before removing or installing the sleeve and adjusting the equipment.
4. Do not force operations on bolts that exceed the M14 specifications, as exceeding the equipment capacity will cause motor overload and damage.
5. Lithium batteries should be kept away from high-temperature sources and open flames. It is prohibited to puncture the battery pack; when not in use, remove the batteries and store them in a cool and dry place to prevent water ingress and moisture.
6. During prolonged continuous operation, the body shell becomes significantly hot. It is necessary to stop the machine and let it cool down to prevent the motor from overheating and being damaged.
7. Tools must not be used in humid or rainy conditions to prevent electric leakage risks.
8. The equipment must be placed in a location inaccessible to children, and children are not allowed to operate the machine.
9. If the sleeve does not engage properly or the device makes unusual noises, you must stop using it immediately. Only after identifying and fixing the issue can you continue with the operation.
