This document is a user manual for the Milwaukee M12 FRAIWF38 and M12 FRAIWF12 impact wrenches.
Function Description
The Milwaukee M12 FRAIWF38 and M12 FRAIWF12 are cordless impact wrenches designed for fastening and unfastening applications. They are part of the Milwaukee M12 FUEL™ line, indicating they utilize advanced brushless motor technology for increased power, runtime, and durability. The tools feature a compact, right-angle design, making them suitable for working in confined spaces.
Key functions include:
- Fastening and Unfastening: The primary function is to drive and remove fasteners, such as nuts and bolts, with significant torque.
- Variable Speed Control: The tools offer multiple speed modes (1, 2, 3, and a reverse mode) to adapt to different applications and materials, providing precise control over the fastening process.
- Integrated LED Light: An LED light illuminates the work area, improving visibility in dimly lit conditions.
- Battery Fuel Gauge: A built-in indicator displays the remaining battery charge, allowing users to monitor battery status and plan for recharging.
- Directional Control: A forward/reverse lever allows for easy switching between tightening and loosening operations.
- Lock-out Function: The tool can be locked to prevent accidental startup, enhancing safety during transport or when not in use.

Usage Features
The manual highlights several usage features for safe and effective operation:
- Battery Pack Removal/Insertion: Always remove the battery pack before starting any work on the product to prevent accidental startup. The battery pack slides into the handle until it clicks into place.
- Battery Fuel Gauge Check: Pressing the battery fuel gauge button for 2 seconds activates the LED indicators, showing the remaining charge (100%, 75%, 50%, 25%).
- Accessory Insertion/Removal: Sockets or other accessories are inserted onto the square drive by pushing them firmly until they are seated. Removal involves pulling them off.
- Work Area Illumination: The integrated LED light activates when the trigger is pressed, illuminating the work area. Users are warned not to stare directly into the light beam.
- Starting and Stopping: The tool is started by pressing the trigger. The speed can be adjusted using the speed selector. To stop, release the trigger. The tool also features an insulated gripping surface for safe handling.
- Direction of Rotation (Forward/Reverse/Lock): A slide switch on the tool allows selection of forward (tightening), reverse (loosening), or a locked position (center) to prevent accidental operation.
- Speed Control (DRIVE CONTROL): The drive control button adjusts the rotation speed (RPM) for the application. The tool offers three distinct speed modes (1, 2, 3) and a reverse mode, each with specific RPM ranges and torque values, allowing users to match the tool's performance to the task requirements. The Auto Shut Off Mode (Q) automatically stops the tool once the torque is achieved in reverse, preventing over-tightening or damage.
Maintenance Features
The manual emphasizes several maintenance and safety aspects:
- General Safety Warnings: Users are instructed to read all safety warnings, instructions, illustrations, and specifications provided with the power tool to avoid electric shock, fire, and serious injury.
- Impact Wrench Safety Warnings: Hold the power tool by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring, as contact with a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock. Wear ear protectors. Exposure to noise can cause hearing loss.
- Additional Safety and Working Instructions:
- Use protective equipment: Always wear safety glasses when working with the product. Use protective clothing, such as dust mask, protective gloves, sturdy non-slip footwear, helmet, and ear defenders.
- Dust protection: The dust produced when using the product may be harmful to health. Do not inhale the dust. Wear a suitable dust protection mask.
- Avoid contact with hazardous materials: Do not use the product near any materials that present a danger to health.
- Tool insertion: Turn off the product immediately if the insertion tool stalls. Do not turn on the product again while the insertion tool is stalled, as doing so could trigger a sudden recoil with a high reactive force. Determine why the insertion tool stalled and rectify this, paying heed to the safety instructions.
- Possible causes for stalling: The insertion tool is tilted in the workpiece, the insertion tool has pierced through the material, or the product is overloaded.
- Do not reach into the product while it is running.
- The insertion tool may become hot during use.
- Warnings for improper use: Danger of burns when changing products, when setting the product down. Chips and splinters must not be removed while the product is running.
- Working on walls, ceiling, or floor: Take care to avoid electric cables and gas or water pipes.
- Clamping: Clamp your workpiece with a clamping device. Unclamped workpieces can cause severe injury and damage.
- Battery Pack Maintenance:
- Remove the battery pack before starting any work on the product.
- Do not dispose of used battery packs in the household refuse or by burning them. MILWAUKEE distributors offer to retrieve old batteries to protect the environment.
- Do not store the battery pack together with metal objects (short circuit risk).
- Use only M12 System chargers for charging M12 System battery packs. Do not use battery packs from other systems.
- Never break open battery packs and chargers, and store them only in dry rooms. Keep battery packs and chargers dry at all times.
- Battery acid may leak from damaged batteries under extreme load or extreme temperatures. In case of contact with battery acid, wash it off immediately with soap and water. In case of eye contact, rinse thoroughly for at least 10 minutes and immediately seek medical attention.

- Avoid exposing the battery pack to direct sunlight, heat, or fire.
- Do not short-circuit a battery pack.
- Do not store battery packs in a box or drawer where they may short-circuit each other or be short-circuited by conductive materials.
- Do not charge a battery pack in the rain or wet conditions.
- Use only chargers specified by the manufacturer.
- Do not use a battery pack or tool that is damaged or modified.
- Do not open battery packs.
- Do not crush, cut, or puncture battery packs.
- Do not expose battery packs to mechanical shock.
- In the event of a leak, do not allow the liquid to come into contact with the skin or eyes. If contact occurs, wash the affected area with water and seek medical advice.
- Do not use a battery pack that is damaged or modified.
- Do not use a battery pack that is not intended for use with the tool.
- Do not use a battery pack that has been dropped or subjected to impact.
- Do not use a battery pack that is not fully charged.
- Do not use a battery pack that is not properly stored.
- Do not use a battery pack that is not properly maintained.
