Important Safety Information
WARNING: Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
- Work Area Safety: Keep work area clean and well lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
- Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
- Personal Safety: Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. Always wear eye protection. Use safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection for appropriate conditions.
- Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools.
- Battery Tool Use and Care: Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

Setup and Assembly
1. Charging the Battery
- Connect the 18V Lithium-Ion Charger to a standard electrical outlet.
- Slide the 1.5 Ah Battery onto the charger, ensuring it clicks into place.
- Allow the battery to charge fully. The charger's indicator light will signal when charging is complete (refer to charger manual for specific light patterns).
- Once charged, remove the battery from the charger.
2. Installing the Battery
- Align the battery pack with the base of the impact wrench.
- Slide the battery into the tool until it locks securely into place. Ensure it is firmly seated to prevent accidental dislodgement during operation.
3. Attaching Sockets

Operation
Powering On/Off and Direction Control
- To turn the tool on, depress the trigger switch. The tool speed increases with increased trigger pressure.
- To turn the tool off, release the trigger switch.
- The forward/reverse selector switch is located above the trigger. Push the switch to the left for forward rotation (tightening) and to the right for reverse rotation (loosening). Position the switch in the center for the trigger lock, which prevents accidental starting.
Selecting Operating Modes
The impact wrench features 4 distinct modes to optimize performance for various applications:
- Mode 1 (Low Speed): Provides lower torque and speed for delicate applications or when precise control is needed.
- Mode 2 (Medium Speed): Offers balanced torque and speed for general fastening tasks.
- Mode 3 (High Speed): Delivers maximum torque (up to 160 ft./lbs.) and speed (up to 2,900 RPM) for demanding applications and stubborn fasteners.
- Auto Mode: This unique mode is designed to prevent overtightening during fastening and uncontrolled removal during loosening. It automatically adjusts speed and impact rate based on resistance.
Use the mode selection button, typically located near the base of the handle or on the tool head, to cycle through the available modes. An indicator light or display will show the currently selected mode.
Maintenance
General Cleaning
- Always disconnect the battery pack before performing any cleaning or maintenance.
