1.1 Battery Charging
- Connect the charger to a standard 120-volt AC power outlet.
- Slide the 18V Lithium-Ion battery onto the charger until it clicks into place.
- The charger's indicator light will show the charging status. Refer to the charger's specific instructions for light patterns (e.g., solid red for charging, solid green for fully charged).
- Allow the battery to fully charge before first use. A full charge typically takes approximately one hour.
1.2 Battery Installation and Removal
- To install the battery, align the battery with the base of the impact driver and slide it in until it clicks securely into place.
- To remove the battery, press the release button(s) on the sides of the battery pack and slide the battery out of the tool.
1.3 Bit Installation
- Ensure the tool is off and the battery is removed before installing or removing bits.
- Pull the 1/4-inch hex chuck collar forward to open the chuck.
- Insert the hex shank bit fully into the chuck.
- Release the chuck collar. The bit should be held firmly in place. Pull on the bit to ensure it is securely seated.

2. Operating Instructions
This section details the proper use of your Bosch Impact Driver for various applications.
2.1 Powering On/Off and Variable Speed Control
- To turn the tool on, press the trigger switch. The speed of the tool is controlled by how far the trigger is depressed; pressing it further increases the speed.
- To turn the tool off, release the trigger switch.
- The variable speed trigger allows you to match the speed to the specific task, providing greater control for delicate applications or maximum power for heavy-duty fastening.
2.2 Forward/Reverse Rotation
- A forward/reverse selector switch is located above the trigger. Push the switch to the left for forward rotation (for driving screws) and to the right for reverse rotation (for removing screws).
- When the switch is in the center position, the trigger is locked, preventing accidental activation. Always engage the lock when the tool is not in use or when changing bits.
2.3 Impact Mechanism
The impact driver utilizes a hammer and anvil mechanism to deliver powerful rotational impacts, making it highly effective for driving long screws or lag bolts into dense materials. The impact action engages automatically when resistance is met.

3. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Bosch Impact Driver.
3.1 Battery Care
- Always store batteries in a cool, dry place away from direct sunlight and extreme temperatures.
- Do not allow batteries to fully discharge before recharging. The Electronic Cell Protection (ECP) system helps prevent deep discharging, but regular charging is recommended.
- Avoid exposing batteries to moisture or corrosive substances.
3.2 Cleaning
- Periodically clean the ventilation openings on the tool and charger to prevent overheating. Use a soft brush or compressed air.
