2. Safety Information

Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury. Failure to follow these warnings may result in serious injury or property damage.

General Power Tool Safety Warnings:

• Work Area Safety: Keep your 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.
• Electrical Safety: Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Personal Safety: Always wear eye protection (safety glasses or goggles) and hearing protection. Use appropriate personal protective equipment (PPE) such as non-skid safety shoes, hard hat, or hearing protection when necessary.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. It will do the job better and safer at the rate for which it was designed. Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.

Battery Pack Safety:

• Only use 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.
• Do not short-circuit a battery pack. Do not store battery packs indiscriminately in a box or drawer where they may short-circuit each other or be short-circuited by conductive materials.
• Do not expose battery packs to heat or fire. Avoid storage in direct sunlight.
• Do not use a battery pack or appliance that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.

5. Setup

5.1. Charging the Battery

Before first use, fully charge both 4.0Ah Lithium-Ion battery packs. The charger is designed for quick charging, typically taking 1 to 2 hours for a full charge.

1. Connect the fast charger to a standard power outlet.
2. Slide the battery pack onto the charger until it clicks into place.
3. The charger's indicator light will show the charging status (refer to charger manual for specific light patterns).
4. Once fully charged, remove the battery pack from the charger.

5.2. Installing and Removing the Battery Pack

• Installation: Align the battery pack with the receptacle on the bottom of the impact wrench. Slide the battery pack into place until it locks securely with a click.
• Removal: Press the battery pack release button (located on the front of the battery) and slide the battery pack out of the tool.

5.3. Attaching and Removing Sockets

• Attaching: Push the desired impact socket (17mm, 19mm, 21mm, or 24mm) onto the 1/2" square drive anvil of the impact wrench until it is firmly seated. Ensure the pin and rubber ring are used to secure the socket if applicable.
• Removing: Pull the socket firmly off the square drive anvil.

6. Operating Instructions

6.1. Powering On/Off and Variable Speed Control

The tool is activated by pressing the trigger switch. The speed of the tool is controlled by the amount of pressure applied to the trigger. Pressing the trigger further increases the speed.

6.2. Adjusting Speed Modes (RPM)

Your impact wrench features three distinct speed modes to match the requirements of your task:

• L (Low Speed): 0-2500 RPM - Ideal for delicate tasks or when precise control is needed.
• M (Medium Speed): 0-2900 RPM - Suitable for general fastening and loosening.
• H (High Speed): 0-3500 RPM - For maximum power and speed, such as removing stubborn bolts.

Use the speed mode selector button on the tool's control panel to cycle through these modes. The selected mode will be indicated on the smart control panel.

6.3. Using Forward and Reverse Modes

The forward/reverse switch allows you to change the direction of rotation for tightening or loosening fasteners.

• Forward Rotation (Tighten): Push the switch to the left (when viewed from the rear of the tool).
• Reverse Rotation (Loosen): Push the switch to the right.
• Locking Protection: Position the switch in the center to lock the trigger and prevent accidental operation.

6.4. Brake Stop Function (Reverse Mode Only)

When operating in reverse mode, the tool features a brake stop device. Once the nut or bolt is sufficiently loose, the tool will automatically reduce its speed and torque. This prevents the fastener from flying off and helps you catch it easily.

6.5. Built-in LED Work Light

The integrated LED light automatically illuminates when the trigger is pressed, providing visibility in dimly lit work areas. This feature is particularly useful for working in tight or dark spaces, ensuring accuracy.
