Avhrit 1/2 Cordless Impact Wrench AH03 Instruction Manual

1. Safety Instructions

Always observe basic safety precautions when using electric tools to reduce the risk of fire, electric shock, and personal injury. Read all instructions before operating this tool.

1.1 General Power Tool Safety

• 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. Use personal protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection when appropriate. Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.

1.2 Battery 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 use battery packs other than those specifically designated for the power tool. Use of any other battery packs may create a risk of injury and fire.
• When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

5. Operating Instructions

5.1 Powering On/Off

To turn the tool on, press the trigger switch. To turn it off, release the trigger switch.

5.2 Adjusting Speed

The impact wrench features 3 variable speed settings, allowing you to adjust the speed based on the application. The speed is also variable by how much you depress the trigger.

• Speed Modes: The tool offers distinct speed modes (e.g., 0-1500 RPM, 0-1800 RPM, 0-2200 RPM) which can be selected via a mode button or switch.
• Variable Speed Trigger: The harder you press the trigger, the higher the speed, providing precise control.

5.3 Forward and Reverse Operation

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

• Forward (Tighten): Push the switch to the 'F' position for clockwise rotation.
• Reverse (Loosen): Push the switch to the 'R' position for counter-clockwise rotation.
• Lock Position: Center the switch to lock the trigger and prevent accidental operation.

5.4 Brake Stop Mode (Reverse)

In reverse mode, once a nut or bolt is loosened, the tool's brake function activates. This reduces speed and torque to prevent the fastener from flying off or getting stuck, enhancing safety and control.

5.5 Using the LED Work Light

The integrated LED light automatically illuminates when the trigger is pressed, providing visibility in dark or confined work areas.
