Specific Safety Precautions
⚠️ WARNING! DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to the tool safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.
⚠️ WARNING! Only use impact sockets with the impact wrench. Impact sockets have thicker walls and are made of ductile material to handle vibration. Regular drive sockets may rupture or explode under stress, injuring you or a bystander.
⚠️ WARNING! Immediately release the trigger if the tool's bit becomes stuck or jammed. The tool's torque can twist your arm and cause an injury. The tool may twist out of your grip and cause an injury to yourself or a bystander.
- Use the correct tool for the job. This tool was designed for a specific function. Do not modify or alter this tool or use it for an unintended purpose.
- A loose or mismatched bit may be ejected by the tool, causing an injury to the user or a bystander.
- Always hold the tool firmly in your hands before switching the tool ON. The reaction to the motor's torque may cause the tool to twist, as it accelerates to full speed.
- Never attempt to change the impact socket's direction of rotation while it is active. This can damage the interlock feature built into the switch. Be sure the impact socket has completely stopped and engage any safety features before changing the rotation direction. Turn the power off as an added precaution.
- Do not cool the impact socket with any liquid when hot. This can damage the the impact socket by weakening the material, making the accessory unsafe for use.
- Inspect the tool components periodically. Repair or replace damaged or worn components. Only use identical replacement parts when servicing.
Power Tool Precautions
- Do not use any power tool with a malfunctioning trigger, power switch or control. A power tool that fails to respond to the controls is dangerous and can cause an injury. A qualified technician must repair and verify the power tool is operating correctly, before it can be used.
- Shut the power off and disconnect the impact wrench from the power supply (if possible) before making any adjustments, changing accessories, cleaning, servicing or when storing. Such preventive safety measures reduce the risk of starting the tool accidentally.
- Check if the impact wrench's moving parts are misaligned or binding before each use. Correct the issue before using the impact wrench to avoid an injury or damage to the tool.
Kickback Precautions
Kickback is a sudden reaction when an impact socket is pinched or snagged on the material. If kickback occurs:
- The impact socket may contact a body part, causing a serious injury
- The impact wrench may wrench the user's arm causing muscle or joint injuries
- Kickback can also damage the tool or workpiece.
Kickback can be avoided by taking proper precautions:
- Only use an impact socket designed for the tool.
- Maintain control of a long workpiece or large panel by placing supports under the material on either side of the impact wrench.
- Always make sure the work surface is free from debris or other foreign objects. Striking debris can cause the impact wrench to jump and damage the impact socket.
Unpacking
⚠️ WARNING! Do not operate the tool if any part is missing. Replace the missing part before operating. Failure to do so could result in a malfunction and personal injury.
Remove the parts and accessories from the packaging and inspect for damage.

Operations
Socket Installation
? CAUTION! Make sure that the nut or bolt can withstand the rated torque and RPM (see Specifications). Consult the recommended torque specifications for the nut or bolt.
- Select the appropriately sized drive impact socket for the job. Only use impact sockets which are specifically designed for use with an impact wrench. Do not use worn or damaged sockets.
- Push and snap the socket onto the anvil.
- The extension bar increases the tool's reach for recessed nuts or bolts. Push the extension bar onto the anvil, then insert the socket into the other end.
- Make sure the extension bar is capable of withstanding the rotation forces without bending or breaking.
- Pull the socket off the anvil once the task is complete.
Drive Control
- Press the right-hand control button to increase the impact wrench's range of rotations and impacts per minute. An additional LED bar will glow with the increase of each level.
- The left-hand button controls the anvil function when using the impact wrench in reverse.
- a. Press the left-hand button to activate. The red LED will illuminate. When the impact wrench 'breaks' a fastener loose, the anvil will automatically stop. This function is best when you wish to loosen, but not remove a fastener.
- b. Press the left-hand button to deactivate. The red LED will shut off. When the impact wrench 'breaks' a fastener loose, the anvil will continue to turn until the trigger is released. This function is best when you wish to remove a fastener.
