Frequently Asked Questions (FAQ)

Is an impact wrench suitable for changing car wheels?
Yes. The powerful 1000 Nm torque and 1/2" drive enable fast and reliable loosening and tightening of all types of car wheel bolts and nuts.
How many batteries are included in the kit?
The kit includes two (2) 21V 3.0Ah lithium-ion batteries. This allows you to work continuously, as you can charge one battery while using the other.
What is the purpose of the automatic shutdown function (AUTO STOP)?
The AUTO STOP function is designed for safe unscrewing. When the tool detects that the nut is loose, it automatically stops operation, preventing the nut from falling out or damaging the thread.

Instructions for using the product:
• Charging the battery before first use: Before starting work, insert one of the included 21V 3Ah lithium-ion batteries into the appropriate charger and charge it to 100% to reach full cell capacity.
• Battery installation: Push the charged battery into the lower part of the screwdriver handle until you hear a click, confirming correct and secure locking.
• Socket Wrench Installation: Firmly install the appropriate impact socket (nut) onto the 1/2-inch (1/2″) square drive of the chuck. For safety and to prevent kickback, always use the dedicated locking pin or ring if supported by the impact chuck.
• Mode selection and torque settings: Use the electronic switch on the housing to select the desired speed or power level depending on the complexity of the screwing or unscrewing task (e.g. tightening screws on car wheels or heavy construction work).
• Maintenance and storage: After finishing work, clean the tool housing, remove the battery and store the screwdriver and all accessories (batteries, charger, bits) in the included durable transport case.

Useful tips:
• Use of appropriate impact sockets: When working with a screwdriver that develops an incredible 1000 Nm of torque, use exclusively black, forged impact sockets (cr-mo steel), as ordinary hand-operated chrome-plated sockets can break under the impact force.
• Using two batteries in practice: The kit contains two 3Ah batteries. When one is running low, the other should be charged in the charger, ensuring uninterrupted work in the field or in the workshop without waiting.
• Optimal loosening of stubborn screws: When loosening heavily seized or rusted screws (e.g. car rims), turn on the highest impact level and hold the tool firmly with both hands in the axis of the screw to prevent slipping and damaging the screw head.
• LED work light efficiency: The built-in LED on the bottom of the handle automatically illuminates dark work areas under a car or in the corners of cabinets, so an additional light is often not needed.
• Regular maintenance of the brushless motor: Brushless technology does not require replacing carbon brushes, which reduces wear; just make sure the motor's ventilation slots are clean and unblocked.

Warnings:
• Use of personal protective equipment: When working with high-performance impact wrenches, always wear safety glasses (to protect against rust or metal chips) and ear protection due to the high volume of the impact mechanism.
• Reliable firm grip: The tool develops a huge reaction torque (up to 1000 Nm). Always hold the screwdriver firmly with both hands. If a screw jams, a sudden jerk can twist your wrist.
• Preventing overheating: When driving large screws for a long time, pay attention to the heating of the housing and battery. In case of excessive load, let the tool cool down between breaks.
• Safe handling of Li-Ion batteries: Do not expose batteries to open flames, high temperatures above 50°C or moisture. Charge them only with the dedicated charger provided.
• Maintenance and replacement of attachments: Always remove the battery from the housing before changing attachments, cleaning or storing in the case to prevent accidental starting of the device.

It is important to know

The key to choosing a wrench is whether you mainly work with socket wrench screw connections or you also need a tool for drilling and more precise light work. A high torque rating alone does not tell you how well you will be able to control each individual joint.

• An impact driver with a socket wrench holder is a dedicated tool for screw connections, not a universal tool for drilling and screwdriving.
• For lighter or more delicate tasks, check whether the impact design and the way you work with socket wrenches are suitable for you.
• The two included batteries are practical for longer work, but it is not possible to conclude from the data how long each battery will last.

In practice

🔩More demanding screw joints

🟢 Very suitable - the impact design and high stated maximum torque value are aimed at more demanding screw joints. Actual suitability also depends on the specific joint and working conditions.

🪑 Furniture assembly

🟡 Suitable with limitations - during assembly, smaller or more delicate screws may also occur, for which an impact screwdriver with a socket chuck is not the most universal choice.

🧱 Drilling into a wall

🔴 Less suitable - the product is an impact driver, not a drill; the information provided does not confirm the drilling function.

Answers to frequently asked questions

What sockets can I use?

Use socket wrenches with the appropriate 1/2" square drive. Before use, check that the drive fits the tool holder.

Is this model also suitable for drilling?

The data identifies it as an impact driver with a socket wrench holder, not a drill. For normal drilling, therefore, choose a tool with an explicitly stated drilling function.

Do the two included batteries provide enough time for extended work?

Two batteries allow you to have the second one available while using the first. Operating time cannot be determined solely based on the information on the included batteries.
