Product Overview
The CLAS PW 1080 and PW 1081 are high-performance 1/2" cordless impact wrenches designed for demanding automotive and mechanical tasks. Powered by a 20V brushless motor, these tools deliver a maximum breakaway torque of 1080Nm, ensuring efficient removal of stubborn fasteners. The tool features an electronic clutch system with three forward speed settings and two reverse modes, including an intelligent Auto-Break function for controlled loosening of wheel nuts.
Safety Instructions
Always maintain a clean and well-lit workspace to prevent accidents. Do not operate power tools in explosive environments or near flammable materials. Ensure the tool is switched off and the battery is removed before performing any adjustments, changing accessories, or storing the device. Wear appropriate personal protective equipment, including eye protection, dust masks, and non-slip safety footwear. Keep hair, loose clothing, and jewelry away from moving parts to avoid entanglement.
Operation and Usage
To start the tool, insert a charged battery into the handle until it clicks into place. The trigger is pressure-sensitive, allowing for variable speed control. The electronic clutch allows users to toggle between three forward speeds (1, 2, and 3) using the control panel on the base. In reverse mode, the tool offers a standard full-power setting and an Auto-Break mode. The Auto-Break function, when engaged, stops the tool immediately once the bolt breaks loose and resistance is removed, preventing damage to stud threads. Note that these advanced reverse functions are only available when the clutch is set to the third speed position.
Maintenance and Care
Regular maintenance is essential for tool longevity. Keep air vents and the motor housing free of dust and debris. Clean the tool after each use with a damp cloth and mild soap; avoid harsh detergents that may damage plastic components. Ensure no water enters the tool housing. Recharge the battery at least once per year to maintain its capacity. If the tool requires repair, always use a qualified expert and identical replacement parts to ensure safety. Dispose of electronic components and batteries through authorized recycling services, as they should not be discarded with household waste.
