Metabo DSSW 2440-1" (601551000) 1" Air Impact Wrench

Key specs include a 1" drive, up to 1000 ft-lbs of torque, air-powered operation, variable speed trigger, adjustable torque settings, reversible direction, a rubberized handle for comfort, overload protection, and a design aimed at low vibration for reduced fatigue.

This tool is air-powered, designed to connect to a standard shop air supply via an appropriate air compressor and coupler. It does not require electrical power in use and relies on compressed air for operation.

It is well-suited for heavy automotive work (wheel bolts, hubs), machinery maintenance, and other high-torque bolting tasks on trucks and industrial equipment where 1" drive tools are advantageous.

Connect the tool to a regulated air supply with a proper quick-connect coupling. Use the variable-speed trigger to control speed and torque, select the appropriate torque setting, and run the tool in the desired direction. Ensure sockets are impact-rated for 1" drives, keep hands away from moving parts, and follow standard safety practices for air-powered tools.

The tool incorporates overload protection and a low-vibration design to help reduce user fatigue, along with a rubberized grip for improved handling and control during operation.

You should use impact-rated sockets designed for 1" drives to handle the torque safely and to withstand the hammering force generated by high-torque operations.

Keep the tool clean and free of debris, regularly lubricate the internal components with an inline oiler if your system requires it, drain moisture from the air lines, and store the tool in a dry environment when not in use. Periodically inspect hoses and fittings for wear or damage.

Fepy offers a range of 1" air impact wrenches for different torque levels and configurations.

Consider an inline oiler (to lubricate the tool during use), a set of 1" impact sockets, proper quick-connect fittings, and a suitable air regulator to maintain stable operating pressure for optimal performance.

Consider the required torque (up to 1000 ft-lbs for this model), the 1" drive size, the need for a reversible and variable-speed tool, and the availability of compatible sockets and air supply. If you frequently work with heavy bolting tasks, this model offers strong performance with a robust build.
