How to use

Connect the Einhell TC-PW 340 to a compressed-air supply using a hose with an inner diameter of at least 9 mm and ensure the supply pressure does not exceed 6.3 bar. Fit the required socket to the drive, select the desired rotation direction and impact mode (counter-clockwise one-step or clockwise three-step), then apply the tool to the fastener and operate while maintaining a firm grip on the rubberized handle. After use, allow the tool to run briefly without load, disconnect the air supply, and store the wrench and accessories in the provided case. Regularly add a few drops of pneumatic tool oil via the supplied oil bottle to the inlet to ensure proper lubrication.

Recommendations

Use the tool with a suitable air compressor and correctly sized hose (≥ 9 mm inner diameter) to achieve rated performance. Always wear appropriate personal protective equipment, follow vehicle or equipment manufacturers’ torque specifications, and avoid exceeding the maximum working pressure and maximum thread size stated for the tool.
