How to use

Install the appropriate oscillating accessory for the task, ensuring a secure fit according to the accessory mounting system. Select a suitable speed within the 11,000–18,500 RPM range for the material being worked on: lower speeds for delicate materials and higher speeds for faster cuts in wood or rigid plastics. Hold the tool with a firm grip and guide it steadily along the cut line; allow the tool to perform the cutting motion without applying excessive force. For scraping or sanding, choose the corresponding accessory and maintain consistent, light pressure to avoid overheating the workpiece or accessory.

Recommendations

Use compatible FEIN or manufacturer-recommended accessories designed for oscillating multi-tools. Wear appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when cutting, sanding or scraping. Keep battery charged according to the battery manufacturer's instructions and allow accessories to cool between extended uses to prolong life and maintain cutting quality.
