How to use

Insert a compatible 20 V Fieldmann battery and secure it according to the tool’s battery slot instructions. Fit an appropriate disc for the task — a cutting disc for metal or masonry, a grinding disc for welds and material removal, or a flap disc for surface finishing — ensuring the disc diameter and type match the tool’s specifications. Hold the grinder with a firm two-handed or single-handed grip as designed, switch the tool on, and apply steady, controlled pressure while moving the disc across the workpiece. Allow the tool to reach full speed before contact and avoid forcing the disc into the material. After use, switch off the tool and wait for the disc to stop fully before setting the grinder down and removing the battery for storage or charging.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, gloves and hearing protection. Choose discs rated for the material and speed of the grinder, inspect discs before use for damage, and maintain a secure workpiece. Allow the battery to cool between heavy workloads and store batteries in a dry, cool place according to manufacturer guidance.
