The restart protection features a safety switch to prevent unintentional starting after a power failure. The spindle guard is optimally positioned for convenient handling. The motor has a very high copper content for enhanced performance. A special flange nut allows for easy and secure disc changes. The very flat gear housing enables trouble-free use in tight spaces. Self-shutting carbon brushes extend the motor's lifespan. The special jetstream cooling channel filters abrasive dust particles from the air, effectively protecting the motor and increasing the device's lifespan. Tool-free quick adjustment of the protective cover allows for versatile applications. This compact one-handed angle grinder has a very small housing diameter. The electronic soft start function prevents abrupt starting of the machine. Epoxy resin-coated windings increase the motor's lifespan.
