Microprocessor electronics: infinitely variable speed preselection, speed stabilization via tachogenerator, overload protection, restart lock, and temperature monitoring. Powerful 1400-watt motor with a high-performance fan for optimal cooling. Gas throttle switch for a slow and sensitive start (starting speed at level 1: 380/min) and locking for continuous operation. Optimized airflow for the best possible cooling effect of the motor and gearbox. No disturbing exhaust for the user. Innovative combination of planetary and angular gears ensures extreme noise reduction. Flat gearbox head reduces the distance to the surface, allowing the machine to be safely operated in any position. Handle cover: ergonomically shaped with SoftGrip. The machine can be guided precisely and always feels comfortable and secure in the hand. The spindle lock is ideally positioned to avoid misuse and not interfere with the grip area. With a rubberized resting surface for safe placement. 4-meter PUR H05-BQF cable: wear-resistant, flexible with high abrasion and notch resistance.
