SJS? mechanical clutch system avoids motor and gear damage there by allowing the drive shaft to slip if the wheel is forced to stop. Side handle absorbs vibration thereby allowing to work for long duration without any fatigue. Labyrinth construction offers long lasting durability by preventing the entry of debris to motor， bearings and gears. The electronic controller offers soft start that suppresses start-up reaction for smooth start-ups and longer gear life. Electronic controller also protects the device from any potential damage from overload in high torque applications. Zig-zag epoxy is applied to both sides of the armature coil and a powder coating to provide long lasting durability while protecting from debris. The variable speed control dial allows the user match the speed based on the application requirement.
