4. SELLING POINTS Compact and light weight (Weight: 6.8 kg) Low noise and vibration (Noise level during no-load operation: 4 to 5 dB lower than the conventional Electric brake model) Unique design (Models C 9BU2 only) Most lightweight in the class thanks to the gear cover made of die-cast magnesium alloy Main handle...
(3) Low noise and vibration In the Models C 9U2 and C 9BU2, the ball bearings at the front and the back of the motor are supported by rubber parts and a highly efficient, low-noise and small-diameter fan is adopted. The noise level and the vibration level at start-up and no-load operation are reduced thanks to the above.
