Q&A
Except for the heavy cutting, this S2 smart polisher can do all the different scenarios of polishing that an ordinary DA polisher can do.
- Why is the RPM set at 2000-4500 and is it enough?
-Initial setting of 2000-5000 RPM, scaled down by 500 revolutions to extend the use of the lithium battery.
-The majority of revolutions in polishing operations are 2000-4000 RPM, so the revolutions range of S2 battery polisher is perfectly adequate.
- Why does the S2s speed go up and down while the gears dont match?
-The S2 realizes the real display of the number of revolutions, most polishing machines have false indication of their parameters, but the S2 is equipped with a device that can measure the real time revolutions and display them in the LCD, so that the user can grasp the real situation.
-The number of revolutions will vary according to the real situation because the output power cannot be constant due to different pressure applied by voltage, etc..
-The sixth gear often appears in idle three parameters: 4050 rpm / 4260 rpm / 4500 rpm, which represents whether the sixth gear can reach the maximum output power, after starting a few seconds can generally reach 4260 or 4500, or a slight pressure to 4500 rpm; there may be a few can only reach 4260 rpm, or when the battery power is insufficient (voltage drop / cold weather) will have the number of revolutions can not reach the 4500 rpm situation. Are normal.
