NOTE:
•Blows at no load per minute becomes smaller than those on load in order to reduce vibration under no load, but this does not show trouble. Once operation starts with a bit against concrete, blows per minute increase and get to the numbers as shown in the table. When temperature is low and there is less fluidity in grease, the tool may not have this function even with the motor rotating.
