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. When tem-
perature is low and there is less fluidity in grease, the tool
may not have this function even with the motor rotating.
