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 reach the numbers as
shown in the table.
When temperature is low, the tool may not have this
function even with the motor rotating.
