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.
CAUTION:
The adjusting dial can be turned only as far as 5
•
and back to 1. Do not force it past 5 or 1, or the
speed adjusting function may no longer work.
