CAUTION:
• The speed 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.
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 con-
crete, blows per minute increase and get to the
numbers as shown in the table. When tempera-
ture is low and there is less fluidity in grease,
the tool may not have this function even with the
motor rotating.
