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:
If the tool is operated continuously at low speeds
•
for a long time, the motor may get overloaded,
resulting in tool malfunction.
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.

Do not rotate the change lever when the tool is
