CAUTION:
Do not turn the adjusting dial when
the tool is running. Failure to do so may result in
the loss of control of the tool and cause an injury.
NOTICE:
If the tool is operated continuously at
low speed for a long time, the motor will get over-
loaded, resulting in tool malfunction.
NOTICE:
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: When the speed adjusting dial is set to "3" or
higher, the tool automatically reduces the speed at
no-load to reduce the vibration under no-load. 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 and there is less
fluidity in grease, the tool may not have this function
even with the motor rotating.
