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
uidityingrease,thetoolmaynothavethisfunction
even with the motor rotating.
