CAUTION:
• If the tool is operated continuously at low
speeds, the motor will get overloaded and
heated up.
• 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.
Electronic function
Constant speed control
Possible to get fine finish, because the rotating speed is
kept constant even under the loaded condition.
Additionally, when the load on the tool exceeds admis-
sible levels, power to the motor is reduced to protect
the motor from overheating. When the load returns to
admissible levels, the tool will operate as normal.
Soft start feature
Soft start because of suppressed starting shock.
