CAUTION:
If the tool is operated continuously at low speeds
•
for a long time, 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
The tools equipped with electronic function are easy to
operate because of the following features.
Constant speed control
Constant speed control provides fine finish by keeping
the rotating speed constant under the loaded condition.
Soft start feature
Soft start feature suppresses starting shock.
Overload protector
When the load on the tool exceeds admissible 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.
