adjusting dial to a given number setting from 1 to 5.
Higher speed is obtained when the dial is turned in the direc-
tion of number 5. And lower speed is obtained when it is
turned in the direction of number 1.
Refer to the below table for the relationship between the
number settings on the dial and the approximate rotating

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

Constant speed control
Possible to get fine finish, because the rotating speed is kept
constant even under the loaded condition.
Additionaly, 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 admisible levels,
the tool will operate as normal.
Soft start feature
Soft start because of suppressed starting shock.
