Speed adjusting dial
The rotating speed can be changed by turning the speed
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 table below for the relationship between the
number settings on the dial and the approximate rotating
speed.
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.
The tools equipped with electronic function are easy to oper-
ate because of the following features.
•Electronic constant speed control
Possible to get fine finish, because the rotating speed is
kept constantly even under the loaded condition.
•Soft start feature
Soft start because of suppressed starting shock.
•Overload protector
When the tool would be employed over the admissible
load, it will stop automatically to protect the motor and
wheel. When the load will come to the admissible level
again, the tool can be started automatically.
ASSEMBLY CAUTION:
•Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
