Switch action (Fig. 2)
CAUTION:
• Before plugging in the tool, always check to see that
the slide switch actuates properly and returns to the
"OFF" position when the rear of the slide switch is
depressed.
To start the tool, slide the slide switch toward the "I (ON)"
position. For continuous operation, press the front of the
slide switch to lock it.
To stop the tool, press the rear of the slide switch, then
slide it toward the "O (OFF)" position.
Indication lamp (Fig. 3)
The indication lamp lights up green when the tool is
plugged. If the indication lamp does not light up, the mains
cord or the controller may be defective. The indication
lamp is lit but the tool does not start even if the tool is
switched on, the carbon brushes may be worn out, or the
controller, the motor or the ON/OFF switch may be
defective.
Unintentional restart proof
The tool does not start with the switch being lock-on even
when the tool is plugged.
At this time, the indication lamp flickers red and shows the
unintentional restart proof device is on function.
To cancel the unintentional restart proof, return the slide
switch to "O (OFF)" position, then release it.
Speed adjusting dial (Fig. 4)
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
direction 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
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
operate 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.
