Electronic function
Constant speed control
• Possible to get fine finish, because the rotating
speed is kept constantly even under the loaded
condition.
• Additionally, 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.
Soft start feature
• Soft start because of suppressed starting shock.
Indication lamp

008416
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
Even locking lever keeping the switch trigger depressed
(Lock-on position) does not allow the tool to restart even
when the tool is plugged.
At this time, the indication lamp flickers red and shows
the unintentional restart proof device is on function.

For smooth removal of a given surface roughness or
texture, tilting the base is helpful. Use the hex wrench to
loosen the two hex socket head bolts securing the base
on either side.
Use a hex wrench to lower the three hex socket head
bolts on the base by turning them on the base clockwise.
