Electronic function
The tools equipped with electronic function are easy to
operate because of the following features.
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.

WARNING:
When using a depressed center grinding wheel /

Multi-disc, flex wheel or wire wheel brush, the wheel
guard must be fitted on the tool so that the closed
side of the guard always points toward the operator.
When using an abrasive cut-off / diamond wheel,
•
be sure to use only the special wheel guard
designed for use with cut-off wheels. (In some
European countries, when using a diamond wheel,
the ordinary guard can be used. Follow the
regulations in your country.)
