longer work.
Accidental re-start preventive function
When plugging in the tool while the switch is ON, the
tool does not start.

that the accidental re-start preventive function works.
To start the tool, turn off the switch, and turn it on again.

Constant speed control
Possible to get fine finish, because the rotating speed is
kept constantly even under the loaded condition.

When the load on the tool exceeds admissible levels,

overheating. When the load returns to admissible lev-
els, the tool will operate as normal.
