Remedy
Allow it to cool down before use.
Since heat is sufficiently radiated, periphery of
the main Control Unit should be well-ventilated
wherever possible.
When an error cannot be eliminated, request
repair.
When rotation and stop are repeated in short
frequencies, a circuit may be activated which
limits acceleration at start. Wait a few seconds
and then use.
When an error cannot be eliminated, request
repair.
The chuck may be opened, or may not be
sufficiently closed. Securely close the chuck.
When an error cannot be eliminated, request
repair.
Check the Irrigation tube.
If an error code is displayed even when the
Irrigation tube is normal, request repair.
Check the connection state of the connector.
The error code is displayed even when the
