• Operation and handling
Do not touch the controller or robot during operation.
The controller and robot unit become hot during operation, and
touching them could result in burn injuries.
Do not remove the controller or HT1 covers, and do
not attempt to disassemble or modify them.
Doing so could result in fires or equipment failure.
Do not touch or operate the controller or HT1 with wet
hands.
Doing so could result in electrical shocks or equipment failure.
Immediately turn off the power if abnormal odors,
sounds, or smoke are noticed during operation.
Failing to do so could result in electrical shocks, fires, or equipment
failure. Stop operation immediately, and contact your YAMAHA
representative.
• Maintenance and inspection
Perform maintenance and inspection tasks only when
instructions for doing so are provided by YAMAHA.
Maintenance and inspections performed by a person who lacks the
proper knowledge or training is extremely hazardous.
Shut off the power to the controller before performing
inspections and maintenance tasks.
Shut off the power and wait at least 10 minutes before beginning the tasks.
Failing to do so could result in electrical shocks or burn injuries from
touching areas which are still hot or from touching components where a
high-voltage condition remains for a short period after a power OFF.
