Safety Precautions
NOTICE
• Do not plug or unplug the E-ECU for a period of
at least 6 seconds after power to the unit has
been turned on or off.
• Do not touch connector pins of the E-ECU with
bare hands.
Doing so may result in corrosion of the connector
pins and/or damage to the internal circuits of the
E-ECU due to static electricity.
• Do not force a measuring probe into the female
coupler.
Doing so may cause contact failure of the
connector pins, resulting in malfunction of the E-
ECU.
• Take care to prevent water from entering the
couplers when plugging or unplugging the
connector.
Water inside the couplers may cause corrosion,
resulting in malfunction of the E-ECU.
• Avoid plugging/unplugging the connector more
than approx. 10 times.
Frequent plugging/unplugging of the connector
may cause contact failure of the connector pins,
resulting in malfunction of the E-ECU.
• Do not use the E-ECU that has ever suffered drop
impact.
NOTICE
• Never permit anyone to operate the
engine or driven machine without
proper training.
• Read and understand this Operation Manual
before you operate or service the machine to
ensure that you follow safe operating practices
and maintenance procedures.
• Machine safety signs and labels are additional
reminders for safe operating and maintenance
techniques.
