The overheat prevention device has been
activated.
Allow the equipment rest for about 10
minutes. The operation will resume after
that.
Overheat prevention device
A protection circuit to prevent abnormal overheating of the
inner mechanism due to continuous operation. When this
device is activated, the equipment will not operate temporarily.
The main switch is turned
off when the service outlet
is used.
Is the total current consumption
with rated tolerance
?
Is the appliance plugged in
the service outlet working
without short-circuit
?
When total current consumption exceeds
the rated tolerance, the breaker function
starts to work.
Decrease your current consumption to be
within tolerance and turn on the power.
The operation will resume after that
(See Page 17).
Test this using a different apparatus. If the
power switch is still turned off when the
service outlet is used by a different
apparatus, please contact your dealer or us.
Breaker function
The power switch also functions as a breaker.
If the appliance is short-circuited or the current
consumption exceeds the rating, the power
switch is automatically turned off. Turn on the
power after the fault condition is cleared.
The operation should resume.
The following is not trouble.
Abnormal sound is heard at startup.
This is a phenomenon caused when the inner lubricant oil is cooled.
The equipment functions normally. The sound will disappear after a while.
When the operation does not resume after checking the possible causes and taking possible
countermeasures, please refrain from using the chair, turning off the power, and unplug the power
cord, and contact your dealer or us.

circuited
