Safety Precautions
Notes on Maintenance
This machine uses energetic driving systems and high voltage
to run at high speed. This power and voltage is high enough to
cause death or serious injury.

z The maintenance work must be performed with the covers
being attached the machine.
DANGER
Only a well-trained person should perform the maintenance
work for the machine.
Do not allow any untrained person to perform the maintenance
work.

Only qualified personnel should perform the maintenance work
carefully for the machine in compliance with the specified
instructions.
During maintenance, enclose the machine area with a barricade
tape and post "Under Adjustment DO NOT OPERATE"
signboard in a clear and visible place to prevent any third party
from operating the machine. Otherwise, a third party may turn
on the power switch of the machine during the maintenance
work and the machine will start running abruptly, causing an
electric shock or an injury.
WARNING
Before the maintenance work, be sure to turn off the power
breaker and the air source and lock them with padlocks.
Power Breaker: Set the power breaker to the "OFF" side and
lock it with a padlock.
Air Source : Stop the air supply and set the main valve to
the "EXH." side. After that, be sure to lock it
with a padlock.
Designate a person who can have charge of the padlock key.
If the provided padlock is lost or damaged, purchase its

When there is a problem with the machine, locate the cause
and assess the condition. Set the power breaker to "OFF".
After the problem has been rectified completely, reset the
machine to its normal condition.
WARNING
Residual voltages may remain behind for a few minutes in the
internal devices of the machine after power interception.
Touch the internal devices carefully. Otherwise, electric shock
can result from direct contact with live conductors.
