Maintenance and Inspection
When disassembling or removing the system, wait until the internal
pressure equals atmospheric pressure and the surface of the system has
cooled to room temperature. Disassembling or removing the system
when it is hot or under pressure may lead to discharge of fluids, causing
burns, other injuries or damage.
CAUTION
Be sure to use only the recommended components when repairing the
system, and NEVER attempt to modify the product in any way. Failure to
observe these precautions may result in damage to the system or burns
or other injury due to malfunction or the discharge of fluids.
CAUTION
Make sure the power supply is OFF before carrying out work on the
wiring or inspections involving disassembly. If such work is carried out
with the power on, there is a danger that components may malfunction
or electric shock may occur, leading to injury or other accidents.
CAUTION
Make sure that installation work requiring a special license is carried out
by qualified personnel. Improper work may cause falls, dropped items,
overheating and electrical leaks, leading to injury, burns, fires, damage
and other accidents.
CAUTION
When using this system, NEVER stand close to, or leave tools anywhere
near moving parts, such as the shaft. Contact with moving parts or
objects becoming caught in moving parts could lead to injury, damage
or other accidents.
CAUTION
Periodically inspect and check the following items as preventive maintenance.
For details regarding maintenance considerations, refer to the individual instruction
manual for each component.
