Turn off the power, stop the supply of compressed air and make sure that there is no residual
pressure before maintenance.
Plan and conduct daily and periodic inspections so that maintenance can be managed
correctly.
If maintenance is not properly managed, the product's functions may deteriorate significantly and
this may lead to faults (such as short service life, damage, and malfunctions) or accidents.
If an abnormality occurs during operation, immediately stop using the product, turn off the
power, and shut off the pneumatic pressure source.
Conduct periodic inspections at least once a year to confirm that the product operates
properly.
Do not use materials such as solvents, alcohol, or detergent to remove dirt or stains.
The case is made of resin and resin can be damaged by these materials. Use a waste cloth that is
soaked in a diluted neutral detergent and wrung out well to wipe off dirt.
Periodic Inspection
Conduct periodic inspections at least once a year to prevent accidents or problems, such as functional
deterioration, short service life, damage, or malfunctions.
◼ Pressure of supplied compressed air
• Is the set pressure supplied?
• Does the pressure gauge indicate the set pressure during operation of the device?
◼ Pneumatic filter
• Is drainage correctly discharged?
• Is the bowl or element clean enough to use?
◼ Leakage of compressed air from piping connections
• Are all connections, especially at movable sections, correctly connected?
(The product may not operate properly if leakage occurs from piping.)
◼ Operational status
• Is there any delay in operation?
• Are the valves exhausting properly?
◼ Operation of pneumatic actuator
• Are operations smooth?
• Is the actuator reaching the end stop properly?
• Are loads connected properly?
If an abnormality is found, contact your nearest CKD sales office or distributor.
