WARNING
Consult CKD about the specifications before using the product outside the designated
specifications or for special applications.

Safety Instructions
3.1.1
Air quality
WARNING
Do not supply anything other than compressed air.
Use clean compressed air that does not contain corrosive gases.
Do not use the exhaust malfunction prevention valves for purposes other than to block the
back pressure from adjacent air devices.
Its structure cannot retain pressure continuously.
CAUTION
Improve the quality of air.
Compressed air usually contains a large amount of drainage, oxidized oil, tar, foreign matters, and
rust from the piping, which may cause malfunction such as an operation fault and short service life.
In addition, the exhaust causes pollution.
Use Class 1 ISO VG 32 turbine oil when lubricating.
Although the product is designed for oil-free operations, if lubricated even once, it will require
periodic lubrication from then on. Make sure to keep it lubricated.
Do not use either spindle oil or machine oil.
They induce expansion of the rubber parts, which will cause operation faults.
◼
Super-dry air
The super-dry air (humidity class of 0 to 3 as specified in JIS B 8392-1) may cause the lubricant to
scatter, resulting in short service life.
◼
Lubrication
Generally, the 4G R Series does not require any lubrication. If lubrication is required, use Class 1 ISO
VG 32 turbine oil.
If there is too much lubrication on the product or if the pressure is significantly low, the response time
may be delayed. The response time indicated in the catalog shows the data obtained when the product
is not lubricated and the pressure is 0.5 MPa.
◼
Drainage
• If the temperature inside the pneumatic piping or pneumatic component drops, drainage may occur.
• If drainage enters and momentarily blocks the air passage inside the pneumatic component, it may
cause an operation fault.
• If drainage generates rust, it may cause a failure in the pneumatic component.
• If drainage flushes the lubricant, it may cause a lubrication failure.
