Warning
1) Consult SMC if no leakage is allowed due to the environment, or if the operating
fluid is not air.
2) Polycarbonate resin is used for the external parts including the bowl. Organic
solvents including synthetic fluid, chemicals including acetone, alcohol, ethylene
chloride, sulphuric acid, nitrate, hydrochrolic acid, cutting oil, kerosene, gasoline,
lock material of screw are harmful. Do not use the product where these are present.
Suitability of organic solvents, chemical atmospheres and chemicals in contact with
resin parts. (reference)

When the above factors are present, or there is some doubt, use a metal bowl for
safety.
3) Avoid the application where charge and discharge of pressure to the resin bowl is
switched frequently.This may damage the bowl. A metal bowl is recommended in
these cases.
4) Protect from ultra violet ray and radiation heat by shield.
