Precautions

Caution on Design

*Do not use a rotary actuator of the air-hydro type near fire or on equipment or machinery whose ambient temperature exceeds 60°C.
Since the air-hydro type uses a flammable hydraulic fluid, there is a danger of potential fire.
*Do not use in an environment, equipment, or machine that is not compatible with oil mist.
Rotary actuators of the air-hydro type generate an oil mist during operation which may affect the environment.
*Be sure to install an exhaust cleaner on the directional control valve for the rotary actuator of the air-hydro type.
A very small amount of hydraulic fluid is discharged from the exhaust port of the rotary actuator of the air-hydro type's directional control valve, which may contaminate the surrounding area.
*Install a rotary actuator of the air-hydro type in locations where it can be serviced easily.
Since the rotary actuator of the air-hydro type requires maintenance, such as refilling of hydraulic fluid and bleeding of air, ensure sufficient space for these activities.
*Do not use in cases where external leakage of hydraulic oil may adversely affect equipment or machinery.
Although it occurs in minute amounts, a certain amount of sliding leakage from the piston seal is unavoidable with the rotary actuator of the air-hydro type. Because of the construction of the rotary actuator of the air-hydro type, hydraulic oil may leak into the outside due to sliding leakage.

Caution on Selection

*Air hydro-type rotary actuators should be selected in combination with the air-hydro unit.
*Selecting a proper air-hydro unit is necessary for good operation of the rotary actuator of the air-hydro type.
*Use self-align fittings in conjunction with the piping for the rotary actuator of the air-hydro type.
Do not use a single-action fitting with the piping for the rotary actuator of the air-hydro type, as this may result in oil leakage.

*See the manufacturer's catalog for product information other than the above.
