English to Czech Tech/Engineering Mechanics / Mech Engineering pneumatic actuators

An actuator with no pressure and decompressed springs (SR versions) does not have any internal ignition source even if it is in the open position.
Do not modify or tamper with the actuator in any way.
Use only original spare parts provided by the manufacturer.
For bigger size actuators, use only proper lifting, handling and supporting devices.
Before installing an actuator on a ***fault line*** or under extreme weather conditions, please contact XXX Technical-Sales department.
Add electric or non electric accessories only if they comply with ATEX 94/9 EC Directive and come with a Conformity and Classification Declaration suitable for the installation area.
Every time you add an accessory, please verify whether or not you need to carry out the risk analysis required by the Directive above.

Díky!
