Preliminary checks
1– Check the equipment is in good condition and use accessories that are the most suitable for the actuator.
Make sure the torque management system and the handwheel adapter are compatible with the action about to be
carried out.
2– Start the petrol gas motor and leave it to run slowly.
3– If the actuator has a torque limiter, set it to minimum.
4 – Check the rotational direction required for the valve, indicated on the handwheel or the manual. Set the defined
rotational direction using the actuator’s left/right switch.
5 – Position the adaptor on the valve and set up the torque retention system. Consult the instructions for adaptors.
6 – Check the operator is correctly positioned in relation to both the actuator and the torque retention rod. When used, the
actuator (or the torque retention rod) is designed to have a tendency to move away from the operator. This way, if there is a
malfunction, the operator drops the tool safely and it will then move away from him and immediately stop.
