3.3 Manual Operation
To engage manual operation, depress (by 20°-30°) the lever in the direction shown in
Figure 18 and then let the lever automatically return to its rest position. If no engagement
is obtained, slowly rotate the handwheel and repeat the operation.
Rotate the handwheel to achieve the desired operation (normally clockwise rotation
closes the valve).
A label is located on the handwheel with an arrow showing the closing direction
(clockwise by default). If the closing direction is counterclockwise, the label must be
removed and re-mounted upside-down.
WARNING
Do not manually operate the actuator with devices other than the handwheel and the
declutch lever. Using cheater bars, wheel wrenches, pipe wrenches, or other such devices
on the actuator handwheel or declutch lever may cause serious personal injury and/or
damage to the actuator or valve.
