MANUAL OPERATION
The actuator is supplied with a handwheel for manual override as standard, to operate the actuator in the event
of a loss of power, or during setup and calibration. The handwheel is always engaged. Then handwheel does
not rotate during electric operation. Turn the handwheel clockwise to close, and counter-clockwise to open.
Ensure proper direction of operation using the dial indicator on the actuator.
The reduction ratio of the handwheel is as follows:

E006 and E013 - 73:1, handwheel turns to move 90 degrees - 18

E025 and E051 - 91:1, handwheel turns to move 90 degrees - 23
WARNING: Do not use cheaters, valve wrenches, or similar tools on the handwheel. This can
cause personal injury and damage the equipment.
WARNING: Chain wheels cannot be used. This can cause personal injury and damage the
equipment.
Important: The standard handwheel operation is clockwise (CW) to open, and counter-clockwise
(CCW) to close.
