4. MOUNTING TO THE VALVE/GEARBOX

Mounting and operation can be in any position.
• Check whether output drive flange suits the valve/gearbox.
• Check whether bore and keyway correspond with the input shaft of the valve or gearbox.
• Degrease mounting surfaces at actuator and valve/gearbox thoroughly.
• Apply lubricant to input shaft of the valve/gearbox.
• Install splined coupling on valve shaft.
NOTE: Fix or support coupling to maintain engagement with actuator.
• Place actuator on the splined coupling and use bolts with a minimum quality of SAE Grade 5 to
fasten. Tighten diagonally.

5. MANUAL OPERATION

The SG handwheel uses an anti-rotation locking system.
• To release, pull the handwheel away from the actuator approximately ¼".
CAUTION: Damage to the locking system may occur if handwheel is not released prior to
operating.
• Rotate handwheel as required. Each time the handwheel is used, it must be disengaged.
