WARNING
Special attention should be exercised
when working with retaining rings.
Always wear safety goggles when
working with spring or tension loaded
fasteners or devices.
CAUTION
Do not over-lubricate the Drive Flange Assembly.
Over-lubricating creates a hydraulic effect within
the Torque Limiter which will adversely affect the
break-away torque.
CAUTION
Care must be exercised when sliding the Cylinder/
Piston Assembly onto Hub and into Drive Flange
Assembly to avoid damage to the Rotary Seal.
