Auto-Fill Shut Off (S); Refilling The Reservoir - Graco Dyna-Star 24Y408 Instructions, Repair And Parts

Auto-Fill Shut Off (S)

The Auto-Fill Shut Off (S) is used for refilling the grease
tank/reservoir in an automatic lubrication system.
NOTE: For systems without a fill valve, see Refilling
Systems without a Fill Valve instructions beginning on
page 13. For systems with a fill valve, see Refilling
Systems with a Fill Valve beginning on page 14.
As grease is added to the reservoir, it pushes the dia-
phragm up to the top of the reservoir. The diaphragm
then pushes the valve pin and closes the inlet fluid path.
When the fluid refilling path closes, the refilling line (D)
pressurizes and brings the refilling pump (P) to a pres-
surized stall condition.
NOTE: The operator must monitor system while filling
tank to reduce the risk of accidental fluid overflow.
