sleeve and the outside of the piston rod, which must
not be worn or scratched. Replace worn or damage
parts.

This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
• Never use sharp or pointed tools to remove sleeve
or other components which could result in pump
rupture and cause serious bodily injury. If the
sleeve cannot be removed easily, return the sleeve
and cylinder to your Graco/Airlessco distributor
for
removal.
