Service Notes

• Never use sharp or pointed tools to remove the sleeve. If it will not come out easily, return the sleeve and cylinder to a Graco distributor for removal (Graco manual 310643).
• Do not clean or wipe the piston valve threads. Cleaning them could destroy the special sealing patch and let the piston valve come loose during operation (Graco manual 310643).
• Relieve pressure with the Pressure Relief Procedure before cleaning, checking or servicing the pump (Graco manual 310643).
