Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
• Install an air line lubricator for automatic air motor lubrication
• Install a bleed-type master air valve to relieve trapped air
• Follow torque specifications for assembly (e.g., pump cylinder to extension tube: 45–55 ft-lb; shovel rod to piston: 25–30 ft-lb; piston to extension rod: 25–30 ft-lb)
• Do not use slots in shovel tube to tighten or loosen tube
• Read and follow all safety and installation instructions in the manual
• Regularly inspect and maintain air motor and lubrication system
• Use only recommended non-corrosive and non-abrasive greases and lubricants
• Check for leaks and wear on seals and moving parts
• Consult the manual for detailed maintenance procedures
