Installation & Service Notes
Prior to installation, ensure the pump is depressurized and isolated. Remove the existing air cover from the 1590-series pump, clean the mounting surfaces thoroughly and inspect for any damage or wear. Position the new 15G668 cover, align bolts and mounting faces, then secure using the recommended hardware and torque specifications. After installation, reconnect the air supply, verify operation under light load, then resume full service while monitoring for proper alignment, sealing and performance.
Maintenance & Care
- Inspect the cover regularly for wear, damage or surface imperfections especially after heavy use or harsh service conditions.
- Clean external surfaces to remove overspray, chemical residues or debris that may impair service access or alignment.
- Ensure all mounting bolts remain tight and that no vibration or looseness is present—looseness may indicate internal misalignment or part fatigue.
