Installation & Maintenance
- Turn off and depressurize the sprayer before performing any maintenance.
- Remove the hopper or loosen the bracket to access the pad location.
- Replace the old pad with the 15D366 isolator pad, ensuring correct alignment under the bracket.
- Tighten bracket bolts to the recommended torque while keeping the pad properly seated.
- Inspect periodically for compression, tearing, or degradation — replace if worn.
Why Replace It?
- Over time, vibration during spraying can compress or damage the pad, reducing its effectiveness.
- A worn isolator pad may allow excessive movement, which can lead to metal fatigue on the hopper bracket or frame.
- Replacing with a genuine OEM pad ensures the structural integrity and longevity of your sprayer setup.
