Q: How do I change the backing pad?
Peel the worn pad from the sander's drive plate and press the new grip-faced pad firmly into place, aligning the holes with the sander's dust ports.
08K3461 - Mirka 3" × 4" Grip-Faced Multi-Hole Vacuum Backing Pad

To help achieve high-quality, consistent results with a Mirka 3" × 4" SGV pneumatic sander, this backing pad helps maintain even contact on flat or contoured surfaces.
Used with hook-and-loop-backed 3" × 4" abrasives, it is made of a durable, resilient material that resists wear and deformation through long use. The 29-hole pattern permits good airflow behind the abrasive, which extends its life and avoids damaging surfaces with stray grit particles.
