FAQ
Is this sanding arm compatible with other Makita models?
The 125157-7 arm is engineered specifically for the Makita 9032 belt sander. While it may physically attach to other models with similar dimensions, optimal performance and safety are guaranteed only on the 9032.
Do I need any tools to install the new arm?
No additional tools are required. The arm replaces the existing component by aligning the mounting tabs and snapping it into place, making the swap quick and tool‑free.
What is the recommended grit for fine finishing?
For fine finishing, choose a sanding disc with a higher grit number (e.g., 120‑220) that is compatible with the 6 mm arm. The coarse‑grit arm is intended for aggressive material removal, not final surface polishing.
Can I use this arm with a powered belt sander?
Yes, the arm is designed for hand‑powered operation but works equally well on electric belt sanders that accept 6 mm discs, provided the sander’s speed settings are appropriate for coarse‑grit sanding.
What is the warranty period for this product?
Makita offers a standard one‑year limited warranty covering manufacturing defects. Contact Makita customer service with your purchase details for assistance.
