Setup

Follow these steps to properly install the backing pad and abrasive paper on your compatible Makita finishing sander.

1. Ensure Power Tool is Off and Unplugged: Before any installation or removal, always disconnect the sander from its power source to prevent accidental startup.
2. Remove Old Pad (if applicable): If replacing an existing backing pad, carefully peel it off the sander's base. Clean any residue from the sander's base if necessary.
3. Attach New Backing Pad: Align the new Makita 4-1/2" x 9" Backing Pad (Model 193522-8) with the base of your Makita Finishing Sander model BO4900V. Press firmly to ensure the hook & loop surfaces engage securely. Ensure the dust extraction holes on the pad align with those on the sander's base.
4. Attach Abrasive Paper: Select the appropriate 4-1/2" x 9" hook & loop abrasive paper for your task. Align the holes on the abrasive paper with the holes on the backing pad. Press the abrasive paper firmly onto the backing pad, ensuring it is flat and securely attached across the entire surface.

Operating

Once the backing pad and abrasive paper are securely installed, you can proceed with sanding operations according to your sander's instructions.

• Always ensure the abrasive paper is clean and free of debris before starting.
• Apply even, moderate pressure during sanding. Excessive pressure can reduce sanding efficiency and damage the pad or sander.
• Regularly check the abrasive paper for wear. Replace it when it becomes dull or clogged to maintain optimal performance and prevent damage to the workpiece.
• Utilize the dust extraction system of your sander to minimize airborne dust and maintain a cleaner work environment.

Maintenance

Proper maintenance extends the life of your backing pad and ensures consistent performance.

• Cleaning: After each use, remove the abrasive paper and gently brush off any accumulated dust or debris from the hook & loop surface of the backing pad. A soft brush or compressed air can be used. Do not use harsh chemicals or abrasive cleaners.
• Inspection: Regularly inspect the hook & loop surface for wear, damage, or loss of adhesion. If the hooks are flattened or damaged, the pad may not hold abrasive paper securely, leading to poor sanding results or detachment during operation.
• Storage: Store the backing pad in a clean, dry place, away from direct sunlight and extreme temperatures. Avoid storing it with abrasive paper attached for extended periods, as this can compress the hook & loop fibers.
• Replacement: Replace the backing pad if it shows significant signs of wear, such as reduced hook & loop adhesion, cracking, or deformation, as this can affect sanding quality and safety.
