1. Preparation: Disconnect the power tool from the power supply. Place the tool on a stable, clean surface.
2. Remove Old Flange (if applicable): If replacing an existing flange, use the appropriate wrench or tool to loosen and remove the outer flange and any attached accessory. Then, carefully remove the old inner flange from the spindle.
3. Inspect Spindle: Clean the tool's spindle thoroughly, ensuring it is free of debris, rust, or damage. The new inner flange must seat perfectly.
4. Install New Inner Flange: Slide the Makita 224268-6 Inner Flange onto the tool's spindle. Ensure it sits flush against the tool's housing or gear case. The flange should slide on smoothly without excessive force.
5. Attach Accessory: Place the desired grinding wheel, cutting disc, or other accessory onto the spindle, ensuring it sits correctly against the inner flange.
6. Secure Outer Flange: Install the outer flange and tighten it securely with the appropriate wrench. Do not overtighten, but ensure it is firm enough to prevent slippage during operation.
7. Final Check: Before reconnecting power, manually rotate the accessory to ensure it spins freely and is properly centered.
