A damaged or missing spanner wrench can make accessory changes difficult and may encourage the use of improper tools that could damage the grinder.
Installation & Service Notes
Disconnect the grinder from the power source and allow all rotating components to come to a complete stop before changing accessories.
Depress the grinder's spindle lock and position the 5140186-85 Spanner Wrench so its pins engage the holes in the spindle lock nut. Loosen or tighten the nut as needed while following the grinder manufacturer's instructions. After installing a new accessory, verify that the flange nut is properly tightened and that the wheel rotates freely before operating the grinder.
Important: Always verify your grinder model and original part number before ordering. Use only the proper OEM spanner wrench when servicing the grinder to prevent damage to the spindle nut, flange, or locking mechanism. Never overtighten the spindle nut.
Maintenance Recommendations
- Store the wrench with the grinder for easy access.
- Keep the wrench clean and free of rust or debris.
- Inspect the engagement pins for wear before use.
- Replace the wrench if it becomes bent or damaged.
- Clean the spindle lock nut and flange during accessory changes.
- Use genuine OEM replacement parts to maintain proper fit, safe wheel changes, and long-term grinder performance.
