Function of the Outer Clamp Washer

Using a genuine OEM replacement outer clamp washer helps ensure proper fit, dependable blade security, and long-term tool reliability.
Common Signs Replacement Is Needed
Replace the outer clamp washer if you notice:
- Missing clamp washer
- Bent or warped washer
- Excessive wear on the clamping surface

- Damage from improper installation or overtightening
A damaged or missing clamp washer can prevent the blade from being securely mounted, reducing cutting accuracy and creating unsafe operating conditions.
Installation & Service Notes
Disconnect the saw from the battery or power source before performing any repairs.

Inspect the inner clamp washer, blade bolt, arbor spindle, and blade mounting surfaces for wear or damage before installing the replacement washer. Position the outer clamp washer correctly over the blade, reinstall the blade bolt, and tighten it to the manufacturer's specified torque. Verify that the blade rotates freely and is securely clamped before returning the saw to service.
Important: Always verify your tool model, type number, and original part number before ordering. Use genuine OEM DeWalt replacement components to ensure proper fit, secure blade retention, and long-term circular saw performance.
