Essential Parts Involved in Blade Removal

To safely remove the blade from your DeWalt compound miter saw, it’s crucial to understand the essential parts involved in the process. Familiarizing yourself with these components will help ensure a smooth and secure blade replacement.

1. Blade Guard

The blade guard is a protective covering that shields the saw blade when unused.
To access the blade for removal, you’ll need to lift or open the blade guard.
Many DeWalt miter saws have a lever or knob that allows you to do this.
The blade guard is designed to prevent accidental contact with the sharp blade and should always be in the closed position when the saw is not in use.

2. Spindle Lock

The spindle lock is a critical safety feature that prevents the blade from rotating while you’re working on it.
It’s usually a button or lever located near the blade housing.
To engage the spindle lock, you’ll typically need to press it down while manually rotating the blade until it locks into place.
This ensures the blade remains stationary as you loosen and remove the blade nut.

3. Blade Nut

The blade nut, also known as the arbor nut, is a threaded fastener that secures the blade to the saw’s spindle.
It’s located at the blade’s center, which aims to hold the blade in place during operation.
You’ll need to loosen and remove the blade nut to remove the blade.
DeWalt miter saws often come with a wrench specifically designed for this purpose.

4. Blade Washer(s)

Blade washers are thin, flat, metal or plastic discs on either side of the blade.
They help distribute the pressure evenly when the blade nut is tightened, ensuring it is properly secured and aligned.
Depending on your miter saw model, there may be one or two washers that need to be removed along with the blade.

5. Blade

The blade itself is, of course, a crucial part of the process.
It’s the cutting tool that you’ll be removing and replacing.
Ensure that the new blade you intend to install is compatible with your DeWalt compound miter saw in size and type.

Blade Removal Process

Spindle Lock: Engage the spindle lock to immobilize the blade.
Loosen Blade Nut: Use the provided wrench to loosen and remove the blade nut by turning it counterclockwise. Keep the nut and any washers you remove in a safe place.
Remove the Blade: Carefully lift the old blade off the spindle and set it aside.
Inspect and Replace: Examine the new blade for any defects, ensure it’s oriented correctly, and proceed to install it.
