Before You Begin
Important: Always remove the battery or disconnect from mains power before fitting or removing a disc.
Preparation Steps
1. Tool-Free Locking Nut (FixTec)
These instructions apply to RYOBI Angle Grinders equipped with a tool-free locking nut (FixTec).
The FixTec nut has a small tab on one side of the centre thread that flips up, making it easier to tighten or loosen the nut by hand.
If your grinder uses a pin spanner locking nut, refer to: How to remove a RYOBI Angle Grinder disc using a pin spanner.
2. Check Disc Size
Ensure the disc is the correct size for your grinder. See: What size disc is compatible with a RYOBI Angle Grinder?
3. Check Tool and Disc Suitability
Not all angle grinders are designed for cutting or grinding. Confirm your grinder is suitable for the task by visiting ryobi.com.au and reviewing the product description.
4. Wear Gloves
Gloves are recommended when handling or gripping the disc.
Fitting a Disc Using a Tool-Free Locking Nut
1. Remove the battery or unplug the power cord.
2. Position the disc so it sits flush against the inner flange, then place the tool-free locking nut on the spindle/thread.
3. Depress the spindle lock button (usually located on the top of the grinder) to prevent the spindle from rotating.
4. Flip up the black lever on the locking nut and tighten clockwise by hand until secure.
5. Flip the lever back down so it sits flush with the nut.
Removing a Disc Using a Tool-Free Locking Nut
1. Disconnect the grinder from power (remove battery or unplug).
2. Flip up the black lever on the locking nut and press the spindle lock button until the disc and nut stop moving.
3. While holding the spindle lock button, unscrew the locking nut anti-clockwise and remove it to access the disc.
