Makita GA4030K Disk Cover Removal

Check for the provided lock nut wrench. This is used for loosening the piece that keeps the disk and cover attached.

Unscrew the handle unit until it is removed completely.

Hold the black switch located on the front casing.

Still holding the switch, use the lock nut wrench to loosen the silver disk holding everything in place.

Once loose, remove the silver disk and/or your grinding disk.

Use a Phillips #02 screwdriver to remove the 15 mm pan head screw that holds the cover in place.

Remove the cover by lining up the knob on the cover with the notch in face plate.
