(3.17 mm) thick, place the threaded locking flange on
the spindle so that the raised section (pilot) fits into the
center of the wheel. If the wheel you are installing is 1/8"
(3.17 mm) thick or less, place the threaded locking flange
on the spindle so that the raised section (pilot) is not against
the wheel.
NOTE: If the wheel spins after the clamp nut is tightened,
check the orientation of the threaded clamp nut. If a thin
wheel is installed with the pilot on the clamp nut against
the wheel, it will spin because the height of the pilot
prevents the clamp nut from holding the wheel.

• Be sure the backing and threaded locking flange are
mounted correctly. Follow the instructions given in the
Accessories Chart.
• Make sure the disc or wheel rotates in the direction of the
arrows on the accessory and the tool.
