SPINDLE LOCK (FIG. 7)
The spindle lock button (A) is provided to
prevent the spindle from rotating when installing or removing wheels. Operate the spindle lock only when the tool is turned off, unplugged from the power supply, and has come to a complete stop. Do not engage the spindle lock button while the tool is operating
because damage to the tool will result. To
engage the lock, depress the spindle lock button and rotate the spindle until you are unable to rotate the spindle further.
Mounting and Using Depressed Center Grinding Wheels and Sanding Flap Discs
MOUNTING AND REMOVING HUBBED WHEELS
Hubbed wheels install directly on the
1.Remove backing flange (D) by pulling away from the tool.
2.Thread the wheel on the spindle by hand.
3.Depress the spindle lock button and use a wrench to tighten the hub of the wheel.
4.Reverse the above procedure to remove the wheel.
NOTICE: Failure to properly seat the wheel before turning the tool on may result in damage to the tool or the wheel.
MOUNTING NON-HUBBED WHEELS (FIG. 8)
Depressed center Type 27 grinding wheels must be used with included flanges. Refer to Accessories and Attachments for more information.
1.Install the backing flange (D) on spindle (B) with the raised section (pilot) against the wheel. Be sure the backing flange recess is
12
seated onto the flats of the spindle by pushing and twisting the flange before placing wheel.
2.Place wheel against the backing flange, centering the wheel on the raised section (pilot) of the backing flange.
3.While depressing the spindle lock button, thread the clamp nut (E) on spindle. If the wheel you are installing is more than 1/8" (3.31 mm) thick, place the threaded clamp nut 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" (3.31 mm) thick or less, place the threaded clamp nut on the spindle so that the raised section (pilot) is not against the wheel.
4.While depressing the spindle lock button, tighten the clamp nut with a wrench.
5.To remove the wheel, depress the spindle lock button and loosen the threaded clamp nut with a wrench.
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.
