REMOVING SANDING SLEEVES

See Figure 3.

Follow these directions to remove sanding sleeves.

Unplug the sander.

WARNING:

Failure to unplug the tool could result in accidental starting causing serious injury.

Grasp and hold the sanding sleeve on the spindle.

Loosen the hex nut using the wrench provided.

NOTE: If the hex nut is too tight and the spindle shaft spins inside the sanding sleeve, grasp the flats on top of the spindle shaft with a 1/4 in. wrench (not provided) and loosen the hex nut.

Remove the hex nut, upper spindle washer, sanding sleeve, rubber spindle, and throat plate.

NOTE: It is recommended that you clean dust accumulations from the throat plate, throat plate nest, and under the lower spindle washer after each use. Remove the lower spindle washer and clean dust accumulations.

INSTALLING SANDING SLEEVES

(All except 1/2 in. (12.7 mm))

See Figure 4.

Follow these directions to install sanding sleeves.

Unplug the sander.

WARNING:

Failure to unplug the tool could result in accidental starting causing serious injury.

Place the lower spindle washer over the spindle, fin side down.

NOTE: Always install the fin side of the washer down. The fins help push dust through the dust exhaust port opening, preventing buildup of dust. Dust in this area may cause the oscillating motion to stop. Always use the lower spindle washer with all sanding sleeves.

Select and install the correct throat plate. Refer to

SELECTING THROAT PLATES/UPPER SPINDLE WASHERS earlier in this manual.

Select and install the correct rubber spindle.

Install the appropriate sanding sleeve on the rubber spindle.

NOTE: If the sanding sleeve becomes difficult to remove or install, apply talcum powder on the rubber spindle or inside the sanding sleeve before installing the sanding sleeve on the rubber spindle.
