ASSEMBLY
INSTALLING A GRINDING WHEEL OR CUTTING DISC
WARNING - Be sure the tool is switched off and unplugged.
1. Turn the tool upside down.
2. Place the inner flange (I, fig.III) over the spindle so that the two raised
portions tangental to the center hole (d, fig.III) mate with the flats on the
shaft (e, fig.III). The fit should be tight and the inner flange should now
turn with the shaft.
3. Fit the grinding or cutting disc on top of the inner flange, ensuring the bore
fits over the 7/8" raised boss on the inner flange.
4. Screw the disc retaining outer flange nut (f, fig.IV) down over the disc.
Depending on the disc thickness, the boss (g, fig.IV) on the outer flange
nut can face down or up. Normally, it should go down into the 7/8" bore on
the abrasive disc. Very thin cutting discs may require that the boss face
away from the disc so that the flange nut and the inner flange will securely
clamp the disc between them.
5. Fit the two prongs of the wrench (h, fig.V) into the holes in the
outer flange nut (f, fig.IV & V).
6. Depress the spindle lock button (A, fig.I) firmly and ensure the spindle
does not turn.
7. While the spindle lock button is depressed, tighten the flange nut,
turning it clockwise with the wrench.
8. Turn the wheel by hand, checking for any obstruction to its
free movement.
