built up material in the upper part of the bracket casting.

2.Take the two keys off of the idler pin bracket, wipe off, and re-grease.

3.Reverse the above steps to make the machine ready for reinstallation of the belt according to the Belt replacement instructions.

7.3Installing abrasive discs

1.Disconnect power to the machine to prevent accidental start-ups.

2.Peel off the old abrasive disc.

3.Clean the drive disc surface using naptha or a similar nonflammable solvent that will dry film- free.

4.Pull the protective backing half off the new abrasive disc.

5.Position the new disc carefully so it is centered accurately on the drive disc. (See Figure 8.)

6.When accurately centered, remove the rest of the protective backing and press the abrasive disc firmly against the drive disc so complete adhesive contact is made.

7.Reconnect the power to the machine.

7.4Replacing the v-belt

1.Disconnect power to the machine to prevent accidental start-ups.

2.Remove the belt guard (Figure 9) and disc table.

3.Remove the table tilt lock knob (Figure 10).

4.Loosen the four motor bolts so the motor can slide on its plate.
