2. Check to see if the belt (A) Fig. 4, is tensioned
properly by applying light pressure to the belt at the
center span of the pulleys as shown. NOTE: THERE
SHOULD BE APPROXIMATELY 1/4 INCH DEFLEC-

6mm hex wrench, until correct tension is obtained. Then
tighten locknut (G).

sary, move the sanding arm to the horizontal position.
