ADJUSTMENTS

6. Unscrew the Disc Frame from the sander’s

cabinet. Remove three screws - two on top of the

frame (#38) and one longer screw from the interior of

the frame (#91). FIG. 22.

7. On the cabinet top, under the sanding belt frame,

there are two hex head Bolts and Nuts (#18, 19) that

extend up from the cabinet surface. These connect to

the motor frame and will adjust the tension of the V-

Belt by pivoting the motor. FIG. 16, A , page 13.

Loosen the locking nuts and then rotate the bolts

so that the motor frame is moved to release tension

on the V-Belt.

To gain access to the lower drive Pulley and V-Belt,

the bottom Base Cover (#3) must be removed.

7. Carefully tip the sander to one side to avoid any

damage to the machine. Unscrew the four retaining

Screws (#1) and remove the base cover. FIG. 23.

NOTE: For clarity, FIG. 24 is a bottom view of the

sander with the base cover removed. It shows the

motor, V-belt and pulleys.

8. Remove the old V-belt from the two drive pulleys,

and install a new V-Belt. Make sure that there is some

tension on the belt, so that it does not slip off as the

sander parts are re-assembled.

NOTE: Both pulleys are pre-set at the factory and

should be in-line with each other. If not, re-adjust one

of the pulleys on their drive shaft. Loosen the hex

set screw that holds the pulley to its shaft, move the

pulley so that it is aligned with the other pulley, then

re-tighten the set screw to lock it in position.

9. While the sander is still apart, set the belt tension.

See page 13 for instructions on tightening the two

bolts that apply belt tension. FIG. 17.The sander will

have to be tipped back up to its normal position for

this step.

9. Once the tension on the V-belt is set, re-assemble

the sander parts by reversing steps 7 to 1 above.

The sander is now ready to plug in and use again.
