Grizzly G0503 instruction manual Belt Tensioning Replacing V-Belts

V-Belt Tensioning Replacing V-Belts

Adjusting the V-belts is not an exact science. Adjusting the belts too loose will decrease the performance of the machine, but adjusting the belts too tight may cause premature wear of the components attached to the belts.

To adjust the V-belt tension:

1.Disconnect the resaw from power!

2.Press the center of each V-belt firmly. The belts should deflect between a 1⁄4" and a 1⁄2" (see Figure 65).
