Belt Replacement
It is very important to replace all belts at the same time!
If the drive belts have to be replaced, follow the procedure from
“Drive Belt Tension” through Step 6. When the point is reached,
release the belt from tension by fully unscrewing the tie rods. Slip off
the belts and replace them with new ones. Continue with the procedure
for adjusting the belt tension.

procedure!
1. Switch the machine OFF and lock out power by turning the
