1.With the conveyor assembly in the oven, stand at one end of conveyor and check tension by lifting the conveyor

belt at the center of the oven chamber opening. The belt should not lift higher that 3to 4(75mm to 102mm).

2.Adjust conveyor belt tension screws (located on left end of oven) for the 3to 4(75mm to 102mm) deflection as shown in Figure 4-26. If there is proper tension, proceed to “J. Attaching Drive Chain”. If belt is still too loose, continue to step 3 below.

3.If conveyor belt is still not under proper tension, an entire link must be removed. Use the following procedure “H. Conveyor Belt Link Removal” to remove a link. If conveyor belt is under proper tension proceed directly to “J. Attaching Drive Chain”.
