E. Blower Belt

1.Remove the six screws shown in Figure 4-7. Then, remove the rear panel from the oven.

2.Check the blower belt for the proper 1/4(6mm) deflection at the center, and for cracking or excessive wear.

See Figure 4-7. Overtightening the belt will cause premature bearing failure and possible vibrations. A loose belt may also cause vibrations.

3.If necessary, adjust the tension of the belt by loosening the four motor mounting bolts. Reposition the motor as neccessary until the correct 1/4(6mm) deflection is reached, then tighten the bolts.

Remove eight (8) screws to remove rear panel

IV. MAINTENANCE - EVERY 6 MONTHS

A.Check that the oven is cool and the power is disconnected, as described in the warning at the beginning of this Section.

B.Check for excessive wear on the conveyor drive motor brushes. The brushes should be replaced if they have worn to less than 1/4" (6mm) in length. Be sure to replace the brushes in exactly the same position.

C.For gas ovens, inspect and clean the burner nozzle and the spark electrode assembly.

D.Check the conveyor drive shaft bushings and spacers.

Replace the components if they are worn.
