SECTION4-MAINTENANCE

III. MAINTENANCE - EVERY 3 MONTHS

IV. MAINTENANCE - EVERY 6 MONTHS

A. Check that the oven is cool and the power is disconnected, as described in the warning on Page 20.

B. Vacuum both of the blower motors, and their surrounding compartments, using a shop vacuum.

C. Tighten all electrical control terminal screws.

D. For split belt ovens ONLY, disassemble, clean and lubricate the conveyor shaft components as described below.

1. Remove the motor shroud, conveyor extensions, and conveyor as described in Part II, Monthly Maintenance.

2. Remove the master links from each conveyor belt. Then, roll the belts up along the length of the conveyor to remove them from the frame.

3. Remove the two conveyor adjustment screws from the idler end of the conveyor frame, as shown in Figure 4- 6.

4. For PS360EWB and PS360WB70 ovens, remove the socket head screw as shown in the inset drawing. Then, loosen the locking collar set screw. Push the shaft assembly toward the locking collar until it is free.

5. Remove the idler shaft assembly from the conveyor.

6. Pull apart the two sections of the idler shaft. Clean the shafts thoroughly using a rag. Then, lubricate both the extended shaft and the interior of the hollow shaft using a light food-grade lubricant.

CAUTION

DO NOT lubricate the shafts using WD40 or a similar product. This can cause the shafts to wear rapidly.

7. Before reassembling the shafts into the conveyor frame, check that they are oriented properly. Remember that unequal-width split belt ovens should ALWAYS have the narrower belt at the front of the oven.

8. Reassemble the idler shaft into the conveyor. For all ovens except the PS360EWB and PS360WB70, make sure that the bronze washer is in place between the two sections of the shaft. See Figure 4-8.

9. Loosen the set screw on both of the conveyor drive sprockets. Then, remove the sprockets from the shaft.

10. Loosen the locking collar set screw, as shown in Figure 4-7. For PS360EWB and PS360WB70 ovens, remove the socket head screw shown in the inset drawing.

11. Push the drive shaft to the right, then lift it free of the conveyor frame. Then, disassemble and lubricate the two sections of the drive shaft as described in Step 5.

12. Before reassembling the shafts into the conveyor frame, check that they are oriented properly. Remember that unequal-width split belt ovens should ALWAYS have the narrower belt at the front of the oven.

13. Reassemble the drive shaft into the conveyor. Check that the nylon spacer is in place, as shown in Figure 4-

8. Also, for all ovens except the PS360EWB and PS360WB70, check that the bronze washer is in place between the two sections of the shaft.

14. Replace the drive sprockets. Reassemble the belts and master links onto the conveyor, and replace the conveyor in the oven.

15. Reassemble the motor shroud and conveyor exten- sions onto the oven.

23

A.Check that the oven is cool and the power is disconnected, as described in the warning on Page 20.

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" (6.4mm) in length.

C.Clean and inspect the burner nozzle and electrode assem- bly.

D.Check (and clean, if necessary) the oven venting system, including the flue.

E.Check the conveyor drive shaft bushings and spacers. Replace the components if they are worn.
