III. MAINTENANCE - EVERY 3 MONTHS
1. Check that the oven is cool and the power is
disconnected, as described in the warning at the
beginning of this Section.
2. Vacuum both of the blower mounts, and their
surrounding compartments, using a shop vacuum.
3. Tighten all electrical terminal screws.
4. Conveyor Belt Disassembly and Cleaning
Refer to Part D, Conveyor Installation, in the
Installation section of this Manual. Then,
remove the following components from the
oven:
o
Conveyor end stop
o
Crumb trays
o
Chain cover
o

Conveyor assembly
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.
Remove the two conveyor adjustment screws
from the idler end of the conveyor frame, as
shown in Figure 30.
Remove the idler shaft assembly from the
conveyor.
Clean the shafts thoroughly using a rag.
Before reassembling the shafts into the
conveyor frame, check that they are oriented
properly and assess the condition of the
bronze bushing, replacing if worn or
questionable.
Disassembling the Idler Shaft
Reassemble the idler shaft into the conveyor.
Make sure that the bronze bushing is in
proper position. See Figure 30.
Replace the conveyor adjustment screws as
shown in Figure 30. To allow the conveyor
belt to be reinstalled later, do not tighten the
screws at this time.
Loosen the set screws on the conveyor drive
sprocket. Then, remove the sprocket from
the shaft.
Check the conveyor configuration as follows:
High-speed conveyors are equipped with
large flange bearings at the drive end of the
shaft. For these conveyors, remove the two
screws that hold each bearing to the
conveyor frame. With the screws removed,
lift the end of the shaft at the front of the
oven, and pull the entire assembly free of the
conveyor frame.
Idler conveyor side is equipped with bronze
bushings mounted on spacers at the idler
