NOTICE
Be careful not to bump the drive sprocket while
handling the conveyor, to avoid damaging the drive
shaft.
7. Loosen the wing screw on the lower end plug and
remove the lower end plug.
8. Clean the stainless steel conveyor by either
soaking in a hot, strong detergent solution or using
a caustic cleaner.
B. Air Fingers Disassembly and Cleaning
1. Get a felt tip pen. As the air fingers are removed,
you need it to mark all parts of the fingers. This
includes the finger manifold, inner plate, and the
outer plate. If a blank or choke plate is used, mark
that plate also. Fingers are marked in the order
shown; as viewed from the front of the oven. (The
marks for an upper oven should be preceded with
a “U”, example UB1, UT2, etc.)

2. Slide blank plates straight out and remove air
fingers.
NOTE: Some oven users require a custom finger
arrangement where the quantity of air fingers may
vary.
You can remove top and bottom fingers and blank
plates from each or either end. Mark each finger
before removing so it is placed in exactly the same
position when reassembled (refer to step 1).
To remove the air fingers, pull the finger at the back
side and pull straight out (refer to Figure 37).
