I. MAINTENANCE - DAILY
A. Check that the oven is cool and the power is disconnected,
as described in the warning at the beginning of this Section.
B. Clean ALL of the cooling fan grills and vent openings with a
stiff nylon brush. Refer to Figure 4-1 for the locations of the
grills and vents.
C. Clean the outside of the oven with a soft cloth and mild
detergent.
D. Check that ALL cooling fans are operating properly.
CAUTION
If a cooling fan is not operating correctly, it must be replaced
IMMEDIATELY. Operating the oven without adequate
cooling can seriously damage the oven's internal compo-
nents.
E. Clean the conveyor belts with a stiff nylon brush. This is
more easily accomplished by allowing the conveyor to run
while you stand at the exit end of the conveyor. Then, brush
the crumbs off the conveyor as it moves.
F. Remove and clean the crumb trays. Be sure to replace the
trays in the same positions from which they were removed,
because they are NOT identical. Refer to Figure 2-11 (in
Section 2,
Installation).
G. Clean the window (if so equipped) in place.

When all cleaning and servicing is complete:
1. If the oven was moved for servicing, return the oven to its
original location.
2. For gas ovens, reconnect the gas supply.
