General Information

The information on the following pages will
describe how to replace the most common
components of the ST-1 toaster. Though the
instructions are easy to follow, the work should be
done by a qualified service technician. All replace-
ment procedures will first require the removal of
one or both toaster side panels, and top or bottom
covers. 

IMPORTANT: When removing or replacing

the bottom toaster cover, it is extremely impor-
tant that it be positioned correctly. The open side
air cooling vent should be facing towards the
front of the unit. This will assure proper air
circulation and toaster performance.

A      Panel Removal

1.  The right and left side panels are each secured
      to the toaster by one sheet metal screw located
      at the back of the unit. Remove this screw and
      slide

out the panel. When replacing either panel, be
sure that the panel is properly positioned in
the securing track.
