PREVENTIVE MAINTENANCE
The motors used on the Prince Castle Bun Toasters,
require monthly lubrication, 2-3 drops of 3 in 1 oil.
Motors that fail due to the lack of monthly lubrication
will not necessarily be covered under warranty. We
would like to have field service technicians stress
this maintenance requirement whenever failures
occur on these toasters.
7. The toaster fan located on the bottom of the
toaster in the rear draws in cool room air and
circulates it through the toaster sides and tops.
To insure adequate heat dissipation do not posi-
tion the toaster where the fan would draw in hot
discharge from another appliance.
