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 mainte-
nance requirement whenever failures occur on
these toasters.
Oil Hole
The conveyor chain should not touch the top
surface of the crumb tray holder. If the chain does
touch, retention it by unplugging the unit, remove
both side covers, loosen the front bearing mount-
ing screws and pivot the bearing until the chain
no longer touches. Retighten bearing screws and
replace side covers
