Caution:
The retaining rolls of the feed belt unit
exert different degrees of spring pressure,
with the one with a gold-colored spring
exerting greater pressure than the one
with a silver-colored spring.
Check to make sure that the correct roll is
used for each location; there are three
types of springs:
[3] : gold-colored spring (2 pc.)
[4] : silver-colored spring (4 cp.)
[3] : other than [4]; silver-colored spring
(8 pc.)
