GENERAL
REMARKS
Before
adjusting
the
unit,
wipe
the
tape
contacting
surfaces
as
well
as
the
rubber
surfaces
of
the
driving
parts
with
a
soft
cloth
soaked
in
alcohol.
Trouble
may
occur
because
of
oil
and
grease
stains.
Carefully
handle
the
belt
because
grease
easily
attaches
to
it.
Then,
check
the
used
rubber
parts.
lf
the
rubber
has
deteriorated
or
is
scratched,
replace
the
part
with
a
new
one.
