sharpener
unit
Fails
to
drop,
cautiously
push
down
on
lower
unit
as
half
nut
lever
is
activated.
This
condition
some-
times

should
drop
normally.
Holding
the half

lever
in
position
will
cause
the
lower

stop
at
the
bottom
of
the
blade.
This
should
only
be
done
if
it
is
necessary
to
round
the
bottom
of
the
blade
or
to
achieve
an
extra
edge
at
the
bottom
of
the blade .
NOTE: D
If
the

is
stopped
when
the
sharpener
has
been
activated,
it
is

released
by
squeezing
the
lever
on
the
pulley
