Operation Manual
Motor-drive
The
machine
has
a
belted
motor-drive.
The
belt
should
never
be
too
tight
nor
too
slack
to
ensure
smooth
troublefree
action.
There
should
normaly
be
just
a
slight
give.
As
the
tightness
of
the
belt
may
vary
after
some
time,
you
should
once
in
a
while
take
off
the
ventilation
plate
31
on
the
right-
hand
side
of
the
machine
by
loosening
the
four
fastening
screws.
The
belt
should
be
just
so
tight
that
its
steel
wires
keep
engaging
the
regulating
wheel
29,
causing
it
to
roato
evenly.
The
regulating
wheel
can
be
adjusted
after
loosening
screw
30.
When
retightening
the
wheel
bracket
make
sure
the
rubber
lining
fits
well.
The
motor
requires
no
particular
care.
Only
the
carbon
brushes
will
have
to
be
replaced
after
a
number
of
years.
