Preparing
the
Machine
for
the Road
Charge
the
Battery*
To
do
this
the
battery
is
taken
out
of
its
container
after
the
ruobe-r
band
has
been
removed,
the
battery
lid
is
taken
off,
and
the
battery
leads
are
disconnected.
The ba-ttery
is
normally
not
charged
on delivery. Since
special
charging
instructions
have
to
be
observed,
this
wo~k
should
be
done
by
your
NSU
Dealer
or
a qualified
Service Station.
The batt-ery container·
is
provided
with ventilation louvres,
and
it
should
be
used only
to
house
the
battery. Don't
keep
cleaning
rags
or
other
articles in
the
battery
con-
tainer,
since they interfere with
the
proper
ventilation
of
the
battery
and
make
it
difficult
for
the
heat
generat-
ed
to
dissipate. This
in
turn
can
cause
damage
to
the
battery.
