PRECAUTIONS WHEN CONNECTING AND DISCONNECTING BOOSTER CABLE
WARNING
When
connecting
the
cables,
never
contact
the
positive
(+)
and
negative
(-)
terminals.
When
starting
the
engine
with
a
booster
cable,
always
wear
safety
glasses
and
rubber
gloves.
Be
careful
not
to
let
the
normal
machine
and
problem
machine
contact
each
other.
This
prevents
sparks
from
generating
near
the
battery
which
could
ignite
the
hydrogen
gas
given
off
by
the
battery.
Make
sure
that
there
is
no
mistake
in
the
booster
cable
connections.
The
final
connection
is
to
the
engine
block
of
the
problem
machine,
but
sparks
will
be
generated
when
this
is
done,
so
connect
to
a
place
as
far
as
possible
from
the
battery.
When
disconnecting
the
booster
cable,
take
care
not
to
bring
the
clips
in
contact
with
each
other
or
with
the
machine
body.
NOTICE
The
size
of
the
booster
cable
and
clip
should
be
suitable
for
the
battery
size.
The
battery
of
the
normal
machine
must
be
the
same
capacity
as
that
of
the
engine
to
be
started.
Check
the
cables
and
clips
for
damage
or
corrosion.
Make
sure
that
the
cables
and
clips
are
firmly
connected.
Check
that
the
safety
lock
levers
and
parking
brake
levers
of
both
machines
are
in
the
LOCK
position.
Check
that
each
lever
is
in
the
NEUTRAL
position.
