Starting the engine using auxiliary
batteries
WARNING! The batteries (auxiliary batteries in particular) con-
tain extremely explosive oxyhydrogen gas. One spark, which
may be formed if the auxiliary batteries are connected incor-
rectly, is sufficient to cause a battery to explode and cause
damage and injury.
1. Check that the auxiliary batteries are connected (in series or in
parallel) so that their rated voltage is the same as the engine’s
system voltage.
2. First connect the red jump lead (+) to the auxiliary battery, then
to the discharged battery. Then connect the black jump lead (–)
to the auxiliary battery, then to a spot a short distance from
the discharged batteries, for example at the main switch on
the negative cable or at the negative cable’s connection to the
starter motor.
3. Start the engine.
WARNING! Do not shift the connections when attempting
to start the engine (spark risk) and do not lean over any of
the batteries.
4. Remove the jump leads in exactly the opposite order to which
you connected them.
WARNING! Do not under any circumstances move the
normal leads to the standard batteries.
