Starting using auxiliary batteries
WARNING! Batteries produce oxyhydrogen. This
gas is easily ignited and highly volatile. A short-
circuit, naked flame or spark can cause a large
explosion. Ensure that the ventilation is good.
Never mix up battery positive and negative
terminals. This may cause sparks and an
explosion.
1. Check the auxiliary batteries have the same rated
voltage as the engine's system voltage.
2. First connect the red jump lead to the discharged
battery's + terminal (A) and then to the auxiliary
battery's + terminal (B).
3. First connect the black jump lead to the auxiliary
battery's - terminal (C) and then to a site (D)
where there is good contact with the cylinder block
as far away from the discharged battery as
possible.
4. Start the engine and run it at a fast idle for
approximately ten minutes to charge the battery.
WARNING! Approaching or working on a running
engine is dangerous. Watch out for rotating
components and hot surfaces.
Do not touch the connections while trying to start
the engine: This may cause sparks. Do not lean
over the batteries.
5. Stop the engine. Remove the jump leads in
exactly the opposite order to which you put them
on.
