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 explo-
sion.
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 ap-
proximately ten minutes to charge the battery.
WARNING! Approaching or working on a run-
ning 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 ex-
actly the opposite order to which you put them on.
