Batteries; Starting With Booster Cable - Volvo EC330B Operator's Manual

Starting with booster cable

Because of current surge the batteries may explode if a
fully charged battery is connected to a discharged battery.
Such an explosion can cause injuries.
When starting with booster batteries check that the booster batter-
ies or other power source has the same voltage as the standard

batteries.

Proceed as follows:
1 Turn OFF the battery master switch.
2 Remove the protections from the battery pole studs.
3 Connect two 12 V batteries as follows:
4 Connect one of the jump leads between (+) terminal on the
battery of the machine and the (+) terminal on the booster bat-
tery.
5 Connect the other jump lead between the (-) terminal of the
booster battery and a grounding point on the machine.
6 Connect the batteries of the machine by turning ON the battery
master switch.
7 Start the engine with the ignition key in the cab.
8 When the engine has started, first disconnect the jump lead
from the chassis connection on the machine then disconnect
the other end of the jump lead from the (-) terminal on the
booster battery.
9 Finally disconnect the jump lead between the (+) terminals.
10 Re-install the battery pole stud protections.
Charging batteries
During rapid charging of batteries, always remove the cell
caps. When a battery is being charged, an explosive
mixture of oxygen and hydrogen gas is formed. A short
circuit, open flame or a spark near the battery can cause a
powerful explosion.
– Always turn OFF the charging current, before the charging
lead clips are removed.
– Ventilate well, especially if the battery is charged in a con-
fined space.
– The battery electrolyte contains corrosive sulphuric acid.
Any electrolyte that is spilled on the skin should be re-
moved immediately. Wash with soap and plenty of water.
Should you get splashes of electrolyte in your eyes or on
any other sensitive part of your body, rinse immediately in
plenty of water and contact a doctor immediately.
