Starting Using Auxiliary Batteries; When There Is A Risk Of Freezing - Volvo Penta TAMD71B Instruction Manual

5.6 Starting using auxiliary batteries

Warning!
The batteries (auxiliary batteries in particular) contain extremely explosive oxyhydrogen gas. One
spark, which may be formed if the auxiliary batteries are connected incorrectly, is sufficient to explode
a battery 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 distance from the
discharged batteries, for example at the main switch on the negative cable or at the negative ca-
ble's connection to the starter motor.
3.
Start the engine. NOTE! 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 put them on. NOTE! The nor-
mal leads to the standard batteries should under no circumstances be moved.

5.7 When there is a risk of freezing

Check the antifreeze in the freshwater system after the engine has stopped if there is a risk of freez-
ing. See chap. 4.3 "Coolant".
Drain the water from the raw water system as described in chap. 5.8. Check that all the water has
drained out.
Check the batteries in accordance with instructions in chap. 11.8.1. A poorly charged battery can burst
if it freezes.
