7.6.8.1 Batteries
The batteries are located in the service sec-
tion in front of the diesel engine under the
cover plate.
Before installing or removing the
batteries, the power supply must be
disconnected via the battery isola-
tor switch. Make certain batteries
are properly and tightly connected.
Dispose of old batteries in compli-
ance with environmental regula-
tions.
The battery manufacturer's instruc-
tions must be observed when using
the batteries for the first time.
It is important that the batteries are always
kept clean to ensure they function properly.
The terminal heads and cable terminals must
be cleaned regularly and then greased with a
thick coating of pole grease.
The level of liquid in the cells should always
be 10 mm above the top of the plates.
If you need to add water, use only distilled
water.
Measure the acid density from time to time
with an acid tester. When the battery is fully
charged, the specific weight is 1.28 kg/l (37%
sulfuric acid).
