• Measure the electrolyte density of individual cells with a
commercial hydrometer. The hydrometer reading (see table
on following page) indicates the battery’s state of charge.
During measurement, the temperature of the electrolyte
should preferably be 20 °C.
Attention
The gases emitted by the battery are explosive! Keep sparks
and naked flames away from the battery!
Do not allow battery acid to come into contact with skin or clot-
hing!
Wear protective goggles!
Do not rest tools on the battery!
6.8 Grease lubricated generator backend bearing
A bearing change should only be executed by a trained expert.
The bearing is, depending on the generator model, equipped with a black cooling disc.
The grease lubricated generator bearing is maintenance free over its durability, but should be exchanged every
1500 operating hours.
