MAINTENANCE EVERY 50 OPERATING HOURS
7-42
RE-CHARGING A BUILT-IN BATTERY
• Disconnect the cable of the negative pole before re-charging
or pull the battery main switch, in order to interrupt the pow-
er supply. Otherwise, the alternator will be damaged due to
high voltage peaks.
• Remove all battery plugs before re-charging to ensure suffi-
cient ventilation. To prevent gas explosions, do not come
near the battery with fire and do not produce any sparks.
• Interrupt the charging process if the temperature of the bat-
tery acid exceeds 113°F (45° C).
• Switch off the battery charger, as soon as the battery is re-
charged.
If the battery is overloaded, the following situations may oc-
cur:
• Do not mix up the cables (positive (+) and negative (-)).
• Before performing maintenance operations, remove all ca-
bles from the battery poles. Only exceptions: acid level
check or the measurement of the specific density.
1. The battery may be overheated
2. Decrease in the battery acid volume
3. Damage of the electrode plates.
