MAINTENANCE EVERY 50 OPERATING HOURS 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: 1.
The battery may be overheated 2. Decrease in the battery acid volume 3. Damage of the electrode plates. 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. 7-43
