BATTERY CHARGING
CAUTION!
Charge the batteries when the yellow (63) or red warning light (64) turns on and at the end of each cleaning
cycle. Keeping the batteries charged make their life last longer.
WARNING!
When the batteries are discharged, charge them as soon as possible, as that condition makes their life shorter.
WARNING!
If the machine is equipped with lead (WET) batteries, battery charging produces highly explosive hydrogen gas.
Charge the batteries in well-ventilated areas and away from naked fl ames.
Do not smoke while charging the batteries.
While charging the batteries always keep the hood open.
WARNING!
Pay careful attention when charging WET batteries as there may be battery fl uid leakages. The battery fl uid is
corrosive. If it comes in contact with skin or eyes, rinse thoroughly with water and consult a physician.
1. Drive the machine on a level ground. Make sure that the machine cannot move independently; if equipped, press the pedal
brake (26).
2. Turn the ignition key (61) to "0".
3. Open the hood (7).
4. (For WET batteries only) check the level of electrolyte inside the batteries (32). If necessary, top up through the caps (38).
Leave all the caps (8) open for battery charging.
If necessary, clean the upper surface of the batteries.
5. Charge the batteries according to one of the following methods, depending on the presence of the electronic battery charger
