BATTERY CHARGING [MICROMATIC M17B]

NOTE

Charge the batteries when the warning light (3) or (4) turns on, or when finishing cleaning.

Keeping the batteries charged makes them last longer.

CAUTION!

When the batteries are discharged, charge them as soon as possible, as that condition makes them last shorter.

Check for battery charge at least once a week.

WARNING!

When using lead (WET) batteries, battery charging produces highly explosive hydrogen gas. Charge the 

batteries in well-ventilated areas and away from naked flames.

Do not smoke while charging this type of batteries.

During the charging of this type of batteries, the recovery water tank (A) must be removed.

WARNING!

When using lead (WET) batteries, be extremely careful while charging the batteries as there may be battery fluid 

leakages. The battery fluid is corrosive. If it comes in contact with the skin or eyes, rinse thoroughly with water 

and consult a physician.

CAUTION!

Batteries must be charged indoors, in a dry environment (damp free).

Preliminary procedures

Drive the machine on a level ground.

Check that the switches (5 and 6) are turned to “0”.

If there is recovery water in the tank (43), drain it through the hose (22).

For lead (WET) batteries only:

Disconnect the vacuum hose (29) from the squeegee (17).

Open the cover (12).

Grasp the recovery water tank (A) in the area (B) and lift it, as shown in the figure, then disconnect the vacuum hose (C) 

from the tank and remove the tank (A) together with the hoses (D) and (E).

Check for the correct level of electrolyte inside the batteries (50). If necessary, add distilled water through the caps.

Leave all the battery caps open for next charging.

If necessary, clean the upper surface of the batteries.

Charge the batteries according to one of the following procedures, depending on the presence of the battery charger (33).
