2.
Open the tank compartment, see "PUMP COMPARTMENT
AND BATTERY COMPARTMENT DOORS (3-86)", and
remove the vinyl protection (1) placed on the battery.
3.
Disconnect the battery cables and remove it. (For details,
see "Removing and installing the battery (3-193)").
4.
Remove the battery plug (2).
5.
Check the electrolyte surface through the filling hole (3). If
the electrolyte does not reach the sleeve (4), add distilled
water until the level is at the sleeve bottom (MAXIMUM
reference mark).
q
(A)Correct level: The electrolyte level reaches the
sleeve bottom, so the tension lifts the surface and the
plate seems to be deformed.
q
(B) Level too low: The electrolyte level does not reach
the sleeve bottom, so the plate seems normal.
6.
After topping up, screw in the plug (2).
7.
Refit the battery on the machine, making sure it is well
fixed and connect the cables. (For details, see "Removing
and installing the battery (3-193)").
8.
Put the vinyl cover (1) in position and fix it.
REMARK
q
Do not add distilled water or electrolyte beyond the level indicated, as this would reduce the battery service life
and electrolyte leakage could result.
q
If the distilled water added goes over the MAXIMUM reference mark, take out excess electrolyte with a small
pump and neutralise it with sodium bicarbonate, then rinse out with abundant running water or consult the
Komatsu distributor or the battery manufacturer.
Whenever possible, use an indicator to check electrolyte level
If an indicator can be used to check electrolyte level, proceed as indicated below.
Battery with charge indicator
q
A visual gauge indicates the battery charge level in different colours, according to the table positioned beside
the gauge:
q
Green: optimal charge
q
Gray: the battery needs recharging
q
White: the battery must be replaced.
