Checking The Battery Charge Level - Komatsu SK818-5 Operation & Maintenance Manual

4.8.1.e

CHECKING THE BATTERY CHARGE LEVEL

Check the battery charge level only with the engine at rest.
q
To prevent gas explosions, do not use naked flames, do not smoke and avoid producing sparks due to
q
short circuits.
The battery electrolyte is dangerous: in case of contact with the eyes or the skin, wash with plenty of
q
running water and consult a doctor. The battery is maintenance-free.
IMPORTANT
Make sure that the connection terminals are not oxidized; if necessary, clean them and cover them with
q
anti-oxidation grease.
The battery (1) can be reached after opening the engine hood
(see "3.5.1 ENGINE HOOD".
A visual indicator (2) signals the battery charge level with dif-
ferent colours, according to the table positioned beside the in-
dicator:
Green: the charge is correct
q
Grey: the battery needs recharging
q
White: the battery must be changed
q
If it is necessary to work on the battery, lift the loader
q
arm and secure it with the safety lock, proceeding as in-
dicated in paragraph "3.1.1 LOADER LOCKS".
If a dry battery is installed, check the electrolyte level,
q
which must be approximately 6 mm above the plate
edge; if necessary, top up using distilled water only.
If, on the contrary, the level is low because some elec-
trolyte has been spilt, add sulphuric acid, diluted as
much as necessary to reach the concentration suitable
for the ambient temperature (see "3.11.3 BATTERY").
It is advisable to add distilled water before starting
q
work, in order to prevent it from freezing.
Before putting back the cell plugs, make sure that the
q
breather holes are not clogged.
