Cleaning Outside Of Radiator; Checking Battery Electrolyte Level - Komatsu WB140-2N Operation & Maintenance Manual

CLEANING OUTSIDE OF RADIATOR

• If compressed air, steam or water are directed against a
person, they may cause injuries.
• Always wear safety goggles and safety shoes.
The outside of the radiator must be cleaned with a jet of compressed air
and, if necessary, with low-pressure water or steam washing. The spe-
cific products available on the market can be used, provided that the
instructions given on the package are followed and that the washed
parts are carefully dried at the end of the operation.
Do not use products containing even a small quantity of oily substances, since these facilitate the adhesion of dust, which
affects the heat exchange adversely.
Clean the outside of the radiator whenever the radiator is dirty with oil, diesel oil, greasy or oily substances.
CHECKING BATTERY ELECTROLYTE
LEVEL
• Check the level with the machine parked on flat ground.
• Check the level only after stopping the engine and if nec-
essary add distilled water only before starting work.
• Always wear safety goggles and waterproof gloves.
• To prevent gas explosions, do not use exposed flames.
Do not smoke. Avoid producing sparks due to short cir-
cuits.
• The battery electrolyte is dangerous; if it comes in con-
tact with the eyes or skin, rinse with plenty of water and
consult a doctor without delay.
The battery (1) can be reached after removing the cover (2) fastening
screws (3). Use a 17 mm hexagon wrench.
The electrolyte level in each cell must be about 6 mm (0.24 in) above
the plate edge; if necessary, add distilled water only.
To reach the filling holes of the cells, first remove guard (4). If, on the
contrary, the level is low because some fluid has been spilled, add sulfu-
ric acid, after having diluted it until reaching the concentration suitable
for the ambient temperature. (See "BATTERY"). After finishing, rein-
stall guard (4) and cover (2) with fastening screws (3).
It is advisable to add distilled water before starting work, in order to
prevent freezing.
Before reinstalling the cell plugs, make sure that the breather holes
are not clogged.
Make sure that the connection terminals are not oxidized; if necessary, clean them and cover them with anti-oxidation
grease.
