Checking The Battery Electrolyte Level; Checking The Oil Level In The Travel Reduction Gears - Komatsu PC27R-8 Operation & Maintenance Manual

MAINTENANCE PLAN
4.7.7.b CHECKING THE BATTERY ELECTROLYTE LEVEL
DANGER
Check the level only after stopping the engine and if necessary add distilled water only before starting
work.
Always wear safety goggles and waterproof gloves.
To prevent gas explosions, do not use naked flames, do not smoke and avoid producing sparks due to
short circuits.
The battery electrolyte is dangerous; if it comes in contact with the eyes or skin, rinse with plenty of
water and consult a doctor without delay.
The battery (1) can be reached by opening the right door (2).
The electrolyte level in each cell must be about 6 mm above the
plate edge; if necessary, top up with distilled water only.
If, on the contrary, the level is low because some fluid has been
spilled, add diluted sulphuric acid until reaching the concentra-
tion suitable for the ambient temperature.
(See "3.11.3 BATTERY").
IMPORTANT
It is advisable to add distilled water before starting work,
in order to prevent it from freezing.
Before putting back 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-oxida-
tion grease.
4.7.7.c CHECKING THE OIL LEVEL IN THE
TRAVEL REDUCTION GEARS
DANGER
As soon as the machine has been stopped the oil is very
hot; let it cool down until it reaches 40÷50°C before carry-
ing out the check.
This check must be carried out on each reduction gear posi-
tioned with the drain plug (1) downward and aligned with the lev-
el plug (2) on the vertical axis.
If necessary, move the machine slightly until reaching the re-
quired position, which must absolutely be respected in order to
carry out a precise check.
This check is visual: the oil must reach the hole (2); otherwise,
top up following the procedures described in paragraph "4.7.10.a
CHANGING THE TRAVEL REDUCTION GEAR OIL" and using
the prescribed oil.
(See "4.3 FUEL, COOLANT AND LUBRICANTS").
Use a 8 mm setscrew spanner.
