4.7.9.c CHECKING THE BATTERY ELECTROLYTE LEVEL
4.7.9.d CHECKING THE OIL LEVEL IN THE TRAV-
EL REDUCTION GEARS
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 wa-
ter and consult a doctor immediately.
The battery (1) can be reached by opening the right side cover.
(See “3.5.2 SIDE COVER”).
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 concentration
suitable for the ambient temperature.
(See “3.10.3 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-oxidation
grease.

DANGER
•
As soon as the machine has been stopped the oil is very
hot; let it cool down until it reaches 40-45°C before carrying
out the check.
This check must be carried out on each reduction gear positioned
with the plug (1) 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 using the prescribed oil.
(See “4.3 FUEL, COOLANT AND LUBRICANTS”).
Use a 8 mm spanner.
