UniCarriers FG25T3C - Measures against Cold or Hot Weather; In Cold Weather

IN COLD WEATHER
When using the truck in a cold weather, special
care should be taken more than when using it in a
warm weather.
Caution to be taken when adding fuel
CAUTION
When adding fuel, make sure to shut down
the engine. Never smoke.
Add fuel up to the upper limit of the tank. This will
help prevent the freezing of water content contained
in the air inside the tank or the fuel system from
corroding, which makes it difcult for the engine to
start.
NOTE
Make sure the fuel cap is securely tightened.
(A loose cap will allow rain water or snow to enter
the fuel tank.)
Caution to be taken for the cooling system
CAUTION
Handling LLC
The LLC is flammable. Do not use open
•
ame when adding, changing or storing it.
The LLC is poisonous. Lethal dose: 100
•
cc (3.4 . oz.). Do not swallow it. If anyone
swallowed it accidentally, induce vomiting
immediately and get medical attention.
When storing, put a sign “Dangerous
•
substance” and keep it out of reach of
children.
Frozen cooling water might damage the engine or
radiator.
When the ambient temperature is anticipated
to be below 0°C (32°F), add anti-freeze into the
cooling water. If you do not use anti-freeze, make
sure to remove all the cooling water after the day’s
work. When the truck has a label given above, it
uses cooling water containing 30% LLC (Long Life
Coolant). If this is the case, there is no need to
change the cooling water for 2 years.
The freezing temperature of the cooling water varies
with the mixing ratio of anti-freeze or LLC in it. Mix
anti-freeze or LLC in the cooling water properly
according to the lowest ambient temperature,
referring to the table given below.

Battery care
CAUTION
Never pour hot water over the battery case
even if you nd it difcult to start the engine.
The battery case might break, causing a
serious accident.
The battery hardly freezes and works efficiently
when it is completely charged and has a greater
specic gravity of the electrolyte.
If the electrolyte freezes, the battery case will be
broken. Keep the battery in fully charged condition
at all times.
The battery electrolyte usually freezes at about
-35°C (-31°F) when the battery is in a fully charged
condition.
To prevent freezing
Keep the battery’s state of charge to more than
•
75%.
Keep the specic gravity of electrolyte at 1.280 or
•
less.
When the truck is not in use, remove the battery
•
from the truck and store in a warm place.
