MAINTENANCE UNDER SPECIAL ENVIRONMENTAL CONDITIONS

Precautions for Maintenance During Cold
Weather Season
Before the atmospheric temperature becomes down below -0
°C (32 °F), practice the following points.
 Water and oil in the machine will freeze.
 Road surfaces will freeze so that tires may slip.
Keeping the above points in mind, follow the advices below:
1. Refill fluids such as water and lubricants prior to
operation (except fuel).
2. Mix LLC in the radiator (coolant). When this machine
is shipped from the factory, LLC (long life coolant) is
supplied. Therefore, the machine can operate normally
without any problem.
3. Change the engine oil in the engine crankcase to cold
weather type oil.
4. Use fuel (diesel fuel) of an antifreeze type. To prevent
condensation of air into dew on the wall in the fuel tank,
fully refill the fuel tank with an antifreeze type diesel fuel.
5. If the electrolyte in the battery case freezes, damage to
the battery case may result. Maintain the batteries at
fully charged condition. After completing work, turn all
lights OFF. Perform cooling operation for five minutes.
Or by other way, dismount the batteries and store them
in a warm indoor place. When it is possible to measure
and adjust the specific gravity of the electrolyte, increase
the specific gravity of the electrolyte up to 1.280. Do not
increase more than 1.280.
6. Use anti-freeze type washer fluid.
After taking the measures as recommended above, start
operation of the machine.
