MAINTENANCE UNDER SPECIAL ENVIRONMENTAL CONDITIONS

Precautions for Maintenance During Cold
Weather Season
Before the atmospheric temperature below -0 °C (32 °F), note
the following points.
 Water and oil in the machine will freeze. Never use water
without antifreeze. Use correct windshield washing solution
so that windshield washer tanks and pumps will not freeze.
 Road surfaces may freeze so that tires may slip.
 Oil viscosity changes and oil thickens.
Keeping the above points in mind, follow the below:
1. Refill fluids such as water and lubricants prior to
operation (except fuel).
2. Mix LLC (long life coolant) in the radiator (coolant). When
this machine is shipped from the factory, LLC is supplied.
3. Change the engine oil in the engine crankcase to cold
weather type oil.
4. Use fuel (#1 diesel fuel). To prevent condensation on the
inside wall in the fuel tank, fully refill the fuel tank with
#1 diesel fuel after each shift.
5. If the electrolyte solution in the battery case freezes,
damage to the battery case may result. Keep the
batteries fully charged. After completing work, turn all
lights OFF. When finished with work, run the engine at
low idle for a few minutes to cool down. This will help
rebuild battery charge when lights and other equipment
are off.
In extreme cold, remove the batteries and store them
in a warm indoor place. When it is possible to measure
and adjust the specific gravity of the electrolyte solution,
increase the specific gravity of the electrolyte up to
1.280. Do not increase more than 1.280.
After taking the measures as recommended above, start
operation of the machine.
