12. COLD WEATHER OPERATION
1) 1) PREPARATION FOR LOW TEMPERATURE PREPARATION FOR LOW TEMPERATURE
(1) Replace lubrication oil with oil of the prescribed
viscosity.
(2)
Fuel of low pour point must be used. ASTM
D975 No.1 diesel fuel should be used at
ambient temperature lower than -5°C.
(3) When ambient temperatures are below use an
anti-freeze mixture per the above table to
prevent freezing of the cooling system.
Use permanent type antifreeze. Use permanent type antifreeze.
Use soft water (city water, etc.) as mixing water. Use soft water (city water, etc.) as mixing water.
Cooling system must be thoroughly flushed before filling with antifreeze mixture. Cooling system must be thoroughly flushed before filling with antifreeze mixture.
When the climate becomes warmer and antifreeze is not needed, replace with soft water When the climate becomes warmer and antifreeze is not needed, replace with soft water
(city water, etc.) after thoroughly cleaning the cooling system. (city water, etc.) after thoroughly cleaning the cooling system.
Do not expose antifreeze to flame. It is inflammable. Do not expose antifreeze to flame. It is inflammable.
※
Dispose of old antifreeze mixture in locally approved manner. Dispose of old antifreeze mixture in locally approved manner.
2) 2) BATTERY BATTERY
As ambient temperature drops, battery capacity will drop and electrolyte may sometimes freeze if
battery charge is low. Maintain battery at a charge level of over 75% and insulate it against cold
temperature so that truck can be readily started the next morning.
※
When the electrolyte level is low, add distilled water in the morning before work instead of When the electrolyte level is low, add distilled water in the morning before work instead of
after the day's work. This is to prevent fluid from freezing at night. after the day's work. This is to prevent fluid from freezing at night.
3) 3) CARE AFTER DAILY OPERATION CARE AFTER DAILY OPERATION
Drain water from fuel system to prevent freezing.
(1)
Fill the tank at the end of each day of operation to drive out moisture laden air to prevent
(2)
condensation.
Do not fill the tank to top.
Explosive fumes may be present during refueling. Explosive fumes may be present during refueling.
