BATTERY
BATTERY
As the ambient temperature drops, the battery capacity will drop and the electrolyte may
sometimes freeze if the battery charge is low. Maintain the battery at a charge level of over 75%
and insulate it against cold temperature so that the 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.
CARE AFTER DAILY OPERATION
CARE AFTER DAILY OPERATION
Drain water from the fuel system to prevent freezing.
Fill the tank at the end of each day of operation to drive out moisture laden air to prevent
condensation.
Do not fill the tank to top.
Explosive fumes may be present during refueling.

PREPARATION FOR LOW TEMPERATURE
PREPARATION FOR LOW TEMPERATURE
Replace lubrication oil with oil of the prescribed viscosity.
Fuel of low pour point must be used. ASTM D975 No.1 diesel fuel should be used at ambient
temperature lower than -5 ˚C.
Use a mixture of 50 percent soft water and 50 percent ethylene glycol antifreeze to fill the cooling
system. Refer to the page 7-66.
