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 machine 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.

CARE AFTER DAILY OPERATION
CARE AFTER DAILY OPERATION
Drain water from 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.
When ambient temperatures are below use an
anti-freeze mixture per the above table to
prevent freezing of the cooling system.
