Handling In Cold Regions - IHI IC75-2 Operation Manual

HANDLING IN COLD REGIONS

At low temperature, the engine hardly starts and coolant is
subject to freezing. Make preparation for cold weather as
shown below.
Fuel
In winter in cold regions, fuel may be frozen and it may be
difficult to start the engine.
Use fuel (light oil) appropriate for the temperature.
Freezing temperature of light oil (as specified in JIS K2204)
Light oil type Freezing point
No. 1 -5ºC or less
No. 2 -10ºC or less
No. 3 -20ºC or less
Special No. 3 -30ºC or less
Coolant
Long-Life-Coolant (LLC) has been mixed in coolant of this
machine before shipment.
The ratio of mixing anti-freezing solution is 50% in all
regions.
Replace the long life coolant every 2000 hours or two
years.
Lubricant and grease
Exchange engine oil and hydraulic oil with proper oil having
viscosity appropriate for the outer temperature. Refer to
RECOMMENDED LUBRICATION TABLE for the specified
viscosity.
Battery
In cold seasons, larger discharge current flows when starting
the engine and the battery performance is also reduced. If the
battery is almost discharged, battery liquid may be frozen.
Recharge the battery almost fully and keep it warm to start the
engine free from troubles next morning.
Precautions when finishing work
• Remove mud and water and water from the cylinder rod to
prevent the cylinder rod seals from being damaged.
• Put plates on dry and solid ground and park the machine on
them in order to prevent the crawlers and around them from
freezing.
• Discharge water from the fuel tank to prevent fuel from
freezing.
