Coolant
Coolant freezing could cause cracks of cylinder and radiator. Be sure to always use mixture of LLC
(antifreezing solution) and soft water (like good quality tap water).

Water with dirt, sand, and/or dust, or hard water such as well water (ground water) will
cause deposits inside the radiator or cylinder head, resulting in engine overheating
due to poor flow of coolant.

Adjust mixing ratio of LLC (Antifreeze) with water according to temperature.
(Machines delivered from the factory have an LLC (Antifreeze) mixing ratio of 55%)
Use an LLC (Antifreeze) mixing ratio between 30 and 60%. See the table below.
(Using an LLC (Antifreeze) mixing ratio of less than 30% may decrease the
antifreezing effect of the LLC (Antifreeze).)
Mixing ratio of LLC (antifreeze) (reference)
Outside temperature (°F) 5 -4 -13 -22 -31 -40 -49
Outside temperature (
℃
) -15 -20 -25 -30 -35 -40 -45
Mixing ratio (%) 30 35 40 45 50 55 60

Use coolant that conforms to SAE J814/SAE J1034/ASTEM D3306.

Follow the designated regulations to dispose of LLC (Antifreeze).
Fuel

Never use fuel with sulfur content greater than 0.0015% (15ppm)
 Use only ultra-low sulfur fuel.

Use such diesel fuel which conforms to standard EN590 or ASTM D975.

Use only clean diesel fuel. Never mix fuel with kerosene or other additives.

Dispose of fuel in accordance with all applicable regulations.
 Diesel fuel is required to meet the following conditions.

Free from even minute dust particles.

High optimum viscosity.

High cetane number.(45 or more)

High fluidity even at low temperature.

Low carbon residue content.
