Always use diesel oil for the fuel.
To ensure good fuel consumption characteristics and exhaust gas characteristics, the engine
mounted on this machine uses an electronically controlled high-pressure fuel injection device.
This device requires high precision parts and lubrication, so if low viscosity fuel with low
lubricating ability is used, the durability may reduce considerably .
Note.1: HTHS (High-Temperature High-Shear Viscosity 150 degrees C), specified by ASTM D4741 must
be equal to or higher than 3.5 mPa-S. Maeda SAE 0W30 and SAE 5W40 are the most suitable
oils.
Note.2: Powertrain oil has different properties from engine oil. Be sure to use the recommended oils.
Note.3: Supercoolant (AF-NAC)
(1) Supercoolant has the important function of anticorrosion as well as antifreeze.
Even in the areas where freezing is not an issue, the use of antifreeze coolant is essential.
Maeda machines are supplied with Supercoolant AF-NAC. Supercoolant AF-NAC has excellent
anticorrosion, antifreeze, and cooling properties and can be used continuously for 2 years or 4000
hours. Supercoolant AF-NAC is strongly recommended whenever available.
(2) For details of the ratio when diluting Supercoolant with water, see “Maintenance 10.2 Irregular
Maintenance [4] Clean inside of coolant system”.
Supercoolant AF-NAC may be supplied in premix. In this case, always top off with premix solution.
(Never dilute with water)
(3) To maintain the anticorrosion properties of Supercoolant AF-NAC, always keep the density of
Supercoolant between 30% and 68%.
