2.If fuel level is low, remove the fuel filler cap and fill with ASTM D975 No1D or No. 2D diesel fuel. Handle fuel safely. Motor fuels are highly flammable and can be dangerous if mishandled.
3.Below are additional technical fuel requirements:
The fuel cetane number should be equal to 45 or higher.
The carbon residue content must not exceed 0.01% by volume. Less than 0.1% is preferred.
The total aromatics content should not exceed 35% by volume. Less than 30% is preferred.
The PAH (polycyclic aromatic hydrocarbons ) content should be below 10% by volume.
The metal content of Na, Mg, Si, and Al should be equal or lower than 1 mass ppm.
Lubricity: The wear mark of WS1.4 should be Max 0.018 in (µm) at HFRR test.
This trowel can use biodesel fuel. Refer to the Yanmar Service manual for details.

Poor quality fuel can reduce engine performance and/or cause engine damage.
Fuel additives are not recommended. Some fuel additives may cause poor engine performance.
