Fuel

1. Determine if the engine fuel is low (Figure 9).

FUEL

EF

Figure 9. Fuel Gauge

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.

CAUTION

DO NOT smoke while refueling. DO NOT attempt to refuel the ride-on trowel if the engine is hot or running.

„„ The sulfur content must not exceed 0.5% by volume. Less than 0.05% is preferred. For electronically-controlled engines, it is mandatory to use fuel that does not contain 0.1% or more sulfur content.

In general, using a high sulfur fuel may possible result in corrosion inside the cylinder. Low sulfur (300-500 mg/kg sulfur content) or ultra low sulfur fuel should be used.

„„ Never mix kerosene, used engine oil, or residual fuels with the diesel fuel.

„„ The water and sediment in the fuel should not exceed 0.05% by volume.

„„ Keep the fuel tank and fuel-handling equipment clean at all times.

„„ 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.

„„ The ash content must not exceed 0.01% by volume.

CAUTION

DO NOT store the Ride-On Trowel with fuel in the tank for an extended period of time. Completely drain the fuel system (tank, lines, etc.) if the unit is to be put into long term storage. For shorter or intermediate periods of time the tank should be filled to avoid condensation that could cause contamination of the fuel.
