[Precautions in using biofuel]
1. Free methanol in FAME can corrode FIE (fuel injection equipment) part made from aluminum and zinc.
2. Free water in FAME can cause clogging of the fuel filter and increase generation of bacteria.
3. Viscosity can become high when cold, which makes it hard for fuel to flow. Besides, an operation error of the fuel
injection pump or faulty atomization of the injection nozzle may be caused.
4. FAME may adversely affect a part of rubber materials (sealing parts, etc.). This causes fuel to leak, which causes
lubricating oil to be diluted.
5. Even when biodiesel fuel conforming to appropriate standards is used, attention needs to be paid to maintain fuel
quality in the equipment and fuel tank. It is important always to replenish clean and new fuel. It is sometimes
necessary to periodically wash away contamination of the fuel system and fuel storage vessel.
6. When biodiesel fuel, which does not conform to the standards specified by a diesel engine manufacturer and
diesel fuel injection equipment manufacturer, is used, or deteriorated biodiesel fuel as described in the above
precautions is used, this may not be covered by engine manufacturer's warranty.
4.4.4 FUEL FEED TO FUEL SYSTEM
In the following cases, it is necessary to feed fuel to the fuel system before starting the engine.
•
Before starting the engine for the first time
• After fuel runs out and the fuel tank is replenished with fuel
•
After maintenance and inspection of the fuel system is performed
such as replacement of the fuel filter, drain of the oil/water separator
and replacement of fuel system parts
Feed fuel to the fuel system following the procedure below.
•
Turn the main starter switch of the vehicle to the ON position and
hold it for 10 - 15 seconds. This enables the solenoid feed pump to
feed fuel to the fuel system.
Never turn the starter switch to feed fuel to the fuel system. Otherwise, the starter may be heated, which may break
the coil, pinion gear, ring gear, etc.
