3.5 Selector valve of fuel pipe
 Always keep watching the fuel feeding conditions while feeding fuel from a separate fuel storage tank
separately installed.
 In order to use a separator fuel storage tank, be sure to change the handles of the selector valves to a
predetermined position. If you make a mistake in turning the handles, it can burst the fuel pipe and
cause overflowing. It could lead to a serious accident.
 If excessive force is loaded to the selection handle, it will not move smoothly and it could cause fuel
leakage. Be careful about the handle.
3.5.1 Selector valve
This valve is designed to feed fuel directly to the engine of the unit, not from the tank integrated
in the unit, but from a fuel tank installed separately.
3.5.2 Operation method
①
Unit is delivered from factory with fuel line piping and selector valves built in as shown in the
following Fig.1. When operating a unit, using installed fuel tank, run the machine with the fuel
line piping and the handles of selector valves factory-arranged.
②
When using a separate storage tank, remove the plug fitted at the connections to the separator
tank and make piping as shown in Fig.2. And then turn the handles of the selector valve as shown
in Fig.2.
③
When removing the piping connections, make sure to return the handles to the original positions
shown in Fig.1 and install the plugs.
3.5.3 Installation of separate storage fuel tank and piping method
①
Use oil resistant hoses of inside diameter of 8mm to 10mm.
②
Install the fuel tank so that the fuel level of the tank may be kept at the level from zero to 2.5m
high from the machine installation level.
③
In order to avoid suction of water and sediment together, install the suction pipe so that the inlet
port of suction pipe may be kept at the 15mm to 20mm higher level than the bottom line of the
tank. Also install the outlet port of the return pipe inside the tank.(see Fig.2

④
When refilling fuel in the tank, take much care not mix water and sediment.
