 Always stop the engine, when working on the fuel line.

Always wipe any drip of Diesel fuel or oil. Do not use this equipment
when a leak is found. Repair the equipment before use.

Ensure that there is no fuel leakage on the fuel line after the fuel line
working finished.
Turn the 3-way valve lever to A position.
(Installed tank use position)
Disconnect the P/T 1/2 plugs from the
External Fuel Intake and the External Fuel
Return, and then connect the hoses from
the External Fuel Tank, as shown below.
Turn the 3-way Valve Lever to B
position.
(External tank use position)
Extract the air out from the
connected hoses.
By the above procedure, it makes
possible to use an External Fuel
Tank.
< Note >
 Use always oil-proof hose in 8-10mm
inner diameter as connecting hose.
 The fuel level in the external fuel tank
should be 0 to 3m higher than the bottom
of the equipment. Otherwise, it may
cause engine malfunction or stoppage.
 To avoid any leak from the external fuel
intake and return ports, always turn the lever for 3-way Valve to A position
whenever piping work is performed.
 Use extreme caution when connecting the hoses. If the lever position is set improper,
the fuel may leak from either the Built-in Fuel Tank or the External Fuel Tank.
 Set the fuel intake position 15-20mm above from the External Fuel Intake bottom line,
otherwise water or garbage in the tank may come into the fuel line.
 In order to avoid engine malfunction due to air suction, set the fuel return at the same
level as the fuel intake level in the External Tank.
 Refer air extraction to 『 9-2. Procedures during Operation 』
