Turn the 3way fuel valve lever to the “A” side in order
to prevent fuel from flowing out from the external tank
fuel inlet/return.
Turn the lever completely as far as possible. If the
lever is not completely pressed to either side, it might
not be possible to supply fuel causing the engine to
stop.
Set the supply side so that it is 15 to 20 mm above the
underside of the tank in order to prevent foreign
material or water from being suctioned from inside the
external fuel tank.
Set the external fuel tank return side at the same height as the supply side in order to prevent
poor engine operation due to air mixed in with the fuel.
Refer to section “
9-2 Procedures during Operation
” for air bleeding.
Some air may remain in hoses or pipes immediately after connecting the external fuel tank
resulting in unstable engine speed and engine stoppage.
Do not leave the generator unattended for unmanned operation until you have confirmed that the
engine speed is stable.
10. Inspection/Maintenance
WARNING : ELECTRIC SHOCK/INJURY
Do not touch receptacles or internal electric parts while the generator is
operating.
Do not open the check door during operation. Be careful of pinching or
catching of moving parts such as the cooling fan and fan belt.
Always be sure to stop the engine and remove the engine key when
performing inspection or maintenance.
Do not lift up using tie downs. Use of such could result in the generator
falling.
No persons should be under a suspended generator.
CAUTION : FIRE
Always be sure to wipe up any spilled fuel or oil.
CAUTION : BURNS
Do not touch the engine and surrounding components immediately after
stopping the engine as they are still hot.
Do not open the radiator cap immediately after stopping the engine. Do so
will result in steam gushing out.
Hot steam gushes out from the coolant subtank if the generator overheats.
Do not touch the coolant subtank.
CAUTION : INJURY
Personnel performing suspension work must wear protective gear such as
helmets, safety shoes and gloves.
Always be sure to use lifting hooks when suspending the generator, and raise
it slowly at a completely vertical angle.
Perform periodic inspection and maintenance according to the following table in order to
constantly maintain this generator in good working condition. Use the hour meter as a
reference for the operating time.
