Inspection/Maintenance - Shindaiwa DG50MKM-P Owner's And Operator's Manual

< Note >
 If using a hose for the piping, use oil-resistant hose with an internal diameter of 8 to 9
mm.
 Set the fuel level of the external fuel tank from 0 to 3 m from the underside of this
generator. The fuel level of the external fuel tank being lower than this generator will
result in poor engine operation or stoppage.
 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 turn the Power Switch to the OFF
position 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.
