MAINTENANCE OF THE BATTERY AND
BATTERY CONNECTIONS
: Stop the generator before starting
any work on the battery. Ventilate the area
and around the area where the batteries are
placed in proper conditions. Always wear
safety goggles. Battery acid is very corrosive,
be very careful. Do not smoke while you are
working.
Take any equipment that generate flames,
sparks and arcs and all other flammable
sources away from these areas. Explosions,
fires and damages that may occur due to this
may cause serious injuries, and even lethal
accidents. Always disconnect the negative
(-) battery cable firstly, and re-connect the
negative (-) battery cable lastly to decrease
any arcs when you are disconnecting the
battery cables.
Follow the battery manufacturer’s instructions
first for the maintenance of batteries. (Page 5-1)
Check whether the battery connection points are
loose and check for any oxidation. Loose, worn
and oxidized connections cause high electrical
resistance that leads to rough running of the
engine. Before any operation, always:
1. Keep the battery and connection points
clean, dry and tight.
2. Always disconnect battery terminals on
the ends of battery cables using a proper
wrench.
3.
Make certain which terminal is (+) and
which is (-) before making the battery
connections, always disconnect the
negative (-) battery cable first, and re-
connect the negative (-) battery cable
last.
CHECKING ENGINE OIL LEVEL
: Engine oil contact may cause
intoxication. Avoid direct contact with engine
oil and inhale vapors in hot conditions. Use
gloves while you are working. Wash any
parts of your body that had contact with
engine oil.
: Low oil level may cause serious
engine damage. And excessive oil may cause
oil consumption. Always check oil level
before starting the engine.
Check the oil level in the engine with the
dipstick about 10 minutes after stopping the
generator. Add oil or drain oil according to
the required level.
REPLACEMENT OF ENGINE OIL AND FILTER
Refer to the periodical maintenance chart for
regular engine oil replacement. (Page 5-1)
Operate the generator set until it reaches the
proper operating temperature. Stop the
generator and remove the battery negative (-)
terminal.
: Inadvertent or remote operation
of the engine may cause personal injuries or
death. Always disconnect battery terminals
before working on the engine. Always
disconnect the negative (-) battery cable
firstly, and re-connect the negative (-) battery
cable lastly to reduce any arcs when you are
disconnecting the battery cables.
2.
Select a container suitable for the
capacity of the oil and open the manual
oil pump (Page 5-5, Page 5-6, Page 5-7,
Page 5-8 ) valve, and then drain the oil
by moving the pump up and down
manually.
3.
Close the pump valve. Separate old oil
filter with a filter wrench, and clean the
filter installation surface.
4. Apply a thin coat of oil to the gasket on
the new filter and fill the new filter with
some oil so that it can reach engine parts
more quickly.
5. Fill with engine oil of a suitable type and
amount for the engine. See ENGINE OIL
RECOMMENDATIONS (Page 4-2 ).
Check the oil level, and add or drain oil as
required. Operate the engine for a few
minutes, turn the engine off, and check
for proper oil level again.
6. Dispose used oil and oil filter as per the
local environmental legislation.
REPLACEMENT OF FUEL FILTER
: Diesel fuel is a flammable
substance. Uncontrolled ignition or
combustion of the fuel may cause material
damage, and the damages thus occurred may
cause serious injuries, and even lethal
accidents. Do not smoke near fuel tanks or
fuel combustion equipment or any area that
shares the ventilation system with this
equipment. Keep flames, sparks, pilot lights,
electrical arcs, and any other igniters like
switches operated electrically away from
these flammable sources and keep a multi-
class ABC extinguisher in a close place
where you can reach easily during all
maintenance and repair work.
