Using an antifreeze solution tester, check that the
antifreeze content is sufficient for the existing ambient
temperature. Add antifreeze as required.
Whenever you fill the radiator with coolant after it
has been drained, fasten a tag near the radiator cap. The
tag should indicate the type of coolant and the degree of
protection the coolant gives.
Regardless of the air temperature, be sure to use an
antifreeze solution in the proportions recommended in
the instruction manual for the generator.
The fuel tank should be filled with clean fuel oil,
strained if necessary. Service the fuel tank as follows:
Always maintain constant metal-to-metal
contact between the fuel tank filler neck and the
spout of the fuel supply. That will prevent the
possibility of sparking caused by static
Remove the fuel tank filler cap (fig. 3-1, view B),
and fill the fuel tank with the proper fuel. (Refer to the
instruction manual.) Replace the filler cap and wipe up
any spilled fuel.
Remove the cap from the fuel tank drain valve and
open the valve. Let water and sediment drain into an
approved nonflammable container. When clean fuel
runs out of the tank, close the drain valve and install the
cap on the valve.
A day tank is one of the major components of the
fuel system. It has a capacity to permit engine operation
for a minimum of 5 minutes. The day tank also provides
a settling point for contaminants (to prevent their entry
into the engine) and supplies fuel to the engine fuel
The day tank contains a dual type of float switch.
The upper float operates in conjunction with the fuel
solenoid valve to maintain a predetermined fuel level in
the tank. The lower float initiates an engine shut-down
sequence. This sequence is initiated in the event that the
fuel level in the tank will permit operation of the
generator set at the rated load for only 1 minute.
You must drain sediment and water from the day
tank as you did from the fuel tank. Remove the cap from
the day tank drain valve and open the valve. (Refer to
fig. 3-1, view B, for the location of the tank and its drain
valve.) Drain water and sediment into a container.
Close the valve when clean fuel runs out of the tank, and
install the cap back on the valve.
Do not operate the generator set in an
enclosed area unless the exhaust gases are
piped to the outside. Inhalation ofexhaust gases
will result in serious injury or death.
Keep the area around an operating generator set
well ventilated at all times so that the generator set will
receive a maximum supply of air.
Consider ventilation when you install the units
inside a building. Every internal combustionengine is a
HEAT engine. Although heat does the work, excess
amounts of it must be removed if the engine is to
function properly. This can be accomplished by setting
the radiator grille of the engine near an opening in the
wall and providing another opening directly opposite
the unit. In this manner, cool air can be drawn in and the
hot air directed in a straight line outdoors. These
openings can be shielded with adjustable louvers to
prevent the entrance of rain or snow. In addition, when
the generator is operating in extremely cold weather, the
temperature in the room can be controlled by simply
closing a portion of the discharge opening. Additional
doors or windows should be provided in the shelter if
the plants are installed in localities where the summer
temperatures exceed 80°F at any time.
