Connections to a Building's Electrical System
Connections for standby power to a building’s electrical system must be made by a qualified
electrician. The connection must isolate the generator power from utility power, and must
comply with all applicable laws and electrical codes.
Improper connections to a building’s electrical system can allow electrical current from the
generator to backfeed into the utility lines. Such backfeed may electrocute utility company
workers or others who contact the lines during a power outage. Consult the utility company or a
qualified electrician.
Improper connections to a building’s electrical system can allow electrical current from the
utility company to backfeed into the generator. When utility power is restored, the generator
may explode, burn, or cause a fire in the building’s electrical system.

3.3.4
GFCI (Ground-fault circuit interrupter) Receptacles
Using the generator in rain, snow or near water can lead to death from electric shock. Keep the
generator dry.
All of the 20 ampere 120 volt receptacles on the generator are protected by a GFCI
(Ground-fault circuit interrupter) for protection against the hazards of ground fault currents.
An example of ground-fault current is the current which would flow through a person who is
using an appliance with faulty insulation and, at the same time, is in contact with an
electrical ground such as a plumbing fixture, wet floor, or earth.
The ground-fault circuit interrupter will not protect against short circuits or overloads. The
circuit breaker in the control panel which supplies power to the circuit provides that
protection.
The ground-fault circuit interrupter can be identified by the TEST and RESET buttons. The
receptacles on the GFCI can be tested with the TEST and RESET buttons.
TEST BUTTON: To test, depress the “TEST” button. (power is turned off)
RESET BUTTON: To restore power, depress the “RESET” button.
Perform this test monthly or every 250 hours operation whichever comes first, in order to ensure
proper operation of the GFCI receptacle. If the generator is stored outdoors, unprotected from the
weather, test the GFCI receptacle before each use. Record your test on the GFCI test card provided
on the control panel.

Selecting Cable
Select a cable with sufficient diameter by considering the permissible current on the cable and the
distance from the generator to the load.
If the current flowing to the load exceeds the permissible current of the cable, resultant
overheating may burn the cable. Similarly, if the cable is too small in thickness to the length, the
input voltage to the load will fall to cause the load input power to drop, as a result, the performance
of the machine cannot be displayed.

Selector Valve of Fuel Pipe
Always keep watching the fuel feeding conditions while feeding fuel from a separate fuel storage tank
separately installed.
In order to use a separator fuel storage tank, be sure to change the handles of the selector valves to a
predetermined position. If you make a mistake in turning the handles, it can burst the fuel pipe and
cause overflowing. It could lead to a serious accident.
If excessive force is loaded to the selection handle, it will not move smoothly and it could cause fuel
leakage. Be careful about the handle.
3.5.1
Selector valve
This valve is designed to feed fuel directly to the engine of the unit, not from the tank integrated
in the unit, but from a fuel tank installed separately.
3.5.2
Operation method
① Unit is delivered from factory with fuel line piping and selector valves built in as shown in the
following Fig.1. When operating a unit, using installed fuel tank, run the machine with the fuel
line piping and the handles of selector valves factory-arranged.
② When using a separate storage tank, remove the plug fitted at the connections to the separator
tank and make piping as shown in Fig.2. And then turn the handles of the selector valve as shown
in Fig.2.
③ When removing the piping connections, make sure to return the handles to the original positions
shown in Fig.1 and install the plugs.
3.5.3
Installation of Separate Storage Fuel tank and piping method
① Use oil resistant hoses of inside diameter of 8mm to 10mm.
② Install the fuel tank so that the fuel level of the tank may be kept at the level from zero to 2.5m
high from the machine installation level.
③ In order to avoid suction of water and sediment together, install the suction pipe so that the inlet
port of suction pipe may be kept at the 15mm to 20mm higher level than the bottom line of the
tank. Also install the outlet port of the return pipe inside the tank.(see Fig.2・A)
④ When refilling fuel in the tank, take much care not mix water and sediment.

Be sure to use CD class engine oil or superior class. (Using engine oil with poor quality may shorten the
life of the engine).
When two or more different brands of oil are mixed, its performance can be deteriorated. Do not mix oils.
Follow the designated regulations to dispose of engine oil.
4.4.2
Coolant
Quality of coolant and antifreeze
Use soft water of good quality such as tap water for coolant.
When water with dirt, sand, and/or dust contained, or hard water such as well water (ground water) is
used, this will cause deposits inside radiator or on cylinder head, and will cause engine overheat due to
poor flow of coolant.
When the unit is used in a cold region and possible freezing is expected, it is recommended to use LLC
(Antifreeze) for the coolant.
Adjust mixing ratio of LLC with water according to the temperature.
Use LLC within the range of its mixing ratio between 35 and 60%.
If LLC in the water exceeds more than 60%, it may decrease its antifreezing effect.

Follow the designated regulations to dispose of LLC (Antifreeze).
4.4.3
Fuel
Choose appropriate fuel
Be sure to use diesel fuel oil.
(Using other oil will cause low power output or damage the engine.)
As for fuel, use diesel fuel oil (having higher than 45 cetane number).
Use of diesel fuel oil having lower than 45 cetane number will cause inferior function to engine and,
what is worse, it will cause serious accident to the engine.

<Procedures>
① Pull out the engine oil level dipstick, and wipe it with a clean
MIN
cloth.
② Then, re-insert the dipstick fully and pull it out again. If the
gauge shows the oil level between MAX and MIN limits, it is
normal.
A000063
③ When the oil level is below its MIN, add engine oil. (See 5.5.1.)
While checking oil level, check also for contamination. If the oil is found dirty, contaminated, or
should be changed according to the periodic inspection list, change the oil.
4.5.2
Check Coolant Level
Taking off the radiator cap
Be sure to stop the machine first and then loosen the radiator
cap slowly, after the coolant water is sufficiently cooled and the
inner pressure is released.
If this procedure is neglected, its inner pressure can blow off the
cap, and steam jetting out of the radiator could cause scalding.
H990432
Check the coolant level in the reserve tank. If it is lower than
the limit, open the cap and replenish the coolant.
(Level must be kept above MIN mark)
If little coolant is left in the reserve tank, replenish the tank and

place.
Do not spark near the battery nor light a match, nor bring lit
cigarette and match close to the battery.
Do not check the battery by short-circuiting the positive and
negative terminals with a metallic piece.
Never operate the machine nor charge the batteries with the
battery liquid level being kept lower than the “LOWER” level.
Continuing operation at this lower level will cause deterioration
of such parts as pole plates etc., and also it may cause
explosion as well as reduction of battery life.
Add distilled water so that the liquid level may reach the middle
level between the “UPPER” and “LOWER” level without any
delay.
Do not charge the frozen battery. Otherwise it may explode. If
the battery is frozen, warm it up until the battery temperature
becomes 16°C to 30°C.
Battery electrolyte is dilute sulfuric acid.
In case of mishandling, it could cause skin burning.
Wear protective gloves and safety glasses when handling a
battery.
When such battery electrolyte contacts your clothes or skin,
wash it away with large amount of water immediately.
If the battery electrolyte gets into your eyes, wash it away
immediately with plenty of water and see a doctor at once,
because it is feared that eyesight might be lost.
Dispose of battery, observing local regulations.

7. Storage of the Unit
7.1
Preparation for Long-term Storage
When the unit is left unused or not operated longer than half a year (6 months), store it at the dry
place where no dust exists after the following treatments have been done to it.
Put the unit in a temporary cabin if it is stored outside. Avoid leaving the unit outside with a
sheet cover directly on the paint for a long time, or this will cause rust to the unit.
Perform the following treatments at least once every three months.
<Procedure>
① Discharge existing lubricant from the engine oil pan. Pour new lubricant in the engine to clean
its inside. After running it for a while, drain it again.
② Spread lubricant on each moving part.
③ Completely charge the battery and disconnect grounding wires. Remove the battery from the
unit, if possible, and store it in a dry place. (Charge the battery at least once every month.)
④ Discharge coolant and fuel from the unit.
⑤ Seal air-intake port of engine and other openings like the muffler with a vinyl sheet, packing
tape, etc., to prevent moisture and dust from getting in the unit.
⑥ Measure the insulation resistance of the generator, and make sure that it is more than 1MΩ.
(See 5.5.3)
⑦ Be sure to repair any trouble and maintain the unit so that it will be ready for the next
operation.
Stacking up box type machines
When stacking up the machines for storage, only two
units stacking is acceptable. The mass of the lower
machine should be larger than that of the upper one.
Select a leveled floor with sufficient strength.
Before stacking the machines up, check the machine for
deformation of bonnet, looseness or missing of bolts,
and other parts.
When stacking them, be sure to securely fix them as
shown in the figure so that the balanced weight is applied
to each squared lumber for preventing a sideslip or a
collapse.
Never operate the machines with stacking conditions.
It is very dangerous.
Machines stacked could fall down due to sideslip or
collaspse when an earthquake occurs. Therefore, safety
should be sufficiently considered for surroundings of
storage places.
