P3200ie & P4300ie - 13 - 11-06

SAFETY PRECAUTIONS WHILE CHARGING

■

An explosive hydrogen gas is discharged
through vent holes in the battery during the
charging process. Do not allow spark or open
flame around the generator or battery during the
charging process.

■

Electrolyte fluid can burn eyes and clothing.
Be extremely careful to avoid contact. If injured,
wash the affected area immediately with large
quantities of water and consult a doctor for
treatment.

■

When charging a large capacity battery or
totally discharged battery, excessive current
may force the DC circuit breaker to turn off.
In such cases, use a battery charger to charge
a large battery with AC output.

■

Battery defects may cause the DC circuit
breaker to turn off.
Check the battery before replacing the DC
circuit breaker.

3. STOPPING THE GENERATOR

(a)

Turn off the power switch of the electric equipment
and unplug the cord from receptacle of the generator.

(b) Allow the engine about 3 minutes to cool down

at no load before stopping.

(c) Turn the engine switch to the position " " (CLOSE).

(See Fig. 4-e)
q " " (OPEN) w " " (CLOSE)

(d) [Electric starter model]

Turn the key switch to the " "(OFF) position.

4. OIL SENSOR (See Fig. 4-r)

q OIL SENSOR

(a) The oil sensor detects the fall in oil level in the

crankcase and automatically stops the engine
when the oil level falls below a predetermined level.

(b)

When engine has stopped automatically, switch off
generator's AC circuit breaker, and check the oil level.
Refill engine oil to the upper level as instructed
on page 5 and restart the engine.

(c) If the engine does not start by usual

starting

procedures, check the oil level.

Do not remove OIL SENSOR PROBE when
refilling with oil.
Remove oil filler cap on the opposite side
of carburetor.

CAUTION

Some appliances need a "surge" of energy when starting.
This means that the amount of electrical power

needed
to start the appliance may exceed the amount
needed to maintain its use.
Electrical appliances and tools normally come with
a label indicating voltage, cycles / Hz, amperage
(amps) and electrical power needed to run the
appliance or tool.
Check with your nearest dealer or service center
with questions regarding power surge of certain
appliances or power tools.

■

Electrical loads such as incandescent lamps
and hot plates require the same wattage to
start as is needed to maintain use.

■

Loads such as fluorescent lamps require 1.2
to 2 times the indicated wattage during start-up.

■

Loads for mercury lamps require 2 to 3 times
the indicated wattage during start-up.

■

Electrical motors require a large starting
current. Power requirements depend on the
type of motor and its use. Once enough
"surge" is attained to start the motor, the
appliance will require only 50% to 30% of the
wattage to continue running.

■

Most electrical tools require 1.2 to 3 times
their wattage for running under load during
use. For example, a 5000 watt generator can
power a 1800 to 4000 watt electrical tool.

■

Loads such as submersible pumps and air
compressors require a very large force to
start. They need 3 to 5 times the normal
running wattage in order to start.
For example, a 5000 watt generator would
only be able to drive a 1000 to 1700 watt pump.

5. WATTAGE INFORMATION

ON

START

OFF

P3200ie & P4300ie - 14 - 11-06

To determine the total wattage required to run a particular electrical appliance or tool, multiply the voltage
figure of the appliance/tool by the amperage (amps) figure of same. The voltage and amperage (amps)
information can be found on a name plate which is normally attached to electrical appliances and tools.

VOLTAGE DROP IN ELECTRIC EXTENSION CORDS

When a long electric extension cord is used to connect an appliance or tool to the generator, a certain
amount of voltage drop or loss occurs in the extension cord which reduces the effective voltage available for
the appliance or tool.
The chart below has been prepared to illustrate the approximate voltage loss when an extension

PERIODIC OPERATION AND
INSPECTION

When furnishing the generator as emergency

electric power source, periodic operation and

inspection are needed.

Fuel (gasoline) and engine oil will be deteriorated

with time, and this causes that the engine is

difficult to start and as the results improper

engine operation and fault.

Since the fuel (gasoline) will be deteriorated
with time, replace fuel (gasoline) with fresh
one periodically; once every three (3)
months is recommended.

CAUTION

(a) Check the fuel (gasoline), engine oil and air

cleaner.

(b) Start engine.

(c) With appliance such as lightings activated,

run the engine for over ten minutes.

(d) Check for the following items;

■

Proper engine running.

■

Adequate output and the indicator lamp
turned on properly.

■

The engine switch normally operated.

■

No leakage of engine oil and fuel (gasoline).

9. TRANSPORTING

When transporting the generator, make sure that

the fuel (gasoline) should be drained from the

tank.

(a) Turn the engine switch to the " " (CLOSE)

position.

(b) Drain the fuel from the tank.

■

To prevent fuel spillage due to the
vibration and impact, never transport
the generator with the fuel (gasoline)
filled in the tank.

■

Secure the tank cap thoroughly.

■

To avoid the risk of the gasoline
flammability, never leave the generator
in an area exposed to direct sunlight or
high temperatures for a long time.

■

Keep the fuel (gasoline) in the exclusive
gasoline storage tank made by steel
when transporting.

WARNING

(c) Secure the tank cap.

■

Do not place any heavy objects on the
generator.

■

Select and place the generator in the
proper position of the transport vehicle
so that the generator not be moved or
fallen down.
