Parameter Display (14)
The control panel is equipped with a
parameter display meter that shows voltage,
frequency and hour run time. Press the
mode change button (13) on the meter to
cycle through each value.
The meter functions are as follows:
- Output voltage in volts (V)
- Output current in amps (A)
- Output power in watts (P)
- Output frequency in hertz (Hz)
- Total operating hours (H)
LED Indicators
The LED Indicators assist in communicating
proper and improper functions of the unit. Low Oil Alarm (12)
When the engine oil falls below the required
level the Low Oil Alarm will come on and the
engine will stop automatically. The engine will
not restart until oil is added to the unit to bring
it up to the appropriate level.
Output Indicator (11)
The AC Output Indicator (pilot light) comes
on when the engine starts and produces
power.
Overload Alarm (10)
The Overload Alarm comes on when a con-
nected device requires more power than the
generator is able to produce, the inverter con-
trol unit overheats, or the AC output voltage
rises above rated values. The Output Indica-
tor (Green) will go off and the Overload Alarm
(Red) will stay on, but the engine will continue
to run.
When the Overload Alarm light comes on and
power generation stops, proceed as follows:
1. Turn off any connected electric devices
and stop the engine.
2. Reduce the total wattage of connected
electric devices within the rated output.
3. Check for blockages in the cooling air inlet
and around the control unit. If any block-
ages are found remove them.
4. After checking, restart the engine.
NOTE: The Overload Alarm may come
on for a few seconds when rst using
CAUTION!
Generator should only be operated on
a level surface. DO NOT operate the
generator on loose ground or obvious
inclines. The low oil shutdown feature
may be prematurely activated in these
cases causing the engine to not start.

The Earth terminal is used to earth the gen-
erator when earthed electrical devices are
being used. Consult an electrician for local
earthing regulations.
AC (3) and DC (5) Reset
Circuit Breakers)
The Circuit Breakers turn the generator
“OFF” automatically when an electrical de-
vice connected to the generator is operating
above the rated current. To use this equip-
ment again, turn on the Circuit Breaker by
pressing in its button to “ON”. If Circuit Break-
er cuts power out again, reduce the load of
the connected electric device below the
specied rated output of the generator and
press button in to “ON” again.

to cut out, stop using the device imme-
diately and consult your local author-
ised Powertec Service Provider.
according to the connected electrical load.
The results are better fuel consumption and
less noise.
When the switch is in the “OFF” position the
engine runs at 3600rpm regardless of wheth-
er there is a load connected or not.
NOTE: The ECO switch must be
turned to “OFF” when using electrical
devices that require a large starting
current, such as a compressor or a
submergible pump.
ECO Mode Switch (8)
When the ECO switch is in the “ON” position
the smart throttle controls the engine speed

NOTE: Remember that many types
of equipment need extra consump-
tion for start up. Equipment that uses
an engine such as compressors, wa-
ter pumps, circular saws etc. can con-
sume up to 3 times more power for
start up. For example a 1000W water
pump will need 3000W to start up,
therefore a generator 3000W or more
would be required.

• Place generator on a at, level surface.
• Remove oil cap and dipstick. Wipe
dipstick clean.
• Slowly ll oil into engine through the oil
lter until it reaches the full mark on the
dipstick.
• Stop lling occasionally to check oil level.
Be careful to not overll.
• Install oil ll cap and fasten the cap
properly.
• Check engine oil level before starting
each time thereafter.
NOTE: Never use old, dirty or bad
oils. Do not use oil if you don’t know
it’s grade or quality. Do not mix
different types of oils.
Adding Fuel
DANGER! Never ll tank indoors.
Never ll fuel tank when engine is
running or hot. Turn generator engine
OFF and allow engine to cool entirely
before lling fuel tank. Avoid spilling
gasoline on HOT engine. Keep fuel
away from sparks, open ames,
pilot lights, heat, and other ignition
sources. DO NOT light a cigarette
or smoke when lling the fuel tank.
Fuel is highly FLAMMABLE and its
vapours are EXPLOSIVE.
NOTE: The battery supplied is NOT
covered under warranty. Batteries
have limited lifespans and should be
replaced when required by a battery
with the same specications.
Adding Engine Oil
Please add correct oil before starting the
generator.
Above 5oC - use SAE 30
Between 5oC to -15oC - use 10W-30
Oil Capacity - GT3800Ei - 600ml
- GT4500Ei - 1L
recommended oil. This could result in
an engine failure.
Preparation before
Operating
Battery Connection
The battery supplied has the negative
terminal disconnected. Before connecting
check that the engine switch is in the ‘OFF’
position. Connect the negative wire using
the wingnut supplied.
NOTE: Improper treatment of
generator could damage it and
shorten its life. DO NOT attempt
crank or start the engine before it
has been properly serviced with the

• Use only regular UNLEADED gasoline.
Do not use any fuel blends with ethanol or
methanol.
• Do not mix oil with fuel.
• Avoid dirt and water entering the fuel tank.
• Install fuel cap and wipe up any spilled
gasoline.
CAUTION! Do not overll the fuel
tank. Allow space for fuel expansion.
NOTE: It is important to prevent gum
deposits from forming in fuel system
parts such as the carburetor, fuel hose
or tank during storage. Alcohol-blended
fuels (called gasohol), ethanol or
methanol) can attract moisture, which
leads to separation and formation of
acids during storage. Acidic gas can
damage the fuel system should be
emptied before storage for 30 days
or longer. See the “Storage” section.
Never use engine or carburetor cleaner
products in the fuel tank as permanent
damage may occur.
• Remove the fuel cap, turning counter
clockwise.
• Fill the tank with regular unleaded gaso-
line without exceeding the maximum level.
• Approximate capacity of fuel tank is 10L.
Fuel gauge indicates fuel level.
Earthing the Generator
Proper earthing (grounding) of the generator
will help prevent electrical shock in the event
of earth fault condition in the generator or in
connected electrical devices. Proper earthing
also helps dissipate static electricity, which
often builds up in un-earthed devices. Contact
an electrician for local earthing regulations.
IF the fuel tank is overlled, fuel can
overow onto a HOT engine and
cause FIRE or EXPLOSION. If fuel
spills, wait until it evaporates before
starting engine.
Check fuel lines, tank, cap and t-
tings frequently for cracks or leaks.
Replace if necessary.

plugged into the receptacles and
devices turned on.
• Turn fuel valve to “ON” position.
• Turn key ignition switch to “ON” and then to
“START”.release once engine has started
Unplug all electrical loads from the unit’s
receptacles before starting the engine.
Make sure the unit is in a level position.
• Turn choke to “ON” position.
NOTE: It may not be necessary to
use the choke if the engine has been
shut down and is warm.
NOTE: If engine does not start
up within 3 to 4 seconds, release
key ignition and wait for a few
seconds before trying again to avoid
overheating the starting motor.
• Once started, move the choke lever slowly
completely over to the “ON” position.
During the rst startup of the machine, the
battery’s charge may be low if stored for too
long. If the charge is not sufcient, start the
generator manually with the recoil start

device. Oil must be checked and at
proper level for engine to start and run.
WARNING! Exhaust heat/ gases could
ignite combustible, structures or damage
fuel tank causing a re, resulting in death,
serious injury and/or property damage.
Contact with mufer area could cause
burn resulting in serious injury. DO NOT
touch hot parts and AVOID hot exhaust
gases.Allow equipment to cool before
touching.
• Keep at least 150cm of clearance on all
sides of generator including overhead.
• When engine starts, move choke lever
to 1/2 “CHOKE” position till engine runs
smoothly and then fully into “RUN”
position. If engine falters, choke back to
1/2 “CHOKE” position till engine running
smoothly and then fully into “RUN”
position again. If battery is unavailable,
use manual starting instructions.
• If engine is choking and running move
choke lever to the “CHOKE” position and
repeat starting instructions.
WARNING! Starter cord kickback
(rapid retraction) will pull hand and arm
toward engine faster than you can let
go which could cause broken bones,
fractures, bruises, or sprains resulting
in serious injury. When starting engine,
pull cord slowly until resistance is felt
and then pull rapidly to avoid kickback.
Never start or stop engine with
electrical devices plugged in and
turned on.
• If engine fails to start after 3 pulls, or if
unit shut down during operation, make
sure unit is on a level surface and check
for proper oil level in crankcase. This
unit is equipped with a low oil protection
• Replacement parts must be the same
and installed in the same position as the
original parts
NOTE: Do not overload the generator.
Also,do not overload individual
panel receptacles. These outlets are
protected against overload with push-
to-reset-type circuit breakers.
If amperage rating of any circuit
breaker is exceeded, that breaker
opens and electrical output to that
receptacle is lost.
Connecting Electrical Loads
• Add up the total wattage of all electrical
devices to be connected at one time.
This total should NOT be greater than
the generator’s wattage capacity.
NOTE: The rated wattage of lights
can be taken from light bulbs. The
rated wattage of tools, appliances and
motors can usually be found on a data
label or decal afxed to the devices.
If the appliance, tool or motor does
not give wattage, multiply volts times
ampere rating to determine watts
• For recoil start, rmly grasp the recoil
handle and pull slowly until increased
resistance is felt. Pull rapidly up and away.
Recoil Start

(volts× amps = watts). Some electric
motors, such as induction types,
require about three times more watts
of power for starting than for running.
This surge of power lasts only a few
seconds when starting such motors.
Make sure to allow for high starting
wattage when selecting electrical
devices to connect to the generator:
• Figure the watts needed to start the
largest motor.
• Add to that gure the running watts of
all other connected loads. The wattage
reference guide on page 13 is provided
to assist in determining how many items
the generator can operate at one time.
Stopping The Engine
To stop the engine in an emergency, turn the
engine switch off by pressing to the “OFF”
position.
• For norrmal engine shutdown shut off
all loads then unplug the electrical loads
from generator panel receptacles. Never
start or stop the engine with electrical
devices plugged in and turned on.
• Let engine run at no-load for several
minutes to stabilise the internal
temperatures of engine and generator.
• Move ON/OFF switch to OFF position.
• Close fuel valve.
Low Oil Level Shutdown System
The engine is equipped with a low oil level
sensor that shuts down the engine auto-
matically when the oil level drops below a
specied level.
• If the engine shuts down by itself and
the fuel tank has enough gasoline,
check engine oil level. See page 11 for
more info.
NOTE: Start generator and let engine
stabilise before connecting electri-
cal loads. Connect electrical loads in
OFF position then turn ON for opera-
tion.Turn electrical loads OFF and
disconnect from generator before
stopping generator.
• Let engine run till stable and warm up for
a few minutes after starting.
• Plug in and turn on the electrical loads.
NOTE: Overloading a generator in
excess of its rated wattage capacity
can result in damage to the generator
and to connected electrical devices.

17
NOTE: DO NOT use a garden hose
to clean generator. Water can enter
the engine fuel system and cause
problems. In addition, if water enters
the generator though cooling air slots,
some water will be retained in voids
and crevices of the rotor and stator
winding insulation. Water and dirt build-
up on the generator internal windings
will eventually decrease the insulation
resistance of these windings.

To Clean the Generator
• Use a damp cloth to wipe exterior
surfaces.
• A soft, bristle brush may be used to
remove dirt, oil etc.
• A vacuum cleaner may be used to pick up
loose dirt and debris.
• Low pressure air (not to exceed 25psi)
may be used to blow away dirt. Check
cooling air slots and openings on the
generator. These openings must be kept
clean and unobstructed.

General Recommendations
The warranty of the generator does not
cover items that have been subjected to
operator abuse or negligence. To receive full
value from the warranty, the operator must
maintain the generator as instructed in this
manual.
Some adjustments will need to be made
periodically to properly maintain the
generator.
NOTE: Perform maintenance more fre-
quently when the generator is used in
places with a lot of dust, high tempera-
ture or heavy load.
While maintaining the generator you
should follow the service interval guide
above, using the time interval which
comes rst.
If you have missed the scheduled time
on the previous page to maintain your
engine, do it as soon as possible.
WARNING! Stop the engine before ser-
vicing. Place engine on a level surface
and remove spark plug cap to prevent
engine from starting.
Do not operate engine in a poorly ven-
tilated room or other enclosed area. Be
sure to keep good ventilation in working
area. The exhaust from engine may
contain poisonous CO, inhalation can
cause shock, unconsciousness and
even death.
NOTE: Lack of compliance with main-
tenance services will shorten the life of
the generator and may produce malfunc-
tions which are not covered by warranty.
Changing the Oil
• Keep the engine running for 5 to 10 min-
utes so the oil is heated, making it easier
to drain completely.
• Turn off generator.
• Place an appropriate container under the
oil draining hole to collect the used oil.
• Unscrew the oil drain screw by turning
anti-clockwise.
• Release the oil plug.
• Turn the engine by gently pulling the recoil
start which will dislodge oil from the mov-
ing parts of the engine.
• Drain oil into container.
• Once oil has drained, place the drain
screw and joint back and tighten
• Clean any spilt oil.
• Rell with recommended oil to the maxi-
mum level on the dipstick. See page 11
for more information.
RECOMMENDED OIL: SAE10W30

Air Filter Maintenance
NOTE: A dirty air lter will restrict the air
ow in the carburetor, which may cause
incorrect combustion, resulting in seri-
ous problems for the engine. Clean the
air lter regularly according to the main-
tenance plan in thi manual and more fre-
quently in dusty areas.
NOTE: Never start the generator without
the air lter as it may cause permament
damage.
NOTE: DO NOT use low ash point fuel
or solvents when cleaning the air lter.
They are ammable and explosive un-
der certain conditions.
• Loosen and remove the air lter cover-
screw (C).
• Take out the lter element (B).
• Clean the lter in a soap and water solu-
tion (E). Allow it to dry completely.
• Dip the dry lter in oil (F), the same type
as used in the generator engine.
• Squeeze out excess oil (G). Generator
will produce smoke from exhaust if not
wrung out properly)
• Install lter element in the lter box, close
cover and screw down.
EFG
Spark Plug Maintenance
RECOMMENDED SPARK PLUG: TORCH
F6RTC, NGK BP7ES, BOSCH WR3C
• Unplug the spark plug cap by pulling out-
ward (B).
• Using a spark plug spanner extract the
sparkplug by unscrewing from the engine
anti-clockwise (A).
• Inspect the spark plug visually. Replace
with a new one if cracked or chipped.
Clean electrode with a ne wire brush.
• Measure electrode distance with a gauge
and, if necessary, adjusted to specica-
tion.

20
• Install spark plug with hands and then
with spanner for nal tightening, replace
spark plug cap and screws.
NOTE: The spark plug must be tight-
ened rmly. A loose spark plug may
overheat and even damage the en-
gine. Similarly an over-tightened spark
plug may damage the spark plug
and the engine cylinder head thread.
Fuel Filter Maintenance
WARNING! Gasoline is ammable
and explosive. DO NOT perform this
maintenance while smoking or near
an open ame.
• Check fuel tank is empty. See page 11 for
emptying fuel tank.
• Using a spanner, unscrew fuel valve,
turning anti-clockwise.
• Remove fuel valve and check lter.
• Clean all residue from lter. Replace lter
if necessary.
• Re-assemble.
Spark Arrester Maintenance
• Allow generator to cool completely.
• Remove the xing screws.
• Clean carbon deposits carefully with a
brush.
• Re-install the spark arrester.
Transportation
& Storage
Transportation
In order to avoid fuel spillage during
transportation, always keep the fuel valve in
the “OFF” position. Fasten the machine so
it can’t move. Empty fuel from the generator
if transporting on a bumpy road or cross
country.
NOTE: Never place the machine on its
side or facing down during trransporta-
tion. Keep upright at all times.
WARNING! DO NOT use the genera-
tor whilst transporting.
DANGER! DO NOT leave genera-
tor in a parked vehicle in the sun. An
excessive rise in temperature could
evaporate the fuel and cause an
explosion.
Storage
Fuel loses it’s properties when stagnant,
from sitting for too long. Residues can clog
up the carburetor, preventing start-up. If
the generator is not going to be used for a
period of time (2 to 3 months or more) it is
important to drain the fuel from the tank, to
avoid future starting problems.
