then the engine stops automatically. Unless
you rell with oil, the engine will not start
again.
TIP: If the engine stalls or does not start,
turn the engine switch to “ON” and then
pull the recoil starter. If the oil warning light
ickers for a few seconds, the engine oil is
insufcient. Add oil and restart.
Overload Indicator Light (Red)
The overload indicator light comes on when
an overload of a connected electrical device
is detected, the inverter control unit over-
heats, or the AC output voltage rises. Then,
the AC protector will trip, stopping power
generation in order to protect the generator
and any connected electric devices. The AC
pilot light (Green) will go off and the over-
load indicator light (Red) will stay on, but the
engine will not stop running.
When the overload indicator 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
blockages are found remove.
4. After checking, restart the engine.
NOTE: The overload indicator light may
come on for a few seconds at rst when
using electric devices that require a large
starting current, such as a compressor or a

submergible pump. However, this is not a
malfunction.
AC Pilot Light (Green)
The AC pilot light comes on when the
engine starts and produces power.
Engine Smart Control
When the ESC switch is turned to “ON”, the
economy control unit controls the engine
speed according to the connected load. The
results mean better fuel consumption and
less noise.
When the ESC switch is turned to “OFF”,
the engine runs at the rated (3100 r/min)
Regardless of whether is a load connected
or not.
NOTE: The ESC must be turned to“OFF”
when using electric devices that require a
large starting current, such as a compressor
or a submergible pump.
DC Protector
The DC protector turns “OFF” automatically
when an electric device connected to the
generator is operating over peak wattage. To
operate the equipment again, switch the DC
protector button to “ON”.
NOTICE: Reduce the load of the connected
electric device below the specied rated
output of the generator if the DC protector
turns off. If the DC protector turns off again,
stop using device immediately and consult
your nearest GT POWER Dealer.
Ground (Earth) Terminal
The Ground (Earth) terminal (9) purpose is
to connect the generator frame to a ground-
ing point such as an earth stake to prevent
against electric shock from the generator
frame in the case of a short circuit or other
electrical malfunction of the generator or
the connected load. It is not required to be
connected for operation of the generator,
it is an additional safety feature. If in doubt
if grounding protection is required for your

Maintenance Schedule
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.
Generator maintenance consists of keeping
the unit clean and dry. Operate and store
the unit in a clean dry environment where it
will not be exposed to excessive dust, dirt,
moisture or any corrosive vapours. Cooling
air slots in the generator must not become
clogged with debris.
• Check for any foreign materials while
changing the engine oil and report to
repair agent if necessary
• Check the cleanliness of the generator
frequently and clean when dust, dirt, oil,
moisture or other foreign substances are
visible on its exterior surface.
CAUTION: Never insert any object or
tool through the air cooling slots, even
if the engine is not running.
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.
NOTE: If you are not familiar with
maintenance work, have a GT
POWER Service Dealer do it for safety.
WARNING: Stop the engine before
starting maintenance work.

Engine Oil Replacement
Avoid draining the engine oil immediately after
stopping the engine. The oil is hot and should
be handled with care to avoid burns.
1. Place the generator on a level surface and
warm up the engine for several minutes.
2. Remove the oil ller cap (1).
3. Place an oil pan under the engine, remove
the oil drain bolt (4) and drain the oil from
the oil tank.
4. Check oil ller cap (1), O-ring (2), Oil drain
bolt (4) and Oil ller cap packing (3).
Replace immediately if any are damaged.
5. Assemble oil drain bolt (4) and oil ller cap
packing (3).
6. Add oil till to a suitable level then tighten oil
ller cap (1).
NOTE: Do not tilt the generator
when adding engine oil. This could
result in overlling and damage to the
engine.
Air Filter
1. Remove air lter cover and foam element (1).
2. Wash the foam element in solvent and dry.
3. Add oil to foam element and squeeze out
any excess. Foam element should be wet
but not dripping to avoid damage.
4. Insert the foam element into the air lter
case.
NOTE: Be sure the foam element
sealing surface matches the air lter
cover so there is no leak. The engine
should never run without the air lter;
this will lead to piston and cylinder
wear.
5. Install the air lter case cover in its original
position.

Storage
Long term storage of your machine will require
some preventive procedures to guard against
deterioration.
Drain the Fuel
1. Turn the 3 in 1 switch to “OFF”.
2. Remove the fuel tank cap, remove the lter.
Extract the fuel from the fuel tank into an
approved gasoline container using a
commercially available hand siphon. Then,
install the fuel tank cap.
3. Fuel is highly ammable and poisonous.
Check “Safety Rules” (See page 4) carefully
wipe off spilled fuel immediately with a
clean, dry, soft cloth, since fuel may
deteriorate painted surfaces or plastic parts.
4. Start the engine and leave it to run until it
stops. The engine stops in approx. 20 mins.
Time by running out of fuel.
NOTE: Do not connect any electrical
devices. (Unloaded operation). Duration
of the running engine depends on the
amount of the fuel left in the tank.
5. Drain the fuel from the carburetor by
loosening the drain screw on the carburetor
oat chamber.
6. Turn the 3 in 1 switch to “OFF”.
7. Tighten the drain screw.

2. Turn the engine over several times using the
recoil starter (with 3 in 1 switch knob off) to
coat the cylinder walls with oil.
3. Pull the recoil starter until you feel
compression. (This prevents the cylinder and
valves from rusting).
4. Then stop pulling.
5. Clean the outside of engine and spray with an
anti-rust compound.
6. Store the generator in a dry, well-ventilated
place, with the cover placed over it.
