1.0 Safety Instructions
1.1 Safety Specification
Please read the manual carefully to familiarise yourself with the
generator and its components before operating. Familiarity with
the safe operating procedures of generators can help you avoid
accidents.
Do not use indoors
Do not use in wet or damp
conditions
Do not connect directly to
home/mains electricity
Do not smoke while filling with
fuel

7
Take care not to spill fuel
when refuelling
Stop the engine before
refuelling
Place inflammable materials at least 1m away from the unit

8
1.2 Special Information
Electrical equipment includes unexposed wires and plugs
The protecting breaker should be matched with generator
The application parameters and performance should be
totally matched if changing.
Ensure the unit is well grounded before using
Extension wires must meet the specification as follows:
Ø 4mm, length no more than 100 m

4.0 Control System
4.1 Low oil warning system (YELLOW)
The low engine oil protection system will
automatically stop the engine once the oil
level drops below the required minimum
amount. The Low oil indicator light will
remain illuminated until the generator is refilled with the correct
amount of oil.
If the engine oil warning light flashes for few seconds, it means
the oil capacity is insufficient. Refill the oil and restart the
engine.
4.2 Overload Indicating Light (RED)
When the overload indicator light is on, the
system has detected that the output of the
connected equipment has overloaded, causing
the inverter to overheat or AC voltage to rise.
The AC protector will kick-in and prevent the generator from
working to protect it and the connected equipment. When the AC
indicating light (GREEN) is off and the overload indicator light
(RED) is on, the generator will not stop working.
While the overload light is on, and the generator has no output,
please take following measures:
1. Turn off the connected electrical equipment and stop engine.
2. Reduce the total power of the connected equipment to within
the rated output range.

14
3. Check whether there is a foreign body blocking the air inlet
or if there is any abnormality with the relevant control parts
and eliminate if necessary.
4. After checking, press the voltage recovery button for 1-3
seconds and restart.
Notice: When using electrical equipment with a high start-up
current such as compressors or submersible pumps, the
overload indicating light may flash for few seconds however
this may not necessarily indicate the previously mentioned
faults. Overload, short circuit, overheating and low engine
speed can all prevent output. Eliminate the above reasons
until output is restored
4.3 AC Indicator Light (GREEN)
The AC indicating light will remain lit
throughout operation with stable output
4.4 ECO Switch
①“ON”
While the ECO switch is on position of “ON”,
the equipment will control the throttle speed
according to the connected load, which can
achieve better fuel consumption and low noise.
②“OFF”
While the ECO switch is in the “OFF” position, the engine will
run continuously at the rated speed (3600r/min) regardless of
whether the load is connected.
NOTICE: The switch must be set to “OFF” when connecting
any equipment requiring a high start-up current

15
4.5 Ground/Earth Terminal
The ground/earth terminal is designed to be connected to the
ground wire to prevent electric shock.
When electrical equipment is grounded, the generator must
also be grounded.
4.6 AC Breaker Protector Switch
The AC Breaker protector will automatically stop the generator
if an AC short circuit or overload occurs. If the breaker
protector is activated, please check that the connected
appliance does not exceed the rated load before resetting to
ON

5.0 Preparation
5.1 Fuel
Fuel is flammable and toxic. Please read the safety
instructions very carefully before attempting to refuel the
generator. (See Pages 6/7 for details.)
Do not overfill the tank with fuel otherwise it will
overflow when the generator gets hot
Once refuelling is complete, ensure the fuel filler cap
is replaced securely
Only use unleaded petrol, leaded fuel will damage the
internal parts of the engine
Fuel tank capacity: 12.50L
To avoid damageto the outer casing, immediately wipe up any
fuel spilled during refilling with a soft clean cloth
Fuel tank
cap

5.2 Engine Oil
The generator is shipped dry, without engine oil. Please do
not attempt to start it before adding the correct grade and
amount of oil.
1. Place the generator on a level surface
2. Turn the knob ①to “ON”, and pull down the oil
maintenance cover ②
3. Open the oil filler cap ③

18
4. Fill with the recommended grade and amount of oil,
replace and tighten the oil filler cap
5. Replace oil maintenance door and turn knob to
“OFF” position
5.3 Recoil Starter
Pull the starter handle up gently until resistance is felt, then
pull it firmly to start the engine

19
5.4 Fuel Tap
Fuel tap is a device that controls the flow of fuel from the
tank to the carburettor. Please ensure the 3 in 1 control
knob is set to the “OFF” position when not in use.

20
5.5 Choke Valve
The choke is designed to restrict the air flow to the
carburettor, providing a richer fuel mixture which enables
the engine to be started easily in cold conditions.
When starting from cold, select the "CHOKE" (start)
position on the 3 in 1 control knob.
Once running and engine is warm, set and leave the 3 in 1
control knob to the “RUN”position.
