Safety Rules
Please read and understandthis manualthoroughlybefore operating your generator. Failure to
follow instructions could result in serious injury even death.
Exhaust gas contains poisonous carbon monoxide, which is harmful to the health. Never use the
generator set at the confined places or poor ventilated locations. If it’s necessary to run the
generator set, be sure to provide the adequateventilation.
Generator produces powerful voltage.
1. DO NOT touch bare wires or receptacles.
2. DO NOT use electrical cords that are worn, damaged or frayed.
3. DO NOT operate generator in wet condition or with wet hand.
4. DO NOT allow children or unqualifiedpersons to operate or service thegenerator.
5. DO NOT use a groundfault circuit interrupter (GFCI) in damp areas and areas containing
conductive material such as metal decking.
Use approved transfer equipmentto isolate generator from your electric utility and notify your utility
company before connectingyour generator to your power system.
Sparks can result in fire or electrical shock. Whenservicing the generator, disconnect the spark
plug wire and place it where it cannotcontact the plug. DO NOT check for spark with the plug
removed. Use only approved spark plug testers.

Safety Rules
Runningengines produceheat. Severe burnscan occur on contact. Combustiblematerial can catch
fire on contact.
Warning
!
1. Propane (LPG) and natural gas (NG) is highly flammable and explosive. Fire or explosion can
cause severe burns or death if the gas is ignited.
2. Before starting the generator, inspect your LPG tank and NG pipeline and valve for damage
or leaks, attach only approved tanks that have been properly filled by an approved station,
DO NOT light or smoke cigarette.
3. Replace the hose at the first sign of a leak or if age-cracking becomes apparent.
4. Whenstarting the generator DO NOT attempt to start a damagedgenerator, make certain
thatthe LPG tank, air filter, spark plug,fuel lines and exhaust system are properly in place,
make certain that the generator resting firmly on level ground.
5. Whenoperating the generator DO NOT move or tip the generator duringoperation, DO NOT
tip the generator or allow oil to spill.
6. Whentransportingor servicing thegenerator make certain that thegenerator is disconnected
and properly shut off, disconnectthe spark plug wire.
7. Whenstoring the generator store away from sparks, open flames, pilot lights, heat and other
sources of ignition.
Danger
!
1. Rapid retraction of the starter cord will pull hand and arm towards the engine faster than you
can let go. Unintentionalstartup can result in entanglement,traumaticamputationor
laceration. Broken bones, fractures, bruises or sprains could result in.
2. Whenstarting engine,pull the starter cord slowly until resistance is felt and then pull rapidly
to avoid kickback.
3. DO NOT start or stop the enginewith electrical devices pluggedin.
Warning
!
1. The battery contains acid. Acid is strongly corrosive.
2. DO NOT use, store or expose the battery in high temperature situations, as in the direct
sunlight,inside automobiles duringhot weather, directly in front of a heater, etc.
3. Be sure to turn off the equipmentafter use.
Warning
!
1. DO NOT touch hot surfaces.
2. Avoid contact hot exhaust gas.
3. Never touching the equipment until it’s cool.
4. Maintain at least 3 feet (about 1meter) of clearance on all sides to ensure adequate cooling.
5. Maintain at least 5 feet (about 1.5 meters) of clearance from combustiblematerials.

something for noise protection before running the generator set if it’s necessary, like as wearing
hearing protector and so on.
Caution
!
Exceeding the generator’s running capacity can damage the generator and/or electrical devices
connected to it.
Impropertreatment or use of thegenerator can damage it, shorten its life and void your warranty.
Use the generator only for intendeduse.
Caution
!
Use only genius AUTHORIZED SALES& SERVICEDEALER/DISTRIBUTOR parts or their
equivalent. The set of replacement which is not equivalent quality may damageyour generator.
Warning
!
1. DO NOT overload the generator.
2. Start the generator and allow the engine to stabilize before connecting electrical loads.
Connect electrical equipmentin the off position, and then turn them on for operation.
3. Turn electrical equipmentoff and disconnectbefore stoppingthe generator.
4. DO NOT tamperwith the speed governor.
5. DO NOT modify the generator in any way.

Start Engine
Notice
If your engine is starting, do an inspection on
the top cooling fan, and ensure it is operating.
Otherwise, you should stop the engine.
If the engine starts but does not run, make certain that the generator is on a flat, level surface. The
engine is equippedwith a low oil sensor that will prevent the enginefrom runningwhen the oil level
falls below a critical threshold.
Notice
1. This generator musthave at least 5 feet (about 1.5 meters) of clearance from combustiblematerial.
2. Leave at least 3 feet (about 1 meter) of clearance on all side of thegenerator to allow for adequate
cooling, maintenanceand servicing.
3. Place the generator in a well-ventilated area.
4. DO NOT place the generator near vents or intakes.
Caution
!
!
!
Step 1: Open gas fuel source (NG or LPG).
Step 2: Turn engine switch at ON position.
Step 3: Pushelectric start push buttonto
start engine. If the engine fails to start
with 5 seconds, release the buttonand
wait at least 5 seconds before attempting
to start engineagain.
Step 4: Turn circuit breaker at ON position.

Use Generator
1. Limit operation requiring maximum power to 30 minutes.
2. For continuousoperation, DO NOT exceed therated power. Recommendcontinuousrunning
time is not more than 8 hourswithout stop.
3. DO NOT exceed the current limit specified for any one receptacle.
4. Connection for emergency power to household circuit must be made by a qualified electrician
and must comply with all applicable laws and electrical codes.
5. Improperinstallation may result in personal injury or damageto equipmentor property.

exceed themaximum load. Substantialoverloading will switch off the circuit breaker. Lesser
overloading will not switch off the circuit breaker and will shorten the service life of the generator.
Caution
!
1. If the power outputreduces when in on-load status, adjust by closing the choke valve
gradually till the desired result.
2. Appliances / Equipmentsdrawing highercurrent should be switched on firstly. Wattagewould
differ amongst different brands. Hence, kindly check the same before use.
