terms of using the generator economically for a long-term and ensuring continuous safety of life and property. Required safety measures
should be taken in advance during the installation, usage and maintenance. Safe operating responsibility of the generator set belongs to
user who is using and maintaining it. Provided that instructions, methods and safety rules in this manual are complied with, risk of
accident will decrease.
Otherwise, unexpected defects and accidents which may result within serious injured and death of people and damage on the
equipment. Please have your generator used and maintained by well-trained people who issued or authorized persons in order to prevent
these occasions.
Please plan any part, machine or engine you are operating in a way to ensure easy access to every point. Take pre-safety
measures about how you can avoid from exposure to occasions like touching with rotating parts, burning and cut with sharp edges while
checking out the engine. Ensure that covers of turbo compressor driving shaft, pump shaft, fan belts and winglets among engine
components are fitted.
Never make any maintenance or repair while the generator set is operating. Turn off the generator and take all safety measures
before any maintenance initiated.
Never have unauthorized persons repaired and maintained, this will cause damage in your generator and also be out of from
scope of guarantee. We recommend you to use our authorized services providing 7/24 service.
This generator produces heat when running. Temperatures near exhaust can exceed 65 ºC (150 ºF).
1.2. ATTENTION! DON’T DO THE FOLLOWINGS:
Do not carry the generator on its side or in an inclined position during transportation. Oil or fuel may overflows into the air
filter and wets the filter, and the filter will not work if it does not absorb enough air. If this happens, remove the filter, wash it until the
oil or fuel is clean, dry it and put it back or replace it with a new one.
Don’t start the engine indoors. Exhaust gases are odorless and can be deadly as they contain carbon monoxide.
Do not insert your hands and feet into moving or rotating parts.
Do not store, pour or use gasoline near open flames or appliances such as stoves, water heaters or sparking devices.
Do not refuel in places such as poorly ventilated rooms. Do this in an open area.
Do not refuel while the engine is running. Allow the engine to cool for 20 minutes before filling the gas tank. Store fuel in
safe containers.
Do not remove the fuel tank cap while the engine is running.
Do not start the engine in the presence of gasoline odor or other explosive conditions.

2. PART: BEFORE STARTING:
Genpower Generators have been produced in international standards.
There is an oil level sensor in the generators to prevent damage to the engine in case of oil shortage. When the oil level falls
below a certain level, this sensor does not allow the generator to operate.
The oil capacity of the engine crankcase is 0.4 liters.
Verify engine oil level is correct.
Verify fuel level is correct.
Verify unit is secure on level ground, with proper clearance and is in a well ventilated area.
Use 20W50 oil which also used in gasoline vehicles as oil.
Each generator has a group identification plate. Serial number, qualifications, weights and manufacturing date of generators
are written on this group plate. Use this serial number in spare parts, repair claims, interviews and at your demands.
It is recommended to use high quality detergent oils classified as SE, SF, SD or SC. Detergent oils keep the engine clean and
prevent gumming and deposits. Nothing should be added to the recommended oil. The viscosity of the lubricating oil used should be
selected in accordance with the ambient temperature range in which the engine operates.
The exhaust system must be property maintained. Do not alter or modify the exhaust system as to render it unsafe or make it
noncompliant with local codes a /or standards failure to do so will result in death or serious injury.
Risk of fire. Do not use generator without spark arrestor installed. Failure to do so could result in death or serious injury.
Hot surfaces when operating machine do not touch hot surfaces keep machine away from combustibles during use. Hot
surfaces could result in severe burns or fire.

2.1 FILLING OIL:
The generator is shipped without oil in the engine. Add oil slowly and verify oil level often during filling process to ensure
overfilling does not occur.
Place generator on a level surface.
Clean area around oil fill and drain plug.
Use petroleum based oil for engine break-in before using synthetic oil.
Open the access panel, remove oil dipstick as shown in Figure 2.
Remove oil fill cap and wipe dipstick clean. See Figure 2.
To check oil level, remove funnel and insert dipstick into oil filler neck.
Insert funnel into oil fill opening. Add recommended engine oil as necessary. Climate determines proper engine oil viscosity.
See chart to select correct viscosity.
Remove dipstick and verify oil level is within safe operating range. See Figure-3.
Install oil fill cap /dipstick and hand tighten.
2.2 CHECKING THE OIL LEVEL:
Inspect engine oil level prior to each use or every 8 hours of operation.
Put the generator on a flat surface.
Clean area around oil fill, and oil drain plug.
Remove oil fill cap and wipe dipstick clean. See Figure 4.
To check oil level, insert dipstick into oil filler neck without screwing it in. See Figure 4.

2.3 GASOLINE RECOMMENDATIONS:
Your generator runs efficiently with all gasoline used for automotive.
It is recommended to use gasoline with an octane rating of at least 77. Do not mix oil with fuel.
Use clean, fresh and unleaded gasoline.
The capacity of the fuel tank is 1 gallon.
Do not fill the fuel tank to the very top. Gasoline will expand and spill over during use even with the fuel cap in place.
Purchase the amount of fuel to be used in the 30-day period. This ensures fuel freshness and the required fuel viscosity
according to the season.
When unleaded petrol is not available, leaded petrol can be used. Unleaded gasoline prolongs valve life as it reduces
combustion residues.
Do not use gasoline containing alcohol. If alcohol is to be used with the fuel, the gasoline should not contain more than 10%
ethanol and should be drained when the engine is not in use.
Do not open the fuel cap while the engine is running.
2.4 RECOMMENDATIONS FOR AN EFFICIENT PERFORMANCE:
Keep the generator flat while filling, storing and operating with oil and fuel.
Do not use pressurized starting fluid.
Use oil suitable for the temperature.
Do not start the engine with a low oil level.
Run the generator at no load (idle).
Use fresh fuel.
If the engine is cold, make sure to adjust the choke fully.
A hot engine requires less choke than a cold engine.

Figure-9 Shutdown Fault

GBG 15I GASOLINE GENERATORS USER AND MAINTENANCE MANUEL
13
The generator (stator winding) is isolated from the frame and from the AC receptacle ground pin.
Electrical devices that require a grounded receptacle pin connection will not function if the receptacle ground pin is not
functional.
4.2 KNOW GENERATOR LIMITS:
Overloading a generator can result in damage to the generator and connected electrical devices. Observe the following to
prevent overload;
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.
The rated wattage of lights can be taken from lights bulbs. The rated wattage of tools, appliances and motors can be found on
a data label or decal affixed to the device.
If the appliance, tool or motor does not give wattage, multiply volts times ampere rating to determine watts
(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 figure the running watts of all other connected loads.
Wattage Reference Guide is provided to assist in determining how many items the generator can operate at one time.
All figures are approximate. See data label on appliance for wattage requirements.
