SAFETY PRECAUTIONS

This generator is designed to give safe and dependable service if operated
according to instructions. Read and understand this manual carefully before
operating the generator, failure to follow instructions could result in serious injury
or death.

Engines give off carbon monoxide, an odorless, colorless, poison gas. Breath­ing carbon monoxide can cause nausea, fainting or death. Do not operate the
generator indoors or in a conned area and make sure the working environment
is well-ventilated.

The exhaust and mufer becomes very hot during operation and remains hot
for a while after stopping the engine. Make sure to read all warning labels. Be
careful not to touch the mufer while it is hot. Let the engine cool before storing
the generator indoors.

When storing gasoline or equipment with fuel in tank: Store away from furnaces,
stoves, water heaters or other appliances that have a pilot light or other ignition
source because they can ignite.

OPERATING INSTRUCTIONS

• Operate the generator according to instructions for safe and depend-

able service.

• Always perform a pre-operation inspection before starting the engine.

• Properly clean and maintain the equipment.

• Make sure to read and understand all warning labels.

• Gasoline is a highly ammable and explosive liquid. Make sure to

refuel in a well ventilated area with the engine stopped.

• When refuelling the generator, keep it away from cigarettes, open

ames, smoke, and/or sparks.

• Connections for standby power to a building’s electrical system must

be done by a qualied electrician and must comply with all applicable
laws and electrical codes. Improper connections may cause serious
injuries to workers during power outages. When the utility power is
restored, the generator may explode or cause res

• Place generator at least 1 m (3 ft.) away from buildings or other equip-

ment during operation.

AC SAFETY GUIDELINES

Before connecting the generator to an electrical device, or power cord:

• Make sure that everything is in right working order. Faulty devices or

power cords can lead to an electrical shock.

• Turn off the generator immediately if the device begins to operate

abnormally. Then disconnect the device and investigate the problem.

• Make sure that the electrical rating of the device does not exceed

that of the generator. If the power level of the device is between the
maximum output power and the running power of the generator, the
generator should not be used for more than 30 minutes.

• The connections from the generator to the household power supply

should be done by a professional electrical technician. Improper con­nections may lead to a re hazard or damages to the generator set.

MAINTENANCE SAFETY

• After any maintenance is performed, wash your body immediately us-

ing soap and clean water. Repeated exposure to lubricant may cause
skin irritation.

• Do not clean the lter sponge with ammable uids, such as gasoline,

or explosion may occur.

• Turn off the generator set before performing any maintenance. Other-

wise it can cause severe personal injury or death.

• Allow the generator set to cool down before performing any mainte-

nance.

• Always wear safety glasses when cleaning the generator with air.

• Do not clean the generator set with a pressure washer because it may

cause damage to the generator set.

• Before working with batteries, ventilate the area, wear safety glasses,

do not smoke and always disconnect the negative cable rst and
reconnect it last.

• Use rubber gloves when coming into contact with engine oil.

• Always stop the generator set before removing the oil ller cap.

• Only qualied maintenance personnel with knowledge of fuels,

electricity, and machinery hazards should perform maintenance
procedures.

NOTICE

The oil alert system is designed to prevent engine damage caused by
an insufcient amount of oil in the crankcase. Before the oil level in the
crankcase falls below a safe limit, the oil alert system will automatically
shut down the engine. If the oil alert system shuts down the engine, the
oil alert indicator will come on when you operate the starter and the
engine will not run. If this occurs, add engine oil.

FUEL LEVEL CHECK

1. Check fuel level display located on top of generator gas tank.

2. Rell the fuel tank if the level is low. Refuel carefully to avoid spilling
fuel. Do no ll above the upper limit mark (Refer to Fig.).

CAUTION

• Gasoline is highly ammable and explosive. Keep the engine

away from heat, spark the open ame.

• Refuel in a well-ventilated area with the engine stopped.

• Only handle fuel outdoors.

• Wipe up spills immediately.

• Avoid getting dirt, dust, or water in the fuel tank.

• Never use an oil/gasoline mixture or dirty gasoline.

• Do not use fuel containing alcohol. Fuel system damage or en-

gine performance problems will result from the use of fuels that
contain alcohol.
