SAFETY
1.1 - Operation Safety
• Always perform a pre-operation check before starting the engine.
• Properly clean and maintain the equipment.
• Operate the generator according to instructions for safe and dependable
service.
• Read user manual carefully before operating this product! Failure to do
so may result in serious harm to the user and to the equipment.
• Before operating the generator, read the user manual carefully.
Otherwise, it may result in personal injuries or equipment damage.
• Never run the generator in an enclosed area to avoid harm from exhaust
emissions of a poisonous carbon monoxide gas.
• Be careful not to touch the exhaust system, compressor pump or
discharge tubing during operation due to risk of burns.
• Pay attention to the warning labels. The engine exhaust system will
become heated during operation and remain hot immediately after the
engine is stopped.
• Gasoline is a highly ammable and explosive liquid. Refuel in a well
ventilated area with the engine stopped.
• When refueling 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 electrical workers during a power outage, and when the utility power
is restored, the generator may explode or cause res.
• Place the generator at least 3 feet away from buildings or other
equipment during operation.
• Run the generator on a level surface. Tilting the generator may result in
fuel spills.

9
• Know how to stop the generator quickly and understand operation of
all the controls. Never permit anyone to operate the generator without
proper instructions.
• Keep children, pets and machinery with rotating parts away during
operation.
• Do not operate the generator in rain or snow.
• Do not allow any moisture to come in contact with the generator.
• Do not touch the spark plug while the engine is operating or shortly after
the engine has been shut down
1.2 - AC Safety Guidelines
Before connecting the generator to an electrical device or power cord:
• Make sure that everything is in proper 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 professional electrical technicians. Improper
connections may lead to a re hazard or damages to the generator set.
1.3 - Maintenance Safety
• After any maintenance is performed, wash immediately using soap and
clean water because repeated exposure to lubricant may cause skin
irritation.
• Do not clean the lter element with ammable liquids like gasoline
because an explosion may occur.
• Turn off the engine before performing any maintenance. Otherwise it can
cause severe personal injury or death.

10
• Allow the generator set to cool down before performing any
maintenance.
• Always wear safety glasses when cleaning the generator set with air.
• Do not clean the generator set with a pressure washer because it can
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.
1.4 - Other Safety Hazards
• To avoid breathing in poisonous carbon monoxide from the exhaust
gases, adequate ventilation should be provided if the generator set is
running in a partially enclosed space.
• If the generator set is stored outdoors, check all the electrical
components on the control panel before each use. Moisture can
damage the generator and can lead to an electric shock.
