1. SAFETY PRECAUTIONS
1.1: SAFETY LABELS
DANGER
This symbol refers to a hazardous or unsafe practice
which has the potential to result in personal injury or
product property damage.
WARNING
This symbol warns of immediate hazards which will
result in severe or lethal personal injury.
This symbol warns of hazards which can result in severe
or lethal personal injury.
CAUTION
1.2: OPERATIONS SAFETY
• Operate the generator according to instructions for safe
and dependable service.
• Always perform a pre-operation check before starting the
engine.
• Properly clean and maintain the equipment.
• Read the user manual carefully before operation. Other-
wise, it may result in personal injuries or equipment dam-
age.
• Never run the generator in an enclosed area, since the
exhaust emits poisonous carbon monoxide gas.
• Gasoline is a highly ammable and explosive liquid. Refuel
in a well ventilated area with the engine stopped.
• Be careful not to touch the exhaust system during opera-
tion because it can cause burns.
• Pay attention to the warning labels because the engine
exhaust system will become heated during operation and
remain hot immediately after the engine is stopped.
• When refueling the generator, keep it away from the ciga-

4.
EN
rettes, 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. Im-
proper connections may cause serious injuries to electrical
workers during power outage, and when the utility power is
restored, the generator may explode or cause res.
• Place the generator at least 3ft away from buildings or
other equipment during operation.
• Run the generator on a level surface. If the generator tilts,
fuel spillage may result.
• Know how to stop the generator quickly and understand
operation of all the controls. Never permit anyone to oper-
ate the generator without proper instructions.
• Keep children, pets and rotating parts away from the gen-
erator 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 generator is operat-
ing and shortly after the generator has been shut down
1.3: 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 inves-
tigate 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 run-
ning power of the generator, the generator should not be
used for more than 30 minutes.
• The connections from the generator to the household pow-
er supply should be done by professional electrical techni-
cians. Improper connections may lead to a re hazard or
damages to the generator set.
1.4: MAINTENANCE SAFETY
• After any maintenance is performed, wash your body im-
mediately using soap and clean water because repeated
exposure to lubricant may cause skin irritation.
• Do not clean the lter sponge with ammable uids like

5.
EN
gasoline because explosion may occur.
• Turn off the generator set before performing any mainte-
nance. Otherwise it can cause severe personal injury or
death
• 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.
1.5: 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 elec-
trical components on the control panel before each use.
Moisture can damage the generator and can lead to an
electric shock.

3. PRE-OPERATION INSPECTION
WARNING
Be sure to check the generator on a level surface with the
engine stopped
• Ensure the generator is on a level surface
•Engine Oil Inspection:
WARNING
Using non-detergent oil or 2-stroke engine oil could
shorten the generator’s life
1. Loosen the cover screws and remove the maintenance cover
(Refer to Fig. 3.0 for HY1000Si and Fig. 3.1 for HY2000Si)
2. Remove the oil ller cap and wipe the dipstick clean (Refer to
Fig. 3.2 for HY1000Si or HY2000Si)
Check the oil level by inserting the dipstick into the ller neck
without rotating it
3. If the level is low, ll to the upper limit of the oil ller neck with
the recommended oil
4. Reinstall the maintenance cover and tighten the cover screws

NOTICE
The Oil Alert System will automatically shut off the engine before
the oil level falls below the safe limit. However, to avoid the incon-
venience of an unexpected shutdown, it is still advisable to visually
inspect the oil level regularly.
Fuel level check:
1. Turn the engine start switch to STOP position
2. Open the fuel cap cover. Remove the fuel cap and check the fuel
level
3. Rell the fuel tank if the level is low. Refuel carefully to avoid

spilling fuel. Do not ll above the upper limit mark (Refer to Fig. 3.3)
-Gasoline is highly ammable and explosive. Keep the
engine away from heat, spark and open ame
-Refuel in a well-ventilated area with the engine stopped
-Handle fuel only outdoors
-Wipe up spills immediately
-Avoid getting dirt, dust or water in the fuel tank
-Never use an oil/gasoline mixture or dirty gasoline
-Don’t use fuel containing alcohol. Fuel system damage or
engine performance problems will result from the use of
fuels that contain alcohol
-Avoid repeated or prolonged contact with skin or breath-
ing of fuel vapor

Checktheairlter:
Never run the engine without the air lter. Rapid engine
wear will result from contaminants, such as dust and dirt,
being drawn through the carburetor, into the engine.
1. Loosen the cover screws, nuts and remove the maintenance
cover. Remove the air lter cover and the air lter sponge (Refer to
Fig. 3.4)
2. Observe the sponge for cleanliness
3. Clean sponge with soap and water or solvent. Squeeze dry
and then soak in clean engine oil. Squeeze out all excess oil and
reinstall.
4. Replace the sponge if it is damaged

4.1: STARTING THE GENERATING SET
NOTICE
-A hot engine will not start if there is too much gasoline in the cylin-
der. If this happens, wait for 5 to 10 minutes for the engine to cool
down before starting
-The engine will stop automatically when it is out of gasoline

-Do not allow the starter grip to snap back. Return it slowly
by hand
-Grasp the carrying handle rmly to prevent the generator
from falling over when pulling the starting grip
NOTICE
-If the engine stops and will not restart, check the engine oil level
before troubleshooting other areas
-Make sure the ECON switch is OFF before turning on the con-
nected device
Primer Bulb (For HY2000Si only)
The primer bulb is used for bringing small amounts of gasoline to
the throat opening of the carburetor. The problem is that sometimes
generator cannot start because the fuel cannot reach the carbure-
tor (Refer to Fig. 4.3)
Procedure for using the primer bulb
a) Set the choke rocker in the OPEN position
b) Push the primer bulb 7 to 10 times
c) Move the choke rocker to the CLOSE position and start the
engine
4.2: USING THE GENERATOR SET
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. Im-
proper connections may cause serious injuries to electrical
workers during power outage, and when the utility power is
restored, the generator may explode or cause res.
