GENERATOR SAFETY WARNINGS

DANGER: CARBON MONOXIDE

Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monox­ide (CO). This is a poison gas you cannot see or smell. If you can smell the generator exhaust, you are
breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.

NEVER use a generator inside homes, garages, crawl spaces, or other partially enclosed areas. Deadly
levels of carbon monoxide can build up in these areas. Using a fan or opening windows and doors does
NOT supply enough fresh air. ONLY use a generator OUTSIDE and far away from windows, doors, and
vents. These openings can pull in generator exhaust.

Even if you use a generator correctly, CO may leak into the home. ALWAYS use a battery-powered or
battery-backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the generator has
been running, move to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.

WARNING: RISK OF EXPLOSION. HIGHLY FLAMMABLE: This generator may emit highly flam-

mable and explosive gasoline vapors, which can cause severe burns or even death, if ignited. A nearby
open flame can lead to explosion even if not directly in contact with gasoline.

• Do not operate near open flame.

• Do not smoke near generator.

• Always operate on a firm, level surface.

• Always turn generator off before refueling. Allow generator to cool for at least 2 minutes before re­moving fuel cap. Loosen cap slowly to relieve pressure in tank.

• Do not overfill fuel tank. Gasoline may expand during operation. Do not fill to the top of the tank. Allow
for expansion.

• Always check for spilled fuel before operating.

• Empty fuel tank before storing or transporting the generator.

• Before transporting, turn fuel valve to OFF and disconnect spark plug wire.

WARNING: If this generator is used as a supply for a BUILDING’S WIRING SYSTEM, the generator

MUST be installed by a qualified electrician and connected to a transfer switch as a separately derived
system in accordance with all applicable laws and electrical codes and the National Electrical Code,
NFPA 70. The generator shall be connected to a transfer switch that switches all conductors exclud­ing the equipment grounding conductor. The frame of the generator shall be connected to an approved
grounding electrode.

California Proposition 65 WARNING: This product contains chemicals and produces exhaust

known to the State of California to cause cancer, birth defects and other reproductive harm.

GENERATOR SAFETY WARNINGS

WARNING: Do not let comfort or familiarity with the product replace strict adherence to product

safety rules. Failure to follow the safety instructions may result in serious personal injury.

OPERATING ENVIRONMENT

1. Using a generator indoors can KILL YOU IN MINUTES. Only use a generator outside and far away from win­dows, doors and vents.

2. Do not operate near open flame or flammable materials. This generator may emit highly flammable and
explosive gasoline vapors, which can cause severe burns or even death if ignited. A nearby open flame can
lead to an explosion even if it isn’t directly in contact with gasoline.

3. Do not smoke near the generator.

4. Do not use the generator in rainy or wet conditions; doing so significantly increases the risk of electrical
shock.

5. Always operate the generator on a dry, firm, level surface.

6. Do not allow children or non-qualified persons to operate the generator.

7. Do not use or store LPG cylinder in a building, garage or enclosed area. Failure to do so will result in death
or serious injury. Liquid Petroleum Gas (LPG) is highly flammable and explosive. Flammable gas under pres­sure can cause a fire or explosion if ignited. Always keep the LPG cylinder in an upright position. The LPG
cylinder valve should be turned OFF (closed) when generator is not in use; failure to do so could result in death
or serious injury.

GENERATOR PREPARATION

1. Always ground the generator before using it to maximize safety (see “GROUND THE GENERATOR” section
on page 18).

2. Always make sure generator is turned OFF before filling the fuel tank. Do not overfill fuel tank, as gaso­line may expand during operation. Do not fill to the very top of the tank. Leave room for gasoline expansion.
Always check for spilled fuel before operating.

3. Do not use receptacles or cords that show signs of damage, such as broken or cracked insulation. If
any part of the generator or electrical device is broken, damaged, or defective, make sure it is repaired or
replaced before operation. Service should only be performed by a qualified technician.

4. Use a ground fault circuit interrupter (GFCI) in highly conductive areas such as metal decking or steel
work. Extension cords with in-line GFCIs are recommended for these operations to maximize safety.

5. NEVER connect the generator to a building’s electrical system without consulting a qualified electrician.
Such connections must comply with local electrical laws and codes. Failure to comply can create a back­feed, which may result in serious injury or death to utility workers.

GENERATOR SAFETY WARNINGS

GENERATOR OPERATION

1. Only use the generator for its intended purposes. Modifying or using the generator for operations for
which it was not designed may cause hazards and personal injury.

2. Do not touch bare wires or receptacles (outlets).

3. Do not exceed the wattage capacity of the generator by plugging in more electrical devices than the unit
can handle.

4. Allow generator to run for several minutes before connecting electrical devices.

5. Do not exceed the wattage capacity of the generator by plugging in more electrical devices than the unit
can handle (see “OPERATION” section).

6. Do not turn on electrical devices until after they are connected to the generator.

7. Generators vibrate in normal use. During and after the use of the generator, inspect both the generator
as well as extension and power supply cords for damage resulting from vibration.

8. Do not touch HOT PARTS. This generator produces heat when running. Temperatures near exhaust can
exceed 150º F (65º C). Allow generator to cool down after use before touching engine or areas of the gen­erator that become hot during use.

9. Turn off all connected electrical devices before stopping the generator.

10. Always turn generator off before refueling. Allow generator to cool for at least 2 minutes before remov­ing fuel cap. Loosen cap slowly to relieve pressure in tank.

11. Turn the engine switch to “OFF” position when the engine is not running.

12. Empty fuel tank before storing or transporting the generator. Do not store generator or gasoline near
furnaces, water heaters, or any other appliances that produce heat or have automatic ignitions. Store the
generator and fuel away from sparks, open flames, pilot lights, heat and other sources of ignition.

CAUTION: Misuse of this generator can damage it or shorten its lifespan.

TO MAXIMIZE THE LIFESPAN OF YOUR GENERATOR:

We recommend running your generator at least once a month for 20 to 30 minutes. Start the generator
according to the instructions and plug a small load in to make sure the outlet is producing electricity.

If you do not run it often, it will greatly shorten the generator’s lifespan and void the warranty.

The following section describes the necessary steps to prepare the generator for use. If you are unsure about
how to perform any of the steps please call [phone] M-F 8-5 CST for customer service. Failure to
perform these steps properly can damage the generator or shorten its life.

STEP 1 - ADD/CHECK OIL

The generator is shipped without oil. User must add the proper amount of oil before operating the generator
for the first time. The oil capacity of the engine crankcase is 37.2 fl. oz (1.1 L).

ENGINE OIL RECOMMENDATIONS - Select good quality detergent oil bearing the American Petro-

leum Institute (API) service classifications SJ, SL, or SM (synthetic oils may be used). Select the SAE
viscosity grade of oil that matches the expected operating temperature. For general use (above 40° F),
we recommend 30W engine oil.

• 30W engine oil for tempera­tures above 40°F.

• 10W-30 engine oil for temper­atures between 0°F - 40°F.

To add oil, follow these steps:

1. Place the generator on a level surface. Make sure the engine
is OFF before adding or checking oil.

CAUTION: Keep the generator level! Tilting the generator to

assist in filling will cause oil to flow into the wrong areas of
the engine and cause damage.

2. Unscrew the oil dipstick from the engine.

3. Using an oil funnel or appropriate dispenser, slowly add oil
into the oil fill (Fig. 2), being careful not to overfill the unit. Fill
the crankcase to the upper fill line so you can visually see the oil
coming halfway up the oil fill threads (Fig. 3).

• Synthetic 5W-30 engine oil for
all temperature ranges.
