Equipment), are certified to operate on regular unleaded gasoline, and may include the following
emission control systems: (EM) Engine Modifications and (TWC) Three-Way Catalyst (if so equipped).

SAFETY INFORMATION

Before operating this generator, read and observe all warnings, cautions, and instructions on the
generator and in this Owner’s Manual.

NOTE: The following safety information is not meant to cover all possible conditions and situations that

may occur. Read the entire Owner’s Manual for safety and operating instructions. Failure to follow

instructions and safety information could result in serious injury or death.

This safety alert symbol is used to identify safety information about hazards that can result in personal
injury.

A signal word (DANGER, WARNING, or CAUTION) is used with the alert symbol to
indicate the likelihood and the potential severity of injury. In addition, a hazard symbol may
be used to represent the type of hazard.

DANGER indicates a hazard, which, if not avoided, will result in death or serious injury.

WARNING indicates a hazard, which, if not avoided, could result in death or serious injury.

GENERAL SAFETY PROCEDURES

For any questions regarding the hazard and safety notices listed in this manual or on the product, please
call [phone] Mon-Fri 9-5 EST before using the generator.

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, crawlspaces, or other partly 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: The exhaust from this product contains chemicals known to the State of
California to cause cancer, birth defects, or other reproductive harm.

WARNING: 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

explosion even if it isn’t 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.

WARNING: This generator produces powerful voltage, which can result in electrocution.

• ALWAYS ground the generator before using it (see the “Ground the Generator” portion of the

“GENERATOR PREPARATION” section).

• Generator should only be plugged into electrical devices, either directly or with an extension

cord.

NEVER connect to a building electrical system without a qualified electrician. Such connections must
comply with local electrical laws and codes. Failure to comply can create a back-feed, which may result
in serious injury or death to utility workers.

• Use a ground fault circuit interrupter (GFCI) in highly conductive areas such as metal decking or

steel work. GFCIs are available in-line with some extension cords.

• Do not use in rainy conditions.

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

• Do not allow children or non-qualified persons to operate.

WARNING: This generator produces heat when running. Temperatures near exhaust can
exceed 1500F (650 C).

Do not touch hot surfaces. Pay attention to warning labels on the generator identifying hot parts of the
machine.

Allow generator to cool down after use before touching engine or areas of the generator that become hot
during use.

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

Only use generator for its intended purposes.

Operate only on dry, level surfaces.

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

Shut off and disconnect any malfunctioning devices from generator.

Do not exceed the wattage capacity of the generator by plugging in more electrical devices than the unit
can handle.
Do not turn on electrical devices until after they are connected to the generator.

Turn off all connected electrical devices before stopping the generator.

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

IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS – This manual contains important instructions for the PowerSmart®
3500W generator that should be followed during installation and maintenance of the generator.

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. Have damaged items
repaired or replaced as necessary. Do not use plugs or cords that show signs of damage such as broken or
cracked insulation.

For power outages, permanently installed stationary generators are better suited for providing backup
power to the home. Even a properly connected portable generator can become overloaded. This may
result in overheating or stressing of the components, possibly leading to a generator failure.

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 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.

PREPARATION

The following section describes steps necessary to prepare the generator for use. If after reading this
section, you are unsure about how to perform any of the steps please call [phone] Mon-Fri 9-5
EST for customer service. Failure to perform these steps properly can damage the generator or shorten its
life.

Step 1 - SETUP WHEEL KIT

WARNING: This generator is heavy. Assembly procedures may require lifting equipment or

two people.

ATTACH FRONT FOOT

To attach the feet to the generator, perform the following
steps:

1. Find a wooden block or a similarly sturdy item that is at

least three inches thick. Stack the end of the generator
with the recoil starter onto the wooden block.

2. Setup front foot as attached picture.

ATTACH WHEELS

To attach the wheels to the generator, perform
the following steps:

1. Rest the exhaust end of the generator on

the same wooden block used for attaching
the front foot.

2. Slide the wheel onto the axle.

3. Slide the wheel shaft with the cotter pin hole inward through the frame.

Secure using the cotter pin.

4. Repeat steps 2 and 3 for the other wheel.

Step 2 - ADD 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 fl. oz. For general use (above
40° F), we recommend 30W, 4-stroke engine oil.

ENGINE OIL RECOMMENDATIONS
Select good quality detergent oil bearing the American Petroleum Institute (API) service classifications
SJ, SL, or SM (synthetic oils may be used). Use the ASE viscosity grade of oil from the following chart
that matches the starting temperature anticipated before the next oil changes.
