GENERAL SAFETY PROCEDURES
For any questions regarding the hazard and safety notices listed in this manual or on the product, please call (800)
232-1195 M-F 8-5 CST 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 batterybackup 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 an 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.

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 WEN® 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.

GENERATOR PREPARATION
USING THE GENERATOR FOR THE FIRST TIME
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 (800) 232-1195 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 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 50.7 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 (Figure 1) that matches
the starting temperature anticipated before the next oil changes.
Figure 1 - Engine Oil Temperature Recommendations
To add oil, follow these steps:
1. Make sure the generator is on a level surface. Tilting the generator to assist in filling will cause oil to flow into
engine areas and will cause damage. Keep generator level!
2. Open the door.
3. Remove the dipstick from the engine. (Figure 2)
4. Using a funnel or appropriate dispenser, add the correct amount of oil (50.7 fl.oz) into the crankcase. The
engine is equipped with a low oil sensor and will not start if the amount of oil is insufficient.
5. To check the oil level, wipe the dipstick with a clean rag. Insert the dipstick into the oil fill opening without
screwing it in. Remove the dipstick to check the oil mark.
6. Slowly add more oil and repeat step 4 until the oil mark reaches to the top of the dipstick (Figure 2). Do not
overfill the crankcase. The generator is equipped with a low-oil sensor and will not start if the amount of oil is
insufficient.
7. Check for oil leaks. Tighten dipstick firmly.

GENERATOR PREPARATION
Step 2 - ADD GASOLINE
WARNING: This generator may emit highly ammable and explosive gasoline vapors,
which can cause severe burns or even death if ignited. A nearby open ame can lead to
explosion even if not directly in contact with gasoline.
Use fresh (within 30 days from purchase), lead-free gasoline with a minimum of 87 octane rating. Do not mix oil
with gasoline.
Fuel tank capacity: 8 Gallons
To add gasoline, follow these steps:
1. Make sure the generator is on a level surface.
2. Unscrew fuel cap and set aside. NOTE: The fuel cap may be tight and hard to unscrew.
3. Slowly add unleaded gasoline to the fuel tank. Be careful not to overfill. The capacity of the fuel tank is 8 gallons.
NOTE: Do not fill the fuel tank to the very top. Gasoline will expand and spill over during use even with the fuel
cap in place.
4. Reinstall fuel cap and wipe clean any spilled gasoline with a dry cloth.
IMPORTANT:
• Never use an oil/gasoline mixture.
• Never use old gasoline.
• Avoid getting dirt or water into the fuel tank.
• Gasoline can age in the tank and make starting difficult. Never store generator for extended periods of time with
fuel in the tank or the carburetor.
• Turn the fuel cock off and drain the fuel from the carburetor.
Step 3 - GROUND THE GENERATOR
WARNING: Failure to properly ground the generator
can result in electrocution.
Ground the generator by tightening the grounding nut on the
front control panel against a grounding wire (Figure 3). A generally acceptable grounding wire is a No. 12 AWG (American Wire
Gauge) stranded copper wire. This grounding wire should be
connected at the other end to a copper, brass, or steel-grounding
rod that is driven into the earth. Wire and grounding rods are not
included in generator contents.
Grounding codes can vary by location. Contact a local electrician
to check the area codes.
