GEN4000DF-SS 4000 Surge Watt / 3500 Running Watt Portable Dual Fuel LPG Liquid Propane Gas & Gasoline Generator Manual 

 

 

Notice Regarding Emissions: 

Engines certified to comply with U.S. EPA emission regulations for SORE (Small Off Road Equipment) are certified to operate on  
regular unleaded gasoline and may include the following emission control systems: Three-Way Catalyst (TWC) (if equipped), and Engine 

Modifications (EM). 

 
IMPORTANT SAFETY INSTRUCTIONS – SAVE THESE INSTRUCTIONS 

STOP!

 

Before using this generator and if you have any questions regarding the hazard and safety notices listed in this manual and/or on 
this generator, call 1-866-460-9436, Monday - Friday, 8 AM - 4 PM Central Time. 

 

                                                                        

 

Carbon Monoxide Gas:

 

When in operation, the exhaust from this generator contains poisonous carbon monoxide gas. Carbon 

monoxide gas is both odorless and colorless AND may be present even if you do not see or smell gas. Breathing this poison gas can 
lead to headaches, dizziness, drowsiness, loss of consciousness and eventually death.

 

• Use this generator ONLY outdoors in non-confined areas. 
• Keep at least several feet of clearance on all sides to allow proper ventilation for this generator. 
 

                                                                          

 

Propane (LPG):

 

This generator may emit highly flammable and explosive vapors, which can cause severe burns or even death. A 

nearby open flame can lead to an explosion even if not directly in contact the fuel. 

• Do not operate this generator near open flame. 

• Always operate this generator on a firm, level surface. 

This fuel is highly flammable and explosive. Handling fuel can result in serious injury or burns.

 

• Before starting the generator, inspect your LPG tank valve for damage or leaks, attach only approved tanks that have been properly filled by 
an approved station. DO NOT light or smoke cigarettes.  
• Replace the hose at the first sign of a leak or if age-cracking becomes apparent.

 

• Always handle propane fuel and generator outdoors. 

• Before transporting, turn the fuel valve to the "off" position and disconnect the spark plug. 
 

                                                                      

 

Powerful Voltage:

 

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

 

• ALWAYS ground this generator before using it. (See “Ground the Generator” section in this manual). 

• Only electrical devices should be plugged into this generator, either directly or with an extension cord. NEVER connect a building electrical 
system to this generator without a qualified electrician. 

Doing so voids your warranty. 

Such connections must isolate generator power from 

utility power and comply with local electrical laws and codes. Failure to comply can create a back feed into utility lines creating an electrocution 
hazard, which may result in serious injury or death to utility workers. Such a back feed may cause this generator to explode, burn and create 
fires when utility power is restored. 
• Do not use this generator in wet conditions (rain, snow, active sprinkler system, wet hands, etc.). Always keep this generator dry and operate it 

with dry hands. 
• Do not touch bare wires or outlets (receptacles). 
• Do not allow children or non-qualified persons to operate this generator. 
  

                                                                      

 

High Temperatures:

 

This generator produces heat when in operation. Temperatures near the exhaust can exceed 150 Degrees 

Fahrenheit (65 Degrees Celsius).

 

• Do not touch hot surfaces. Observe all warning placards on this generator denoting hot surfaces. 
• Allow this generator to cool for several minutes after use before touching the engine, muffler or other areas that are hot during operation and 
before storing indoors. 
• Hot exhaust may ignite some materials. Keep flammable materials away from this generator. 

• Keep at least several feet of clearance on all sides of this generator during operation. Do not enclose this generator in any structure. 
 

                                                                                 

 

Usage:

 

Avoid the use of extension cords if possible. 

If you choose to use them, be sure they are sized adequately to handle the flow of 

electricity. An undersized cord can overheat, short out and cause a fire.
