SAFETY INFORMATION

This engine generator set has been designed and manufactured to 

allow safe, reliable performance. Poor maintenance, improper or 

careless use can result in potentially deadly hazards; from electrical 

shock, exhaust gas asphyxiation, or fire. Please read all safety 

instructions carefully before installation or use. Keep these instructions 

handy for future reference. Take special note and follow all warnings on 

the unit labels and in the manuals.

ANSI SAFETY DEFINITIONS

DANGER:

DANGER indicates an imminently hazardous situation which, if not 

avoided, will result in death or serious injury. This signal word is to be 

limited to the most extreme situations.

WARNING:

WARNING indicates a potentially hazardous situation which, if not 

avoided, could result in death or serious injury.

CAUTION:

CAUTION indicates a potentially hazardous situation which, if not 

avoided, may result in minor or moderate injury. It may also be used to 

alert against unsafe practices.

1. ELECTRICAL SHOCK -

The output voltage present in this equipment can cause fatal electric 

shock. This equipment must be operated by a responsible person.

 

A. Do not allow anyone to operate the generator without proper 

   instruction.

 

B. Guard against electric shock.

 

C. Avoid contact with live terminals or receptacles.

 

D. Use extreme care if operating this unit in rain or snow.

 

E. Use only three-pronged grounded receptacles and extension 

   cords.

 

F. Be sure the unit is properly grounded to an external ground rod 

 

  driven into the earth.

2. FIRE HAZARD - 

Gasoline and other fuels present a hazard of possible explosion and/

or fire.

 

 

A. Do not refuel when the engine is running or hot.

 

B. Keep fuel containers out of reach of children.

 

C. Do not smoke or use open flame near the generator set or fuel 

   tank.

 

D. Keep a fire extinguisher nearby and know its proper use.  

 

  Fire extinguishers rated ABC by NFPA are appropriate.

 

E. Store fuel only in an approved container, and only in a well 

 

  ventilated area.

 

F. Follow local codes for closeness to combustible material.

3. DEADLY EXHAUST GAS - 

Exhaust fumes from any internal combustion engine contain carbon 

monoxide, an invisible, odorless and deadly gas that must be mixed 

with fresh air.

 

A. Operate only in well ventilated areas.

 

B. Never operate indoors including attached garages

 

C. Never operate the unit in such a way as to allow exhaust gases  

 

  to seep back into closed rooms (i.e. through windows, walls, 

 

  floors).

4. NOISE HAZARD - 

Excessive noise is not only tiring, but continual exposure can lead to 

loss of hearing.

 

A. Use hearing protection when working around this equipment for 

 

  long periods of time.

 

B. Keep your neighbors in mind when using this equipment.

5. CLEANLINESS - 

Keep the generator and surrounding area clean.

 

A. Remove all grease, ice, snow or materials that create 

 

  slippery conditions around the unit.

 

B. Remove any rags or other materials that could create a  

 

  potential fire hazard.

 

C. Carefully clean up any gas or oil spills before starting the unit.

6. SERVICING EQUIPMENT -

All service, including the installation or replacement of service parts, 

should be performed only by a qualified technician.

 

A. Use only factory approved repair parts.

 

B. Do not work on this equipment when fatigued.

 

C. Never remove the protective guards, covers, or receptacle 

 

  panels while the engine is running.

 

D. Use extreme caution when working on electrical components. 

 

  High output voltage from this equipment can cause serious 

 

  injury or death.

 

E. Always avoid hot mufflers, exhaust manifolds, and engine parts. 

 

  They can cause severe burns instantly.

 

F. The use of the engine-generator set must comply with all  

 

  national, state, and local codes.

TESTING POLICY

Before any generator is shipped from the factory, it is fully checked 

for performance. The generator is loaded to its full capacity, and the 

voltage, current, and frequency are carefully checked.

Rated output of generator is based on engineering tests of typical units, 

and is subject to, and limited by, the temperature, altitude, fuel, and 

other conditions specified by the manufacturer of applicable engines.
