This product contains or emits chemicals

 

 

known to the state of California to cause

 

cancer, birth defects or other reproductive harm.

Study these SAFETY RULES carefully before installing, operating, or servicing this equipment. Become familiar with this manual and with the unit. The generator can operate safely, efficiently, and reli- ably only if it is properly installed, operated, and maintained. Many accidents are caused by failing to follow simple and fundamental rules or precautions.

Generac cannot possibly anticipate every possible cir cumstance that might involve a hazard. The warn- ings in this manual, and on tags and decals affixed to the unit, are, therefore, not all-inclusive. If using a procedure, work method, or operating tech- nique that Generac does not specifically recommend, satisfy yourself that it is safe for others. Also make sure the procedure, work method, or operating tech- nique chosen does not render the generator unsafe.

Manual backgroundManual background DANGER

Despite the safe design of this generator,

!operating this equipment imprudently, neglect- ing its maintenance, or being careless can cause possible injury or death. Permit only responsi- ble and capable persons to operate and main- tain this equipment.

Parts of the generator are rotating and/or hot

!during operation. Exercise care near running generators.

Potentially lethal voltages are generated by these machines. Ensure all steps are taken to render the machine safe before attempting to work on the generator.

!GENERAL HAZARDS !

For safety reasons, Generac recommends that the installation, initial startup, and maintenance of this equipment be performed by a Generac Authorized Service Dealer.

The generator engine releases DEADLY carbon monoxide gas through its exhaust system. This dangerous gas, if breathed in sufficient concentra- tions, can cause unconsciousness or even death. Never operate the generator set with the vehicle inside any garage or other enclosed area. DO NOT OPERATE THE GENERATOR IF THE EXHAUST SYSTEM IS LEAKING OR HAS BEEN DAMAGED. SYMPTOMS OF CARBON MONOXIDE POISON- ING ARE (a) inability to think coherently, (b) nau- sea, (c) vomiting, (d) twitching muscles, (e) throb- bing temples, (f) dizziness, (g) headaches, (h) weakness, and (i) sleepiness. IF EXPERIENCING ANY OF THESE SYMPTOMS, MOVE INTO FRESH AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET MEDICAL HELP. Shut down the generator and do not operate it until it has been inspected and repaired.

Never sleep in the vehicle while the genset is run- ning unless the vehicle has a working carbon monoxide detector. The exhaust system must be installed in accordance with the genset installation manual. Make sure there is ample fresh air when operating the genset in a confined area.

The engine exhaust fumes contain carbon monox- ide, which can be DEADLY. This dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death. Thus, the exhaust system must be installed properly, in strict com- pliance with applicable codes and standards. Following installation, do nothing that might ren- der the system unsafe or in noncompliance with such codes and standards. The generator com- partment must be completely vapor-sealed from the vehicle interior. There must be no possibility of exhaust fumes entering the vehicle interior. Never operate this equipment with a leaking or defective exhaust system.

Keep hands, feet, clothing, etc., away from drive belts, fans, and other moving or hot parts. Never remove any drive belt or fan guard while the unit is operating.

Adequate, unobstructed flow of cooling and venti- lating air is critical to correct generator operation and is required to expel toxic fumes and fuel vapors from the generator compartment. Without sufficient cooling airflow, the engine/generator quickly overheats, which seriously damages the generator. Do not alter the installation or permit even partial blockage of ventilation provisions, as this can also seriously affect the safe operation of the generator.
