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 Owner’s Manual and with the unit. The gen- erator can operate safely, efficiently and reliably only if it is properly installed, operated and maintained. Many accidents are caused by failing to follow simple and fun- damental rules or precautions.

Generac cannot possibly anticipate every possible circumstance 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 technique Generac does not specifically recommend, satisfy your- self that it is safe for others. Also make sure the proce- dure, work method or operating technique chosen does not render the generator unsafe.

DANGER

Despite the safe design of this generator,

!operating this equipment imprudently, neglecting its maintenance or being careless can cause possi- ble injury or death. Permit only responsible and capable persons to operate or maintain this equipment.

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.

Parts of the generator are rotating and/or hot

!during operation. Exercise care near running gen- erators.

! GENERAL HAZARDS !

For safety reasons, Generac recommends that the installation, initial start-up and maintenance of this equipment is carried out by a Generac/Guardian Authorized Dealer.

Installation, operation, servicing and repair of this (and related) equipment must always comply with applicable codes, standards, laws and regulations. Adhere strictly to local, state and national electrical and building codes. Comply with regulations the Occupational Safety and Health Administration (OSHA) has established. Also, ensure that the gener- ator is installed, operated and serviced in accordance with the manufacturer’s instructions and recommen- dations. Following installation, do not do anything that might render the unit unsafe or in noncompli- ance with the aforementioned codes, standards, laws and regulations.

The engine exhaust fumes contain carbon monoxide, which can be DEADLY. This dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death. For that reason, ade- quate ventilation must be provided. Exhaust gases must be piped safely away from any building or enclosure that houses the generator to an area where people, animals, etc., will not be harmed. This exhaust system must be installed properly, in strict compliance with applicable codes and standards.

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 ventilating air is critical in any room or building housing the gen- erator to prevent buildup of explosive gases and to ensure correct generator operation. Do not alter the installation or permit even partial blockage of ventila- tion provisions, as this can seriously affect safe oper- ation of the generator.

Keep the area around the generator clean and unclut- tered. Remove any materials that could become haz- ardous.

When working on this equipment, remain alert at all times. Never work on the equipment when physically or mentally fatigued.
