WARNING:

!

 

 

 

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 Owner’s Manual and with the unit. The genera- tor can operate safely, efficiently and reliably only if it is properly installed, operated and maintained. Many acci- dents are caused by failing to follow simple and funda- mental rules or precautions.

Generac cannot possibly anticipate every possible cirumstance 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 pro- cedure, work method or operating technique that 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 possible injury or death. Permit only responsible and capable persons to install, operate or main- tain 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 this equipment be installed, serviced and repaired by a Generac Authorized Service Dealer or other compe- tent, qualified electrician or installation technician who is familiar with applicable codes, standards and regulations. The operator also must comply with all such codes, standards and regulations.

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 nothing that might render the unit unsafe or in noncompliance with the aforementioned codes, standards, laws and regula- tions.

The engine exhaust fumes contain carbon monoxide gas, 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 ventilat- ing air is critical to prevent buildup of explosive gases and to ensure correct generator operation. Do not alter the installation or permit even partial blockage of ventilation provisions, as this can seriously affect safe operation 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.
