PRIMEPACT 66G and 66LP Recreational Vehicle Generators

SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation be copied and posted in potential hazard areas of the recreational vehicle. Safety should be stressed to all operators and potential operators of this equipment.

WARNING:

GENERAL HAZARDS

The engine exhaust from this product contains chemicals known to the state

of California to cause cancer, birth defects or other reproductive harm.

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 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 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 you use a procedure, work method or operating tech- nique Generac does not specifically recommend, you must satisfy yourself that it is safe for you and others. You also must make sure the procedure, work method or operating technique that you choose does not render the generator unsafe.

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 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 generators.

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

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. This exhaust sys- tem must be installed properly, in strict compli- ance with applicable codes and standards. Following installation, you must do nothing that might render the system unsafe or in noncompli- ance with such codes and standards. The genera- tor compartment must be completely vapor sealed from the vehicle interior. There must be no possi- bility of exhaust fumes entering the vehicle interi- or. 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 causes serious damage to the generator. Do not alter the installation or per- mit even partial blockage of ventilation provisions, as this can seriously affect safe operation of the generator.

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

Inspect the generator regularly, and contact your nearest Generac Authorized Service Dealer imme- diately for parts needing repair or replacement.

Before performing any maintenance on the genera- tor, disconnect its battery cables to prevent acci- dental start up. Disconnect the cable from the bat- tery post indicated by a NEGATIVE, NEG or (–) first. Reconnect that cable last.

Never use the generator or any of its parts as a step. Stepping on the unit can stress and break parts, and may result in dangerous operating con- ditions from leaking exhaust gases, fuel leakage, oil leakage, etc.
