Safety Rules

IMPACT-36 plus II Recreational Vehicle Generator

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

Inspect the generator regularly, and contact the 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 startup. First, disconnect the cable from the battery post, indicated by a NEGATIVE, NEG, or

(–). Reconnect this cable last.

Never use the generator, or any of its parts, as a step. Stepping on the unit can stress and break parts, resulting in dangerous operating conditions due to leaking exhaust gases, fuel leakage, oil leak- age, etc.

Never insert any tool or other object through open- ings in the generator interior, even if the unit is not running. Seriouse injury or damage to the equip- ment may occur.

ELECTRICAL HAZARDS

The generator covered by this manual produces dangerous electrical voltages and can cause fatal electrical shock. Avoid contact with bare wires, ter- minals, connections, etc., while the unit is running. Before operating the generator, ensure all appro- priate covers, guards, and barriers are in place . If work must be donearound an operating unit, stand on an insulated, dry surface to reduce shock hazard.

Do not handle any kind of electrical device while standing in water, while barefoot, or while hands or feet are wet. DANGEROUS ELECTRICAL SHOCK MAY RESULT.

During installation onto the vehicle, have the gen- erator properly grounded (bonded), either by solid mounting to the vehicle frame or chassis, or by means of an approved bonding conductor. DO NOT disconnect the bonding conductor, if so equipped. DO NOT reconnect the bonding conduc- tor to any generator part that might be removed or disassembled during routine maintenance. If the grounding conductor must be replaced, use only a flexible conductor that is of No. 8 American Wire Gauge (AWG) copper wire minimum.

In case of an accident caused by electric shock, immediately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor. AVOID DIRECT CONTACT WITH THE VICTIM. Use a nonconduct- ing implement, such as, a dry rope or board, to free the victim from the live conductor. If the victim is unconscious, apply first aid and get immediate medical help.

Never wear jewelry when working on this equip- ment. Jewelry can conduct electricity, resulting in electric shock, or may get caught in moving com- ponents, causing, injury.

FIRE HAZARDS

For fire safety, the generator must be installed and maintained properly. Installation must always comply with NFPA 70 (latest edition), “National Electrical Code”, Article 551, and NFPA 1192 (lat- est edition), “Standard for Recreational Vehicles”, along with all applicable codes, standards, laws, and regulations. Adhere strictly to local, state, and federal electrical and building codes. Comply with regulations the Occupational Safety and Health Administration (OSHA) has established. Also, ensure that the generator is installed in accor- dance with the manufacturer’s instructions and recommendations. After proper installation, do nothing that might alter the installation and render the unit in noncompliance with the aforemen- tioned codes, standards, laws, and regulations.

Keep a fire extinguisher in the vehicle at all times. Extinguishers rated “ABC” by the National Fire Protection Association are appropriate for use on the recreational vehicle generator electrical sys- tem. Keep the extinguisher properly charged and be familiar with its use. If there are any questions pertaining to fire extinguishers, consult the local fire department.

EXPLOSION HAZARDS

Do not smoke around the generator. Wipe off any fuel or oil spills immediately. Ensure that no com- bustible material is left in the generator compart- ment, or on or near the generator, as FIRE or EXPLOSION may result. Keep the area surround- ing the generator clean and free of debris.

All fuel types are potentially FLAMMABLE and/or EXPLOSIVE and should be handled with care. Comply with all laws regulating the storage and handling of fuels. Inspect the unit’s fuel system fre- quently and correct any leaks immediately. Before placing this equipment into service, the fuel supply lines must be properly installed, purged, and leak- tested according to applicable fuel-gas codes.
