Automatic Standby Generator Owner’s Manual

1.1 — General Safety

Study these safety rules carefully before operating or servicing this equipment. Become familiar with this Owner’s Manual and with the unit. The 
generator 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 fundamental rules or precautions.
The manufacturer cannot anticipate every possible circumstance that might involve a hazard. The warnings 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 the manufacturer does not 
specifically recommend, ensure that it is safe for personnel. Also make sure the procedure, work method or operating technique utilized does not 
render the generator unsafe.

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 
and maintain this equipment.
Potentially lethal voltages are generated by these machines. Ensure steps are taken to make the machine safe 
before attempting to work on the generator.
Parts of the generator are rotating and/or hot during operation. Exercise care near a running generator.

The installation of this generator must always comply with applicable codes, standards, laws and regulations.

A running generator gives off DEADLY carbon monoxide, an odorless, colorless, poisonous gas. Breathing carbon 
monoxide can cause dizziness, throbbing temples, nausea, muscular twitching, headache, vomiting, weakness, 
sleepiness, inability to think clearly, fainting, unconsciousness or even death.

The control panel for this unit is intended to be operated by qualified service personnel only.

1.2 — General Safety Hazards

• For safety reasons, this equipment should only

 

be installed, serviced and repaired by a Service Dealer or other competent, qualified electri-

cian or installation technician who is familiar with applicable codes, standards, regulations and product Installation Manual guidelines. The 
operator also must comply with all such codes, standards, regulations and product Installation Manual guidelines.

• 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. DO NOT alter or add to the exhaust system or do anything that might render the system unsafe or in 
noncompliance with applicable codes and standards.

• Install a carbon monoxide alarm indoors, according to manufacturer’s instructions/recommendations.
• Adequate, unobstructed flow of cooling and ventilating air is critical for 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. The generator MUST be installed and 
operated outdoors only.

• 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.

• 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 Dealer for parts needing repair or replacement.
• Before performing any maintenance on the generator, remove the control panel fuse and disconnect the Negative (—) battery cable to pre-

vent accidental startup. When disconnecting battery cables always remove the NEGATIVE (NEG or “—”) cable first, then remove the 
POSITVE (POS, or “+”) cable. When reconnecting the cables, connect the POSITIVE cable first, and the NEGATIVE 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 

conditions from leaking exhaust gases, fuel leakage, oil leakage, etc.
