Generac Power Systems QT05030AVAN Owner'S Manual Download Page 4

Study these SAFETY RULES carefully before installing, operating 
or servicing this equipment. Become familiar with this Owner’s 
Manual and with the unit. The generator can operate safely, effi-
ciently 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 a procedure, work method or operating technique is used that 
the manufacturer does not specifically recommend, ensure that it 
is safe for others. Also make sure the procedure, work method or 
operating technique utilized does not render the generator unsafe.

n

 

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 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.

n

 

Parts of the generator are rotating and/or 

hot during operation. Exercise care near run-

ning generators. 

GENERAL HAZARDS

For safety reasons, the manufacturer recommends that this 

• 

equipment be installed, serviced and repaired by an Authorized 

Service Dealer or other competent, qualified electrician or instal-

lation 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, stan-

dards, 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 generator is installed, operat-

ed and serviced in accordance with the manufacturer’s instruc-

tions and recommendations. Following installation, do nothing 

that might render the unit unsafe or in noncompliance with the 

aforementioned codes, standards, laws and regulations.

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, adequate ventilation must be provided. This should 

be considered prior to installing the generator. The unit should 

be positioned to direct exhaust gasses safely away from any 

building where people, animals, etc., will not be harmed. Any 

exhaust stacks that ship loose with the unit must be installed 

properly per the manufacturer's instruction, and in strict compli-

ance 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 generator 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 uncluttered. 

• 

Remove any materials that could become hazardous.

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 promptly repair or replace 

• 

all worn, damaged or defective parts using only factory-

approved parts.

Before performing any maintenance on the generator, discon-

• 

nect its battery cables to prevent accidental start-up. Disconnect 

the cable from the battery 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 dan-

gerous operating conditions from leaking exhaust gases, fuel 

leakage, oil leakage, etc.

ELECTRICAL HAZARDS

All Stationary Emergency Generators covered by this manual 

• 

produce dangerous electrical voltages and can cause fatal 

electrical shock. Utility power delivers extremely high and dan-

gerous voltages to the transfer switch as well as the generator. 

Avoid contact with bare wires, terminals, connections, etc., 

on the generator as well as the transfer switch, if applicable. 

Ensure all appropriate covers, guards and barriers are in place 

before operating the generator. If work must be done around 

an operating unit, stand on an insulated, dry surface to reduce 

shock hazard.

Do not handle any kind of electrical device while stand-

• 

ing in water, while barefoot, or while hands or feet are wet. 

DANGEROUS ELECTRICAL SHOCK MAY RESULT.

n

 

Save These Instructions – The manufacturer suggests that these rules for safe operation be copied 
and posted in potential hazard areas. Safety should be stressed to all operators, potential operators, 
and service and repair technicians for this equipment.
